[QUOTE="Bill Johnson, post: 1046758, member: 84129"] That won't last long. The first thing you should buy is a good quality full length sizing die. I know it's heresy but most factory chambers see little if any improvement in accuracy from just neck sizing. You're better off ensuring your F/L dies are producing concentric ammo. As far as bumping shoulders, just to add to Vamact's fine comments, because of work hardening, I use a fresh case to check every die adjustment. As dies are 7/8" x 14, 1/8 turn yields .0089" change in die depth adjustment, or pretty darn close to .001. I smoked cases for years and you can get good results. Decreased visual acuity forced me to find a better way. Now I find a cheap bushing at the hardware stoire that will set of the shoulder. Measure a fired case and you want your die set-up to push the shoulder back about .003. This method is cheap, easy and accurate. 30 calibers are easy as most use a .375 bushing. Other calibers are also easy. Just look at the SAAMI spec for the datum measurement and drill the bushing out to the appropriate size. It doesn't have to be exact, anywhere around mid-shoulder works just fine. Remember, your taking a differential measurement. I hope this helps! I think this picture is Larry's or UncleNicks. I use a standard dial caliper.
