2 Bore SxS Jones Underlever Black Powder Cartridge Rifle: S&H Brass “ diameter cast round ball Goex FFg Black Powder W209 Primer These are the first couple of shots at a 500gr FFg Black Powder charge. I am just starting the load development with these first couple shots, they are both from the left barrel, I'm working to develop a common load for both barrels at this point. Regulation will come later. For more information on this project please visit: or to see the documented build log please visit:
