A very specialized gunsmithing job is reboring a rifle barrel to a larger caliber. Watch along as Larry Potterfield, Founder of MidwayUSA, demonstrates the process of reboring and rechambering a Winchester 1885 Low Wall (made in 1891) from the long obsolete caliber of 32 rimfire to 357 Magnum.

"Let me show you how it's done. Step one: Send it off to someone who knows how it's done." Good advice.
If Larry potterfield cant do it. Not many can lol
Well... that is the best advice.
I do like that it started with essentially “I cant do this so im outsourcing it”. I completely understand why he had to do that, i just found it funny
@@davidftellez ppl
ahahahaha
How to rebore a rifle. Step 1:Buy another rifle. Step 2:Tell your wife it's the same rifle you just replaced the stock.
BINGO!
How to rebore a rifle. Step 1: Disassemble the firearm completely. Step 2: Mail barrel to Delta Gun Shop. Step 3: ?????? Step 4: Profit
AHAAHAHAHAHAHAHA
Good presentation. I honestly thought that "How to Rebore a Rifle Barrel" meant it would show how you can rebore a barrel yourself.
@Billy But Whole Yeah advanced machinery like a lathe and a mill truly cutting edge technology right there.
Were talking the common man who wants to do his own gun and save himself some money . Forgetting the $10000 lathe? the other tools he peddles to do the job would be prohibitive ! Why didn't he just say this how a gunship would do it. Must think the common man is stupid
The tooling you need to do it properly the way they showed would be prohibitively expensive. And you only get one try.
Generally unless your a professional, dont.
You can.
It's obvious that doing this kind of work takes a lot of planning. But what takes as much, maybe even more, planning, is documenting the whole process in such a professional manner. Thank you! 👍
Thanks for teaching me how to pay an unknown person an unknown amount of money to re-bore a rifle barrel for me.
Check your glasses, I can clearly read "Delta Gun Group" in the caption.
I bet you go through A LOT of Puffs brand Kleenex.
@@snootdingo9365 Why puffs?
@@marcosmota1094 good eyes. Sad to say, only a couple of years after Midway recorded this, the reboring man (Jim DuBell of Delta Gun Shop) cashed in his final chips.
@@marcosmota1094 I think you missed the point. The title of the video was concerning how to re-bore a rifle. Yet the only thing concerning that was when he mentioned that he shipped it off to be re-bore somewhere else. The majority of the video was mainly about centering the firing pin, making sure the new caliber will sit flush in, and touching up the barrel and swapping marking. No re-boring whatsoever.
Whoah. Amazing. Guess I'll try this later with my hand dremel.
Lol dont forget to use your angle grinder to grind off the old markings.
careful, bubba
Lmao
funny - good chuckle :D
So, the way to re bore a rifle is to have someone else do it. Got it.
ardvarkkkkk1 says, "So, the way to re bore a rifle is to have someone else do it. Got it." So, you do your own paint color mixing, your own upholstery when restoring a car, your own chainsaw sharpening, etc. right? .
I don't make videos on how to upholster a car seat then send it out to have it done.
Nonya Bidness And your point?
Nonya Bidness Yes, I would. I am fully capable of building the entire rifle from bar stock. I was interested in seeing the process that the title said the vid was about. Say you watched a video on how to rebuild a carburetor. They show you how to take it off and then say to send it out. Was that helpful?
ardvarkkkkk1 We are all very sorry for your disappointment. .
How to rebore a rifle barrel in 5 simple steps. Step 1: Remove the barrel from the rifle and wrap it in something protective like plastic or bubble wrap Step 2: Place the barrel in a box. Fill the box with something soft so it doesn't roll around during transportation. Step 3: Print a shipping label with the address of somebody who knows how to rebore a rifle barrel and tape it to the box. Step 4: Take the box to a local post office. Step 5: Wait for somebody to rebore the rifle barrel for you and send it back.
you forgot a step 6, pay the hefty shop fee.
Yep that about it. Many rifles have been ruined by DIY peeps. I'm a machinist and even I would mail it out.
Yeah having machine knowledge clearly isn't enough. The people who do this have a very specific process and quality control.
Right, even the chamber reaming process is a challenge. I wish they would have stressed how tedious it is to get good concentricity with a 4 jaw chuck and a spider, but also why it's about the best way to do it. Machinists have a peculiar form of OCD along with a supernatural level patience, because they have to. Much respect to the guys doing that kind of precision work, especially on a manual machine!. It's not as easy as video makes it out to be.
great video! it touched home twice as my dad was a machinist and my granddad collects old rifles. My dad passed some years back of cancer but my old grandpa is still rocking on strong at 89. he remembers everything about collecting his guns (about 100 old winchester levers, Remingtons and some others) and I still love to listen to his stories.
"You send it out and someone drills it out" Great video....
I love how you bring these old guns back to life. Truly a beautiful art in itself.
Yes, sophiscicated work they are
For all those mocking the video, this is the first video of his I've seen where he had to send something out for someone else to do. That means it's extremely difficult.
Or just doesn't have lathe large enough for this job. They are either very expensive or requires a LOT of work to bring them to required precision.
It's actually not.
@@OlderSpud It doesn't even require a lathe. Reboring is often done vertically using a piloted drill and followed with a piloted reamer. The chamber is opened up with a chamber reamer; this can be done entirely by hand on your lap. The rifling is done in a rifling press.
Do you really believe he does all this work his self?
There are people who specialize in gunsmithing, and there are people who specialize in making gun parts. Your car mechanic probably doesn't turn crankshafts either.
Great video. Just one comment: A buyer refers to a brown gun as a "roach", yet when he resells same gun its referred to as "patina".
Pretty much, I got a octagon barrel 1857 44-40 bought for 500 , have been offered up to 13,500..... have been watching prices.. seen some mint ones go for 35, 45 k
Very nice original patina, for that beat up worthless rusted gun.
excellent video, I understand fully about the specialized need of another company to rebore, you did great work on a fun old gun & pulling it all together.. thanks
Jim Dubell at Delta Gun Shop was my father-in-law, he passed away a few years ago. He was an artist and a master gunsmith, It was pretty cool to stumble across this video.
He put old rifles back into service preserving history, pretty darn cool
After sighting in at 60 feet, I could easily cover 5 shots with a nickel kzhead.infoUgkxQt2uORDRfFOVSrO4idv4B90ThT6EOnEL ! Truly a pleasure to shoot! Scope was easy to adjust for eye relief. Only problem the varmints must have seen it delivered lol!Update: So impressed with shot groups at 30 yards I purchased a Hammers 3×9 with adjustable Objective scope! Now a true nail driver!
So great to see a vintage rifle like that given new life.
That was really cool to see. The etching part I liked the most, that was pretty clever.
I'm sitting in my local pub in England, we're not allowed firearms here, i love guns and i love engineering and this made me stay for another pint ...fantastic thank you
you could own a firearm very similar to this. check out some gun clubs in your local area
Larry, I alway find these gunsmithing videos as entertaining as they are infromative.
What was informative about it?? How to mail something??
Larry Potterfield: He's not just the Midway USA founder and CEO, he's also a gunsmith!
@bert smith I get that vibe, too. I've bought quite a lot of stuff from Midway USA over the years, especially reloading equipment and components.
As just a quick overview of the process, I found the video fairly interesting. It wasn't unnecessarily long and drawn out like so many KZhead video tend to be. Delta Gun Shop is one of the very few shops reboring barrels these days so no mystery there. An accurate rebore isn't really something the average gunsmith is set up to do so I'm not surprised Larry sent it out.
You're a wizard Larry.
Sweet... true American Craftsmanship!
I really love Larry's videos. they make me want to be a gunsmith. It's too bad someone let that gun get rusty. 32 rim-fire was the first cased round. Smith, Wesson, Winchester & Henry all worked together on that rifle & cartridge. That was a real piece of history.
Well, no, not at all. .32 Rimfire was designed in 1860. Some 15 years after Flobert invented mettalic rimfire cartridge.
I don't think that was rust. Before bluing, there was a preservative called Browning. It functioned in much the same way, by allowing a controlled amount of rust to adhere to the service and protect it from furth rust.
Very good, step-by-step video with clear descriptions and explanations.
I am originally from the UK so octagonal barrels are rarely seen here as firearms are highly restricted. I have to say it is wonderful to see videos like this, the skill involved, the craftsmanship and the history surrounding the evolution of firearms.
Its not as restricted as u think
@@Monster3Games I used to have a shotgun license so I know exactly how restrictive it is. I gave it up as I no longer have time to shoot but from those I know who still own them I am told it is worse than ever. Owning a rifle is even more difficult as you have to demonstrate a need for it. The son of a gamekeeper friend wanted to target shoot and they refused his application even though his father already owned rifles for his job and they lived in the same house. I'm sure you are also aware of our Olympic athletes who had to go abroad to practice as they couldn't get a license to own a .22 handgun. The UK gun laws are ridiculous and it's because we had a couple of awful incidents. One of which (Dunblane) should never have happened as the man had a history of seriously unstable behaviour, was ejected from the scouts because he was likely abusing young boys, a police officer had put in a formal request to have his firearms taken (which was refused) and a justice of the peace who had been his friend for years was the one who signed his renewal for a firearms license. This corruption lead to the ban rather than having all those involved thrown in a cell.
You are really an amazing gunsmither i have ever seen,,, great vid,,,
Man, that Larry makes it look sooooooo easy! Great personality for these training videos. Fantastic job Larry, thank you.
He reminds me of the Cabela's voice-over guy.
Right at the time stamp, @1:24 .... the still picture that only last for a second or two, showing the bare rifle clamped in/on the carriage slide.. did you all notice the rocker arm and push rod cantilever clamp system to lock the barrel down... strange, but interesting while worthy of saying, exceptionally clever... and something tells me, that this clever "reuse" of parts to make this clamp system, has been in use on this machine for years, if not decades.... I am glad I watched this video...
I don't understand all the snide comments. This is years of experience, first coming up with the idea, then assembling all the resources, to effectively recycle a firearm that exceeds in many ways the quality of modern, high rate production arms, and only equaled by true custom built firearms costing thousands. So this is an excellent value for the discerning customer, and again, for those able to see possibilities beyond their own small minds, may call someone like Larry Potterfield, and discuss their next project. Thank you @MidwayUSA.
He's makes it look so simple :)
fellow from Australia enjoying this video wishing i lived in the days before heavy restrictions on guns, im absolutely not bothered to get a license it will end up costing up to 3000 dollars if i did, although this particular rifle is probably considered an antique and wouldnt even need a license because its older than 1901 and uses an obsolete caliber
i am a firearm owner in aus as well. the licensing (while not cheap) is not 3000$ . its more 500$ or so depending where you do your safety training course. i do agree on the the wish abt living before heavy restrictions
Licence is no where near $3000, more along the lines of $400 odd for everything, unless you live in WA and need to buy the rifle, scope and safe first.
You could always move to America
+Draeios Kronos hahahaha you're kidding right? If i wanted better gun laws I'd move to New Zealand.. I wouldn't be able to put up with American drawl let alone the lifestyle in the US.
3000 dollars to get a firearm license? you are smoking crack. it costs less than a car license..... the catch is you have to purchase a firearm for the license to ever actually be issued..... still not even close to 3 grand though.
Good video. I wouldn’t trust a reboring to anyone but someone with the knowledge, skill and tools to safely do the job. Don’t want to wonder if the firearm is going to blow up on you every time you fire it! I’m impressed with the tools you have and the parts you did on your own as well. Well done.
" Give it to someone who knows what they're doing" is great advice ..
love seeing the master at work
Don't you mean masturbator
Great video!
.Truly amazing, a real craftsman. His skill is second to none. 👍👍👍
Beautiful Rifle... great work also didn't know that was possible
"rebore" does not belong anywhere in this video.
rerifling needs very high accuracy so it's hard to do it well,good job!
I miss these videos so much - with you would pump out a few more of these.
Watching your work and your firearms reminds me of when firearms were works of art and engineering as well as a weapon. Beautiful wood, blued steel and artful craftsmanship. Along with custom leather holsters and ornate engraved belts...a man was proud of his weapons and rigs. Now it seems to be all plastic. Something goes wrong..toss it and buy new. The new everythings disposable attitude. Thank You Larry for keeping the greatness alive!!
The future is here, old man. And you seem to deny it
#Cantstopthesignal
I was always fond of octogon barrels. I remember being 9 and checking out a book of old guns from school. I even asked Mr. Froescyth why they weren't round. He thought it had added strength over round ones. And it was normal for the time.
They unscrewed like a bolt. Pretty awesome machine work for such a long time ago. When it stopped threading it was on sight? How were they doing this in the 1850's lol?? The craftsman ship involved and techniques this day in Midway videos are amazing!!
tom smith that machine work is easy is called indexing and is justa function of facing the shoulder .... its a lil math involved..... a scew is a ramp and moving so far on that ramp equals a certain distance so if you remove one thousandth on a 90 degree ramp the barrel will advance an equal distance one thousandth.... But at the thread not the outer circumfrence of the barrel. ?.. a less aggresive ramp ..... screw barrels might advance 18 to one..... so you do your math is things that are not taught in school because teachers no longer know math lol If you can't figure it out Google it is really easy once you do it once..... If you can't figure it you can use a shim to determine how much the barrel will rotate for a given amount of material added which will match removal of material ..... Of course you can sneak up on it ..... Don't forget metal will crush and you can assist slightly the alignment of the site by crushing more or less.....
amazing thanks for the knowledge friend!
05:21 when a gun smith fires a weapon they first look at the cartridge before looking at the target ;D
Larry, I now have two reasons to like Midway, you and Dave Brown.
If I can get my gunsmithing skills to Larrys level I wouldn't be an amateur anymore in this field.
Just because the bluing or stoving of a rifle has faded or changed color does not mean it has lost all of it's value. Refinishing and modifying surely ruins any collector value. Keeping them as original as possible preserves their value. Granted a shiny original is worth the most but a dinged up discolored rifle still has some collector value.
Agree.
what good is a .32 rim fire? That .357 conversion is a great project and makes that old gun usable again.
Something tells me Larry Potterfield isn't concerned about the loss of value here. Plus it was a fun project for him.
thought there was Ganna be more video of the actual process. not still photos and small talk.
Nice job. That’s looks like a fun project and end result
I like the work you did id be afraid to do work like that.great gun
Incorrectly named, should be called How to rechamber an already rebored barrel.
wow this guy is super talented with guns. wish I had his expertise
Larry has some neat tools in his garage!!
Magnífico trabajo, como siempre.
Ah, refreshing, rich guy hobbies.
joesbarandgrill100 ohh do do i hear poor peoples crying?? ahhahahahahahaaha
Do I hear a moron laughing? What he said is true and you cant deny that.
How to Rebore a Rifle Barrel: Send it to someone who knows what they're doing. Thanks a lot...
I absolutely love this video I’ve watched it several times I would love to have that raffle
You are a very humble person.
When Larry says "I'd like to shoot it" he means im take this here antique and make a better gun than you'll ever own. And thats the way it is.
"Gunsmithing - How to Rebore a Rifle Barrel" - reboring is a very specialized gunsmithing job, so i'll send it out.. GG clickbait
+Žiga Strmšek It requires a specialized boring/rifling machine which not everyone has. There's no choice but to send that work to a shop that does it.
so why title the video that then?
Watch something called Colonial Gunsmith. It's not that special.
You can make both the boring and the rifling machine.
Yeah this guy in the video is a moron. Titles the video how to re bore a rifle barrel then just sends it away for someone else to do it.
This is the first time I've ever seen Larry NOT do all the work himself. Impressive either way
One of the coolest gunsmithing jobs I have ever seen. Very cool to make a shooting firearm out of one like that. Nicely done.
I wish I had the skill and patience to do something like this.
I only can saying a word - Amazing!
Francisco Lee l
Very nicely done video Larry
I rechambered a few surplus 30-06 machine gun barrels into .308 Win to put onto type 99 7.7mm Japanese rifles. Everything including surplus barrel, trigger job, restock, scope and original rifles all for under $200. Great conversions, accurate and used to be inexpensive.
+Absaalookemensch Do you do this work yourself? Or, can you tell me where I can get that kind of smithing done?
Used to do it ourselves, but got out of the home gunsmithing hobby years ago. If you can find surplus 30-06 machine gun barrels today, they are snatched-up by 1919 machine gun owners. Sadly, everything firearm related has become prohibitively expensive. We used to buy primers, $10/1000 and 8lb bags of H414 or other powders. Today, it's probably less expensive to buy a factory made Remington, Winchester or similar rifle. Ahhhh the good old days, when we could afford to shoot about 1,000 rounds a month. Fajen or Bishop training 90% inletted blanks were $10 each. Good Missouri hardwood with nice grain. Sorry for the "progress" the world had made.
You should change the name of the video... You didn't show us anything about how to rebore the rifle, you only spoke vaguely about what someone else is going to do...
Awesome video. But is the new bore not lined with chrome?
SurfingBullDog chrome lining a barrel is generally for firearms that will see either corrosive ammo, or high volumes of ammo, or both. This rifle won't fit into that category.
short answer: It's not an AK using russian military grade ammo
Wonderful work as always
That was so satisfying!!
And everybody has these in their shop.
The video isnt really a "how to" but more of a informative video for those who are curious.
How to Rebore....... Does not the leadin title imply it IS a how to article? At least English as I learned it suggests that.
durr hurr, "how it's made" videos are terrible, i don't have any of the machinery necessary to build a sailboat. this is bull!
Frederick Wise yourea fucking moron the video isnt "how to rebore a barrel for idiots with no tools", so fuck off
yeah I'll hold off raking the leaves till tomorrow, and do this real quick.
yama hama
Very nice job Sir.
This is probably my favorite project I've seen you do. Excellent job.
So............how did it shoot?
You should rename the title to "How to get somebody else to do your work and relax at home"
Are you here just for likes man, did you even watch? No one owns a gun boring machine.
+fla playa I watched.. What part do you think I missed? It doesn't matter how common or easily accessible the machinery is, he sent it away! So therefore it's a "how-to REFINISH a rifle" video, not "how-to REBORE a rifle" video. Besides the immense amount of likes I'm getting on this comment why ya hatin?
Danny M Do you own a gun drilling machine? Bet you 10 bucks you can't find one in ten minutes. QUIT YOUR BITCHING. 11:25 Eastern.
+fla playa you don't understand my point, it's not about how rare the machinery is it's about claiming how to do something you're not actually doing yourself. I don't own gun drilling machine and I don't have a CNC machine either, all the more reason for me not to make any "how to CNC" project videos. I'm assuming you think it would be acceptable for him to make a "how to build a rocket" video and give NASA a call?
Danny M You have safety glasses on. Are they to deflect comments as you type all day? Tell me and be honest, what do you do for a living? Porn, or serial killer? I liked the video. You didn't. You have 8 likes now. Proud?
Nice and clean workshop.
5:20 extractor worked flawlessly.
question, can you rebore to a smaller calibr?
Yes, It's called a barrel liner.
or sleeving.
Yes, and it's actually easier (and probably cheaper) to do that since barrel liners are pre made and already rifled.
but wouldn't you still have to have the original bore rebored anyway to make a good fit with a new liner? I would say yes.
It depends on what sort of change in caliber we're talking. Sleeving from a .45 LC down to a .22 LR would be fairly straightforward (minus the differences in firing pins, extractors, etc.) because there's a large difference in caliber. Going from 7.92mm to 7.62mm, on the other hand, would probably require the barrel to be bored wider before sleeving (just as an example). When in doubt, ask a professional gunsmith :)
A few hours of work, plus $20,000 in equipment.
You too can make yourself a new $200 barrel without having to buy a new one!
Wow, I wish I could buy that rifle from you. I like the end product a lot.
Nice job Larry!
i hate to see the price tag on that job
Probably multiple times what a new rifle costs.
Nice clean shop, you'd have a heart attack if you saw mine !
Nice work.
Craftsmanship at it’s best👍🏻
1:30 look at all dem oil
You showed everything EXCEPT the actual reboring part. Change the title of your video!
jk98 ...and then some.
It says presented by Larry not taught by Larry. He explained what was happing and presented the way to do it. Larry is a great gunsmith and machinist the rude comments or never appreciated
I don't know anything about guns but I find this really interesting
0:44 heh...bullets from game residedent evil
I think they're in Fallout, too.
É real essa marca é famosona! BrBrBr
seems expensive
Thanks for the post 👍
John here Larry got a lot of things from you guys gun screws, blueing ,sealer always like your store
There's not a ton of these old guns left. Can't we just not re-bore and re-rifle and drill holes for new firing pins and lathe down pieces and etch on it and etc and etc. Could we just try to salvage and preserve it the best we can and hang it up above the fireplace and then go outside and shoot a .357 mag out of a Henry if that all we wanted to do in the first place???
I agree with that statement. Also some people are incredibly daft with no real concept of money or historical value.
+whatever Yeah - sounds like he ruined a 100+ year old rifle, AND paid for a cheap .380 and ended up with junk. It MAY have been cool if he did all the work "in house" and taught somebody else how to do it. But he didn't
And then there's this whole "I can do whatever I want with my own property" thing. If you want to preserve guns then spend YOUR money on them and preserve them and stop whining about what others do with their money.
+whatever There's plenty of Winchester 1885's around. Just not many of them in collector condition which he explained this one is not. With that it's OK to change the caliber. Lots of them were converted into varmint rifles in the day with excellent results. Those were HiWalls though not LoWalls.
i understand what your saying and also why it was done however it still stands that what youre saying has been said for years and years. Its just a "mosin or mauser etc" and 20 later they've all gone up in price 300%. I personally think just let them be and preserve them the best you can while still enjoyuing them but thats like telling kids to leave their toy in the packaging.
This is all well and good if you have tens of thousands of dollars for the necessary tools amd machine. Plus spending $15,000+ to attend gunsmith school.
Yes, but when you add in milling machines and everything else needed, it is a hefty amount.
Michael Hill says, "This is all well and good if you have tens of thousands of dollars for the necessary tools amd machine." I think Larry is now well beyond worrying about that. .
LOL It's at least 30K to go through any of the Quality Programs.
Privat3Kag3 I know because I'm in it hahaha
Privat3Kag3 Buy a used lathe and shaper (the "predecessor" of the milling machine) can do some things that a mill can't (without a shaper attachment), drill press, vise, and a few hand tools and you're set to go. (You might have to divorce your wife first, though. lol) I don't have any of that stuff (except hand tools, electric drill, and a cheap Harbor Freight hydraulic press and I can replace rifle barrels and stuff. I can check headspace by taking a trusted cartridge case (that I have checked in a case length "headspace" gauge bought off ebay for very little compared to new price) and stacking several circles cut out of 0.0025" steel shim material and counting how many can be stacked on the case head before the bolt won't close. OK so that is amateur hobbyist compared to professional, but after a person worked on his own weapons, he would know more about whether he would want to make a career move.. .
Thanks Larry enjoy your videos
Surely Larry Potterfield can do magic with guns
