I'm kind of a tightwad,don't like to spend money if I don't have to. Wonderwads are about 6 cents apiece plus the price of cap and powder can make for an expensive shot.Can a cotton ball be substituted for a wonderwad ? Just bought a lb.of Goex the other day for 20 bucks,anit that an awful price. Can't wait for the weather to warm up so I can shoot some of it up.
