For example, my Hornady 308 Win. FL size die squeezes and tapers the brass noticeably more than my RCBS die.
In 308 I have FL dies from Lee(2), Hornady, RCBS, Redding, Forster, and there may be a Lyman buried in my gear stash. They all move the brass differently.
I wasn't aware there would be that much diff between brands of sizing dies.
I've never had diff brands for the same cartridge at the same time.
Good to Know - Thnx
