Great gun out to 150 yards Probably killed for deer or all big game for that matter than most any other caliber. Someone who uses it all the time can kill deer to 200 yards without much trouble. I like the 170 grain bullet best unless the range is close. Like tree stand close maybe to 50 yards. Either bullet will work at close range. While its not a big bear gun, many grizzlies have been taken with the 30-30 and its smaller cousin the 44-40. Like I said though its not intended for that use anymore.
