Tac: I misread my own data, but I am still correct.
My mistake was in thinking the gun was .36 cal. However, wirh a .451 bore(44 cal.), an 8 inch barrel with a 2 inch cylinder, you have 10 inches, more or less to burn the powder in. That amounts to 18 grains. Its 1.829 grains of powder per inch of bore, pursuant to the Davenport Formula.
Use a filler above the powder and then seat the ball down below the top of the cylinder. That will compress the filler and insure a good burn of the powder charge. You get more than enough velocity, the best accuracy, and plenty of smoke and flame with this load, without the recoil, and beating of soft metal parts that comes with the heavy loads described.
Too many shooters of replica revolvers are trying to turn their guns into .357 and .44 magnum revolvers. The designs of these revolvers, and the metal used to make them is NOT designed to take that kind of load. I too have sinned. :shocked2: :surrender: :thumbsup:
