Just wanted to see who all out there preps their new brass before its first use and how they do it. I reload several cal.s but feel like I shouldn't need to prep quality brass like winchester or starline, except to chamfer case necks before loading. Also when reloading a .223(AR-15) should I FL size every time or are fired cases really a better fit that should be neck sized only ? Lemme know - Texmex
