I've been using a 10" barrel , seems good to me. A lot easier to carry than the 14 " in 22 LR I use for squirrel . It will shoot 2-3 inch groups at 100yds , and ring the 6X6 gong at 150 yards, thats good enough for me, at least for deer. Carry it in a bandaleer , kinda slung under my left arm, works for me....good luck
