[QUOTE="longbowelk, post: 1209093, member: 41272"] Mud: Per your statement "I seat into the lands with light loads to ensure that my cases form with 100% correct headspace" I know I have a headspace problem. While I am waiting on my go gage to ck my headspace I am going to try a 162 Hornady and/or a 175 Sierra if needed to see if it will fireform correctly without messing up the brass. I will make sure it is to the lands. My question is will the 75% powder charge get the projectile out of the barrel. You know I am having to use the heavier bullets to get to the lands and still be in the neck enough. A 139 won't even come close as it is too short. I went back and checked the brass on the lighter loads and I noticed that they even show a slight bulge in the case at the bottom. Bottom line is all the brass I have fired is going in the trash as I can not use them.
