[QUOTE="Bart B, post: 1138456, member: 5302"] Are you measuring your resized cases to see how much their shoulders are bumped back from their fired position? If you're setting the die up as its instructions say and your chamber is a bit on the long size for headspace, you will get short brass life. I don't think your load is too hot but right at about SAAMI spec for maximum. Once, I shot a Federal .308 Win. case 46 times full length sizing it every time, but only set the shoulder back .002" each time. 42 grains of IMR4895 under a Sierra 165 SBT bullet. A friend shot the same load under Sierra 168's in his .308 with a Federal case getting 56 loads on it. Both our rifles had SAAMI spec chambers. We both ran out of our test powder each time or we would have got more reloads on our single case. Many people shot that powder charge under 155-gr. match bullets in their .308's and got dozens of loads per case full length sizing them; but set the die correctly in the press. It was a safe but maximum load across all sorts of rifles; very accurate, too. [/QUOTE]
