I hunt with flintlock rifles on occasion but prefer revolvers in general - especially now that my home state has essentially banned lead for hunting.
As far as sixguns go, I actually have been working my way down the power scale. I started with five shot .45 Colt loads, then to the .44 Magnum, and after a brief dalliance with the .500 S&W, have "graduated" to the .44 Special for most things. I find that for small hogs - which make up the great majority of my hunting - the Special is nearly as effective as the big boys, while carrying and shooting it are much more enjoyable. A brief conversation with Mr. Prasac has discouraged me from pursuing the .357, but it still is in a corner of my mind...
