I had one for two years, and used it successfully for deer (rifled slug barrel), upland game (standard barrel), and turkeys (short turkey barrel). Only issue I had with it was that it wouldn't run in cold weather, like below about 15 degrees, no matter what I lubricated it with. I even tried graphite, RemOil, and the Browning silicone spray lubricant, and it would still get slow enough to jam at least occasionally. Loved the feel, fit, finish, and balance of it, though.
