[QUOTE="Randy Tidwell, post: 1693176, member: 109136"] For confirming I am bumping the shoulder correctly, I remove the firing pin form the bolt., adjust the die to just bump the shoulder enough to allow the bolt handle to almost drop closed on an sized case. You can not feel if you have bumped the shoulder with the firing pin in the bolt. If the bolt closes with a slight resistance, I use shims to move the die out .001" at a time.

During sizing the cases, I usually double check about 15-20 rounds in the rifle again. When I seat the first bullet, I check it again in the rifle (with the firing pin still removed). If the feel has changed on closing the bolt, that usually indicates the seater die is maladjusted or the bullet is jamming the lands. I never take this setting for granted, always check it again the next time I load for that rifle. [/QUOTE]
