In this pistol having a 66" twist, .535" bore diameter barrel, I used 55gr. 3F GOEX, a 10 ounce denim patch and .526" ball.
This load had a healthy recoil to it, but shot well. Less powder shot poorly due to the piece of rifle barrel used, but with this
load, it would do 2 1/2" at 50yards from a rest. The rear sight is simply the domed head of two pins set into the tank at the
breech end of the barrel.
I filed the tapered octagonal breech and then used my old Optical Company lathe to turn it round, + the wedding bands and
gently swamped shape. Originally, it was a 1" straight octagonal barrel to start with.
