Me and some friends all went in and borrowed choke and spent lots of $$$$$$$$ shooting different chokes and loads. The jellyhead choke did best in our sbell and the hevy #7's was the best performers. We shot 3/4" plywood @ 50yrds and we had to dig out the pellets, so don't be scared of #7's 3 1/2 shells, they will get the job done.
