I will give you Doc's "pet" load he gave me. I am using another but it is not what most will want to shoot.
100 grains of Black ffg, 2 yellow under shot wads tamped down HARD, White shotcup with 4 petals cut 1/2 way down the cup, 1.75 ounces of nickel plated shot (he gave no shot size), and one Wonder Wad over the shot. He claims 95% patterns with the first shot, then less as the barrel dirties up.
