RE: Hunting revolver - 6" or 8"+???
To me, a handgun has to be a "handy" weapon, not some long bbled, scoped short rifle... I carry my handgun in a shoulder holster, and that means i like a 6" bbl... I can hit well enough with it, further away than anyone should be shooting at a biggame animial, so i just don't need a longer bbl. I've taken moose, deer and ect. with my S&W M-29 6", so i'm not just BS'ing here...
Just practise, practise, and then practise some more!!
