BP shotgun
Yep, that will do it. I use a very similar load....two mini nitro cards over the powder and one over the shot. Works fine from my 16 gauge fowler on pheasants and ruffed grouse.
I usually load 80 grains FFg, two .135" nitro cards over the powder, 1-1/8 ounce shot, and a thin overshot card. Lately I have reduced the shot to 1 ounce with good results in trap, even at 20 yards, and noticeably less recoil.
