Whatever I'm carrying, usually a 10mm Kimber, but might be a Ruger SS, 22 lr or 22 mag. Or a Marlin 917 HMR, (I think this may be the most fun gun I own), or my Excelarms 22 Mag semi-auto, with the new plastic tipped Remmys it's amazing how accurate and hard this thing hits. My Savage 12 FV with either it's 223,22-243 Midd., or 260 AI barrel in it makes a fine small game gun. Heck, I guess all my guns are my favorite small game guns! lp
