I shot a deer from a stand once at 20 yrds with a 8 3/8 bbl .357. 20 yrds aint bvery far but it was amazingly underpowered despite using full power ammo. I am now the owner of several .44 magnum single action guns and thats the smallest I would recommend for anything larger than a squirrel. For concealed I use a 1911 style .45 auto. Good luck on your hog hunt.
