Re: Brass Wars-338 Lapua

Do you plan to neck size or full length size?

I might suggest you neck turn to a consistent thickness so that you don't work one case brand harder than the others.

I would think you could do load development along the way so long as you give consistent treatment to each brand of brass.

You will expend significant barrel life on 40+ pieces of brass. ...especially if you shoot moderate loads, have a good die setup, and anneal periodically.

The question can be put forth from various perspectives...
i.e.
How quickly will each brand fail if I stress them?
vs
How long can I make each brand last if I take care of them?

Keep us posted.

Re: Brass Wars-338 Lapua

Update: Shot 60 rounds yesterday. 30 Berger 300 OTM and 30 Hornady 285's. Berger's velocity with 90.0 H1000 was 2640 FPS and the Hornady 285's were 2700 FPS with the same charge. Best group with the Berger's was 1" at 100 yards. Hornady average was 1/2 moa with two groups at .250. Think I'm going to stick with the 285's from here. The Hornady brass after the second reload is now NOT STICKING at all. I have been full length resizing and annealing every time. The Lapua brass has the best ES and SD though. So far I have played with seating depth and charges from 90.0 to 92.0. Not enough testing yet but I'm probably going to charge the next batch of 40 with 88gr H1000, and 88-89.5 gr on my others. Gonna lose velocity but hopefully gain on accuracy. Maybe, hopefully. Getting very used to the magnum recoil. It helps to let the 338 cool down and shoot the 223 and 308. Made a rear rest squeeze bag out of a old Army sock filled with 6mm airsoft BB's, works extremely well.

Question, I have some H4831 laying around, is it worth it to try that out or stick with the H1000? I've got two pounds of H1000 left and plan on trying some Retumbo when the 1000 is gone but the 4831 is just sitting there...

Re: Brass Wars-338 Lapua

Either of the 4831s are actually a bit on the fast side for best performance in the 338 LM. You're going to bump into pressures before you reach the same top end velocities you're getting with either the H1000 or Retumbo. I'd say stick with the original game plan, and I'm sure there's something else in the safe that'll make better use of that 4831.

Re: Brass Wars-338 Lapua

Thanks. Won't use the 4831. It is listed in reloading manuals for lighter 338 bullets but wanted to ask first. I'll get some Retumbo and play with that but I'm just guessing that 1/2 moa with the 285's and H1000 might be ticket. Not much to improve on there. This 338 magnum is really fun to shoot. Might have to get a custom stick made in 338 LM!

Re: Brass Wars-338 Lapua

With moderate loads, I'm thinking the brass will last longer than you would like. Way longer.
