Therein lies a well nigh perfect hunting combo! Out of curiosity have you targeted it with ball in the smoothbore barrel?
Yes!!! Almost dead on at 50 yds with a .600RB, 70 grains FFFG, and .010" patch. Maybe just a tad low.
Rifle barrel = .500 RB, same 70 grains, and .015" patch. Deadly at 50! Just a bit high. But Hold at 6 O’ clock and It will make pork!
