If you use the Cutts spreader choke in your 12 gauge, you won't have to mess with your wads to get an open pattern. Your pattern through the Cutts spreader will be about as open as you could wish for. OK, some day I'll throw some patterns to prove what I am gushing about. So far, all I've done is shoot tens of thousands of shells at skeet birds through Cutts guns with good results. To be honest, I agree with Sam on the .410 Cutts spreader patterns. They are tight.
