Great read, and explains why the SAC neck/shoulder bushings work so well.

Thank you! Great info

If you're going to touch each piece of brass anyway, you might as well seat bullets with 21 Century Hydro Press and LE Wilson in line seating die. It will effortlessly seat each bullet to .0005 every time. You'll also find by using it who makes uniform bullets and who doesn't. The 21 Century press will let you know how much neck tension your bushings and mandrels are providing, and make tuning neck tension way easier.
