Ok so with my RCBS Die How do I know how much crimp? With the .45 acp I know if it fits in my shell gauge it is right and I can measure it, but not sure how to tell on the .223 with or without cannelures.
I tested a few and they look good, but I have no idea how much I put on them a half of turn past touching the case mouth.
Also do I have to trim all the cases in order to crimp the same everytime? I guess I do not know if my cases are all the same length.
