I've said it before and I'll say it again, unless the gun is damascus and no more shooting than you do out turkey hunting, use 1 1/4 ounce 3 3/4 dram cartridges. Turkeys are tuff, these little powderpuff shells are going to fail you eventually. You might kill 10 birds in a row with them but then when that one gets up and runs off your going to be sick.
