I have a Navy Arms .36 replica that shoots pretty well. I had to put a taller front sight in it, but otherwise is box stock. Normally, I load the cylinder as full of Pyrodex P as it can be and still leave room for the round ball. Velocity is 770 fps. I took it along once while cross country skiing - shot a showshoe hare through the ribs. Worked pretty well and didn't destroy much meat.
