I was fortunate enough to get out to a military range and had the luck of finding almost 200 pieces of once fired Lapua brass for 338! It felt like Christmas!
+Mike Simpson that's better than a winning lottery ticket!
Can't wait to see how the Lapua groups. Great vid as always. I've been watching JRB for a while now and am pumped to see him starting a video series on the 6.5Creedmoor
Excellent video dude! Gonna be fun to watch and follow. That is a great deal on those scopes!
+West Desert Shooter I am very excited to get started... we will see.
watching your videos while I'm at my reloading bench!!!😀 thank you thumbs up.
+reddemon652 glad you are enjoying them.
You'll be thrilled with SWFA gear.
Yes- The SWFA scopes are the best bang for the buck. Have a 20 power and it works good. You received a great deal!
+Kai Blackout good to hear. I sure hope so. Thanks for commenting.
I like how this is starting… going to your next video
Nice series. I've been thinking about picking up one of the savage 338s soon.
+GarandThumb I couldn't resist. Never tally thought about getting a 338 lap until they started giving these things away. I just hope it shoots well.
Good luck!
I hear you. When looking at the all the savage 338s, for me the FCP is up there but I think I'm going to go with the 112.

Welcome to the channel!
Nice video. I only saw a couple newer 338LM videos…. Still messing with it?
I’ve done a lot of load data with my lapua. The best load I found was 98 gr of rl33 with 300gr Berger vld. 28” barrel, 9.4 twist, 2850fps, cold bore Es of 8. I’m gonna switch to the new nosler 265 lr accubond for better fps and only 5% less g1 bc.
+cody very interested to know how that works out. I know in the nosler 6.5 lr bullets the bc was way over rated.
THANK YOU ^^
I use the LE Wilson bullet seater with micrometer with K&M arbor press with repeatable concentricity under 1 to 1-1/2 thousandths.
Another great video. I'm interested to know your thoughts on the new press as well as the expanders. Any noticeable improvements in SD or accuracy? FYI, I use the Lee case trimmers for all rifle brass except 6.5 CM Lapua brass because of the small primer holes. Works great for me. No measuring. No setting up trimmers. Just chuck the brass and go. As for fire forming, I would like to offer something I learned with 6.5 CM. I started fire forming my Lapua brass with 95 grain V-MAX bullets for the same reason you're using the 225 grain SST - cost. When I ran low on V-MAX, I finished the fire forming process with 140 grain SSTs. The unfired headspace was 1.553" and case head diameter was .4675". After fire forming with the 95 grain V-MAX, the headspace grew by only .0015" to 1.5545" and there was no noticeable change to the case head diameter. However, after fire forming with the 140 grain SST, the headspace on the new brass grew by .007" to 1.560" and the case head diameter grew by .002" to .4695". From now on, I will be using a bullet on the larger side to do my fire forming. I will be checking out the SWFA scope. Never heard of it before this video.
+njgrplr2007 the scopes seem to have a great reputation. I am sure I will review it after I have used it a while. I plan on doing some sort of crazy roundup with neck tension variances down the road, but I can't figure out exactly how I want to do it yet. As for the press, so far I like it. Not sure I can swear on huge differences, but the combination of it and the forster dies in 6.5 creedmoor have significantly reduced my run out numbers. Video eventually.
Wish I would've caught the deal on the scopes. I have not seen anything negative about them. I have been wanting one for my 6br. Looking forward to this reloading series I have been enjoying the 6.5 creedmoor with all the great information.
+jeff young thanks. Glad you guys enjoy the channel.
I don’t know who you use for your brass but you should try Starline brass. I used to work at their company and they make some of the best reloading brass. Their specifications are much tighter than SAAMI specs and they say their brass is good for ten reloads but I heard quite a few people talking about getting thirty reloads. Their brass is ready to load right out of the box, but I would still prep it. They do not make 338 lapua yet though.
Thanks for the video, I plan to purchase the RPR 338 LM next year and this video will stay in my list since I also reload. I was wondering which powder was best, also your loading of choice with H1000. Plan to use Lyman dies, RCBS is what I use most of. Thanks again.
I have the RPR .338LM I just went from 250g* Sierra matchkings up to 300g Sierra matchkings using Federal match primers & AR2217 ADI powder (exported as H1000 ) 86g load, 250 was 94g* rifle has been fired under 200 times, fired it 7 times @ 100m 1st shot 3" wide of bullseye adjusted scope a bit next 4 shots under 1/2" 3 holes joined then scope adjust next 2 shots joined.
If you had to pick between 6.5 cm and 338 lm for long range hunting elk which would you pick?
338 lapua, 264 win mag 6.5x284, daisy bb gun, 6.5 creedmoor in that order.
In the picture it appears you bought the full length sizing die. Later you talked about fire forming the brass... wouldn't the full length sizer undo the effects of fire forming? Sorry to ask a noob question.
Typically during your FL sizing operation you will only want to push the shoulder back between. 001 to .003" at most. (Some call it bump sizing) and it is very likely that your brass will be smaller than this for the first firing.
I see you are going to use reloader 33. That powder is not listed in any of my manuals. Is there somewhere I can find that data? Thanks
Alliant website.
Nosler reloading manual.
I take a LEE Universal decapping die and lightly turn down the decapping pin so it is small enough to decap through all size firing holes...
338 LM is too wide to fit into the Lee Decapping die
You are correct!
Go west trading brass GWT. Sage reloading $1.20 a round.
Even up to $8.00 per round...Lapua's own loads but good accurate rounds can be had for less than a third of that. The 1/9.3 rate of twist to 1/9.35 is about ideal. The 1/10 doesn't do as well with the really long single feed target bullets.
Paul, I am simply look at brownells pricing here. 10 rounds of the 300 gr Lapua run about $72. Hornady factory seem to run just under $5 a trigger pull, but there is a lot of info about people with issues with savage rifles and Hornady brass not working well in this caliber. I am not paying that kind of $$ and not be able to reload the brass, or have to pound it out of my chamber. Far to often I find myself trying to save a dollar and it ends up costing me two. No one seems to argue that Lapua brass isn't the best for this application and that is why I decided to use it. I have tried the Herters 250 SMK and it seemed ok, but still yielded slightly over MOA groups. What factory ammo have you had luck with in 338 LAP?
Rumor has it..... 88.5 grains of H1000 behind the 285 ELDM is a sweet spot.
+Mike Eikey we might just have to check that rumor out. Was that a 24" barrel?
moparmadman 26"
I don't think I've ever fire formed my brass for my 338 🤷♂️
2.50 to 6 dollar a round, god I pray to the lord I could find 338 at 3 dollars a round!
Yeah, this was a few years back. I suspect most of the 338LM stuff is going to Ukraine, and what is here…
