I have been shooting one for about eight years now. I shoot the .451 roundball and 25 grains of Goex 3f and the accuracy is exceptional. I did buy some roundnose pistol bullets for it. They are not as easy to load and you really have to slow down or they jam in the loading ramp. Other then that they shot all right. The roundball is my bunny hunting weapon. Throw on some snowshoes, hit the marsh, and hunt snowshoe rabbits.. great way to spend an afternoon.
