Re, the carbine - at first I thought you had mounted skate wheels on the thing, LOL. Then I realized it was on a coat rack.

I started off with a .357 revolver, then bought a lever action in the same. Then a snubby in .38, and so on. I seem to have homed in on a selection of .22 equipment and .38. It's really reigned in my desire to deviate, though I understand the limitations. I have a milsurp bolt action or two, a shotgun, and I feel pretty much set. In my mind, there's a lot to be said for commonality of ammo, and "dual chambering" of .38/.357 and others.
