[QUOTE="BountyHunter, post: 979195, member: 12"] Do you have the tools to measure the shoulder bump on brass that will chamber versus brass that will not? Otherwise you do not know WHAT is the problem. Adjusting the die to cam over regardless of where shoulder is or needs to be can be a recipe for trouble with excess headspace as it will routinely push the shoulder back too far but will chamber. It can also push the shoulder back to far where it starts to flair out at the body/shoulder junction and will not chamber AND it is no guarantee that you are pushing the shoulder back far enough depending on the die dimensions. It is not uncommon for dies to be too long and no amount of cam over will get the shoulder back. You have to take .0015-.0020 off the bottom of the die. If you cannot measure the brass, start with one that will not chamber and has not been messed with, back the die off the holder about 1/8 inch, and resize coming down 1/4 turn at a time and check to see if it will chamber. If you do that and get all the way to cam over, the die is too long for your chamber and you need to take some off the bottom. You could have a chamber or die or issues with both marrying up. Got to measure the brass to see what it is. NS only dies DO NOT touch the shoulder, ONLY FL or neck bushing dies touch the shoulder. [/QUOTE]
