Looked in the reloading depot and not much there as far as 338 LM. Was wondering if anyone wanted to generate more.

From my Blaser .338LM I use 94.5gr of Retumbo, Lapua Brass N/S with a 364 bushing, gm215M, SPAOL 3.950, Topped with 250 SMK

Re: Anyone want to share any 338 LM load data?
Lapua brass, Federal 215 primer, 300 gr Lapua Scenar, 102gr Us869. This recipe has delivered the best accuracy result for me, out of my AR-30.

Re: Anyone want to share any 338 LM load data?
those loads of REL 25 are too hot in my gun, I have an old lot that must be faster because when I loaded 91 grains with the 300 SMK then I got 3050 fps out of my 26" tube.
I would start at 89 grains for the 250 grainers and at 86 grains for the 300 grainers to be safe.

Re: Anyone want to share any 338 LM load data?
My rifle has a longer throat, so I can load to 3.750 OAL.
Lapua brass, Fed 215M, 95.0 gr. Retumbo, 300 Scenar.
MV ~ 2880 out of a 28.5" Bartlein 1:9.4.

There appears to be larger than expected variance lot to lot with RL25 lately. This is making Retumbo look like a better option.
FWIW, with my .338LM SRS, this is the load that's currently working best for me:
250 Scenar
Lapua Brass
Fed 215M
94gr RL25
COAL 3.554" (still playing with seating depth)
This gives me approx 3000 fps

Surgeon XL - own build 9 twist barrel, chamber min SAAMI spec.
94.5g H1000 under Fed 215 and 250 SMK.
Loaded to SAAMI spec (.010" short of mag length)
2980fps, sub half - quarter MOA.
Very stable load.
This also works with 250 Secenar and 250 Lockbase.

Hunting load:

Didn't like Retumbo personally, found the recoil impulse to be a lot sharper with it over RL 22.

Factory DTA SRS .338LM / 26"bbl / Twist 10"
Was working loads for MAX signs of pressure. Still waiting to fire at distance and hopefully use the 93gr load in lower temperature with less signs of pressure on primer "primer flow".
3 of each in group, total of 18 rounds in below target at 100 yards. Same hold.

Re: Anyone want to share any 338 LM load data?
Sako TRG-S M995 action , 30" Rock/ABS 1-9.4" twist barrel.
89.5grs H1000, 87grs RL25 both with the 300gr SMK loaded to 3.785" COAL give me 2775 fps and an average of .75 moa out to 1K.
Just tried 90.5 and 91grs of Retumbo, haven't chronoed yet but looks promising with .5 moa groups at 300yds in testing.
These loads are about max, my rifle seems to get max pressure with less powder then most of the others I've read about.

I though the same thing. I removed the extractor tried to seat the case on the bolt face to fit the primer in the pin hole, it won't fit back in. Must have expanded after extraction.
Do you know anyone who has continued to use hot loads with this indication, with any negative results?
If this is no problem I'll do a large string with this load (94 grains = 3,178 FPS " *3 FPS Deviation*) to see if the deviation remains near 10 fps or less.
I'll take 200 fps over barrel life any day.

Re: Anyone want to share any 338 LM load data?
That VVn560 looks like it really works in the Lap-mag. I found some in a little sporting goods store Monday and was interested until I saw the $34.95 price tag on the one lb. can. I believe I can keep struggling along with Retumbo. I realize the 338LM is never going to be cheap to shoot, but I don't see enough velocity improvement with the N560 to justify the added cost. Also it seems VV powders are not as readily available out here in the sticks.
Thanks for posting your results Fredo, always appreciate useful info!

91 grains H4831 SC
250 Scenar
215M
Lapua brass
Loaded to mag length
.2-.3 at 100 I dont know velocity but its 7.2 mils to 1000. Luckily this is the same for the AW so all I have to do is sort brass between the 2.

I have offically quit using 300 SMK the 250's shoot so well that I dont think there is a need for 300's anymore.

Re: Anyone want to share any 338 LM load data?
All right, I've got about 100 rounds down my AI now and I usually take Black Hills or Lapua ammo and measure the dimensions to guide my reloading as far as ogive to head measurement. I took the simple road this time and went for OAL instead of ogive to head. I use 250 scenars and noticed when I went 3.6-3.62 on OAL I get ~2.95 on ogive to head of cartridge. My Lapua factory is ~2.884 ogive to head. You guys get comparable measurements? Anyone have ogive to head of cartridge measurement on any Black Hills 338 LM.
Thanks

My Lapua factory is ~2.884 ogive to head. You guys get comparable measurements? Anyone have ogive to head of cartridge measurement on any Black Hills 338 LM.
Thanks </div></div>
I just measured 4 pc of BH 250's and all measure 2.864 Head to Ogive
Re: Anyone want to share any 338 LM load data?
I may stay at ~2.95 then on my ogive to head measurements. I haven't had any noticeable pressure problems. The tips of the bullets always get deformed after seating so I feel the OAL measurement is not as consistent as ogive. Thanks for the measurements on the BH.

I measured today with an empty case and projectile and it appears from lands to face of bolt is 2.944". A little too close for comfort so I think I'll back off to 2.88-2.9 LOL.

What are going to be the disadvantages of using the cci magnum primers?I notice just about everyone is using federal.Out of all the powders listed above which powder creates the most consistent velocities?

I've used CCI LR Magnums out of necessity without any problems.

Haven't had the opportunity to try the CCIs with my Lapua's loads. Im difinitly all for it though considering thats what I use for all my other loads for various rifle calibers. The CCI BR2 is a great product. I have no reason to doubt that their magnum primers would be any different. I cant find any to try out though.
