When you fire form for your chamber does it take more than one firing? Should I fire form till I get a little bolt resistance? I'm trying to set my die up so I can shoulder bump like .002 and need something to start with...Thanks
For a standard case or wildcat?
Twice on a wildcat to get going - IME
Regardless, I adjust my sizing die for every brass cycle (use die shims myself). Some cycles the die setting may stay the same, and other cycles not. Each time I load a case, I start by measuring the before and after, and adjust the die to my desired criteria.
