Sorry, but you will get better patterns using a lot less powder. Go to 1.5 drams of powder( 42 grains of FFg powder) and 1/2 oz. to 5/8 oz. of shot. Use 28 gauge OS cards, instead of the wonder wad. The wonder wad weighs too much and blows holes in the patterns. Pierce the OS cards off center with an awl and line 3-4 of them over the powder, so that the holes in the cards don't match. Then add the shot, and cover with 2 OS cards, again with the off center holes to let air out. The air separates the cards when they leave the barrel, and being so light, they quickly are stopped by air, and fall to the ground, leaving your pattern in better shape. A heavy load in a 28 gauge is 3/4 oz of shot, and 2 drams of powder.( 55 grains) Its not needed for small game( squirrel, rabbit, etc.)Read the V.M. Starr article on Bob Spenser's Black Powder notebook site.
