Gotbuck, I did the same thing (bought the BPI 3-1/2" wads from Graf & Sons.) Wish I'd bought the shorter ones, though, because I know the 1.5 oz weighed shot I'm using doen't fill it up. In fact, I hit the edge of it with my ramrod, give it one more shove to get the card into the cup, and then turn the rod over to use the smaller end to gently push the card the rest of the way onto the shot (the big end gets stuck if I try to push it into the cup too far.) How much shot were you using? I had been shooting my 50 cal barrel, and then switched in my 12 ga barrel...and got a rude awakening. It's so much lighter, and the shot is much heavier. Got a nice purple place on my shoulder!
