Slightly OT, but...
I make gun purchases with case head in mind. .45 acp, .22-250, .308, .30-06, as every handloader here knows, the list goes on...I know it's weird, but I don't have to worry about shellplate size or primer size. I'm waiting for a .300 Win Mag equiv. but with a .30-06 head...mabye I'm dreaming.
