Oooh, but there are so many!
I've had 2 . 41's very nice caliber. I sold one (mistake-never sell a short-arm) and the other was converted by Hamilton Bowen to a . 45 Colt-based 5-shot monster pistol. He builds the cylinders in house and you can stuff all the powder and lead you want into it. I have chronographed up to 1300 fps with 350 grain LBT pills. It's slightly painful at that level.
Most of my sidearms are . 45 Colt or ACP. Kimber SS 5" is my carry gun.
. 30-06 is my main deer buster.
. 375 H&H is my big deer buster.
. 280 Mountain rifle is my current project.
But I'm wildcatting from now on so I see a . 338/06 variation as my next do-all rifle and I'm going to build a . 17 Ackley Bee on a single-shot.
This Labor Day we'll be shooting my buddies brand new Armalite in BMG . 50!!!Oo. as well as assorted class III ordinance (223, 9, 45, 30c, etc. ).
