Shot this cannon today. I used 1.5 oz of #4 lead shot in a cut shot cup, 100 grains of loose Pyrodex, and a Carlson's .670 extended turkey choke. It kicks like a Mule with this load. At 25 and 45 yards the 8x11 sheet of paper my printed target was on had alot of holes in it. It was really windy so I only shot it 3 times and didn't count holes.I am going to wait for a calmer day and take it back out and experiment with different loads.I was helping my Dad sight in his new Nikon Prostaff scope on his Optima so I was more occupied with this. I will post my detailed results when I get more range time with it.
