i would agree with the primers getting loose after only one or two shots. then they stay about the same for a while. i shoot with my face on the receiver so i'm a little concerned about the loose primer thing. i got some RWS jeffery's brass to form into the edge, thought this might wear the barrel out before the brass.

Dave, Mine aren't what I would call 'loose', they are 'looser' than new brass, but not loose like my 338AM gets after 3-4 shots.

I would concur with your guys findings on the Rem brass. I can mine at 8 loads just because it is cheap insurance. I notice the pockets loosen up some the first or second firing but don't change after that. I run 93.0 gr H1000 , 300 SMK, CCI 250, OAL 3.785" and get 2818 fps with an ES of 6-10 fps really regular.

Shawn, is that 3.785" at or in the lands? Typically what do they shoot the best at? I know every rifle is different but with as many rifles that like the same load there has to be some common ground there I would think.

Re: 338 Edge, Brass life test. Rem 300RUM brass
Not exactly 338 EDGE, but was able to run the 300 RUM rem brass to 8 firings as well.
I haven't shot my 338 EDGE cases but 2x, but I suspect they'll go easily to 8x times as well. Am using 92g H-1000, cci 250, 3.780", 2840fps.
I to have noticed after about 2-3 firings, the pockets loosen up, but still no where near the point where they wont hold a primer tightly. I figure If I get 8x on Rem cases in RUM calibers, I"m doing OK.

Re: 338 Edge, Brass life test. Rem 300RUM brass
Magman,
It is kind of funny, I have built Edges with COAL's from 3.685" to 4.030" and land jump from .000" to .100" and it just dosen't seem to matter much. They all seem to like the H1000, CCI 250, 300 SMK combo. The powder charge vary a little 92-94 grains but the rest seems to work no matter what you do, within reason. 92 grains is my standard test load and most people never bother to try anything else after they shoot it.

Shawn,
Have you had much luck with Retumbo? My 338 RUM likes the H1000- but I got hooked into buying 8# of Retumbo. Luckily these big guns are powder hungry.

Tried some and it wasn't bad just liked the H1000 better.
