Sounds like a treat!
: I don't know how the smokeless loads compare with black powder in the 4 bore, as in 12 bore guns, smokeless loads kick only about 1/2 as much as the heavy 7 dram BP load. A 14 dram 4 bore BP load produces more than 200 pounds of recoil in a 20, or so pound gun. Not for the timid, or perhaps one who wishes his retinas to remain attached.
