I had one, now wish I had kept it, shot .75 inch groups at 50yrd as long as I could stand it 250 gr and 300 gr shot to the same point of impact at 50 yrd and 300s about 1.5 lower at 100, you can use Hornadys 50cal muzzle loader saboted bullet they are 45 cal I did not get any before I sold my barrel but heard that it solves the fragile pistol bullet problem, the thumb hole stock gives better control of the JUMP or mule kick
