Well MY AR-15 takes .223 or 5.56, 7.62x39, 6.8 SPC, 300 Blackout, 9mm, and one or two others that I am probably forgetting. So there. ;)

Well, aren't you just the over-achiever! :)

Mine only eats some of the ones you mentioned, and I like the fact that I can get the .300 Blackout in good subsonic loads. I'm interested in something big-bore, .458 SOCOM perhaps?

Btw, given your screen name, I have a .44 Mag carbine that is just a tack driver at 100 yards... Not to mention a couple of revolvers. Love the cartridge!
