wsm case life?

[j_22250]

i'm shooting a 270wsm and had case neck split on me after only being reloaded twice,so 2 firings). winchester brass and 65grs of h3831sc. they are a little warm and i need to back 'em off about a grain or so, but the only sign is cratered primers so not to warm i'm guessing. i neck sized them, but they were a little tight in my chamber. do most fl size or jst bump the shoulder? is this done with the fl die,like neck sizing with fl di)? also would it be wise to anneal brass after only being shot twice?

btw these shot great and were all touching at 100yrds; this was achieved after switching to standard primers.

I've loaded my Winchester 270 WSM cases 3x with no problems. I am going to anneal them before the next loading. I'm using Reloder 22, but not a max load, to allow for some temperature change.

Dont have any experience with the .270 WSM, but with my 300 WSM I have a match 50 piece set of brass that has 7 loads through it and still going strong 67.6 grns of 4831SC under a 155 grn Scenar. I aneal every fourth reloading, and full length resize every time.

My 7wsm cases go about 8 reloads before visiting the recycle bin, but I anneal after every 2 to 3 firings. I also full-size,push back the shoulder by 0.0015 every firing)
