Number of times bottle neck rifle brass is reloaded is recorded in my log by lot number...more importantly, to me, is number of times trimmed. I sort brass by head stamp. A small Swissfile making a notch in the rim at the case head in the same orientation of the headstamp at each trim. At inspection after tumble, if case has 4 notches/trimmings, crimp mouth with pliers and onto scrap bucket. If ot was range brass before I got it; ALWAYS ck for head separation before load and on the way to the 4th trim.
Straight wall brass...load til it splits at mouth. MAYBE trim to min, then it becomes blamo-ammo.
