I am experienced reloading rifle cartridges. I know how to find the best powder charge, neck tension, find the lands and test for the best seating depth, etc. None of my experience seems to transfer to reloading 45 ACP with 200 gn lead wadcutters for accuracy at 25 and 50 yards.
Headspace is determined by case length, but no one seems to measure and trim their cases.
Is seating depth strictly determined by OAL or is there a tuning process?
The bullet manufacturer recommends a light crimp, I have made some dummy rounds and they set to cycle well enough. The crimp is definitely less that factory ball info.... am I on the right track?
I am used to being able to measure everything, this seem more like an art..... a few pointers would be greatly appreciated
Thanks,
John
