100 yards with a scope, I dont shoot iron sights so I really cant say. I shot one running at 135 yards with my ML one day free hand, probably shouldnt have taken that shot but caught the back of his lungs and he didnt go far. I always look for a rest if possible. Back in my younger days a couple of buddies and me raised beagles and did lots of rabbit hunting. We started taking are 22's for rabbits, all of us got to be very good shots for sometime. It is one of those things that if you dont use it you lose it.
