.45 muzzle velocity
I have a .45'' percussion kentucky pistol replica and was wondering what the muzzle velocity is on it shooting a .44'' diameter ball with a .10'' patch using 20 grains of ffg powder? i believe it has an 8'' barrel.
i dont have a chronograph and was just curious. thanks, the rifleer |

My Guess
With real black powder, my guess 750 fps 30 grs. will give you 1,000
