Haven't used it on deer, but the Hornady Custom 75 gr HPs (flat based) I bought shot 3 rounds inside a dime at 100 yards out of a Stevens 200, 22 inch factory contour barrel, with no accutrigger and a 3X9X32 Tasco scope, so I would call that accurate. So I went a bought a box of 250 bullets to work on duplicating that load. All I can say about it is it is any awesome target round for 100 yards out of the cheapest gear you can find. smile
