Based on the rate of success which has been found with the 55 FMJ and the 223 in the Mini-14, I would think a mil-spec type of ball ammo would work well enough in the 6.5. For serious pursuits with the 6.5 however, I'd probably opt for something along the lines of a 140 XFB, 130 TSX, or 160 Woodleigh. Then again, one might consider what has worked for northern people and their Hornets on the big bears: head shots. A big bear would not be a big deal with a 6.5 with proper back-up assuming one was not hesitant to give the back-up proper credit (and leeway).
