Is there any advantage to shooting a 20 gauge vs 12 with lighter loads? I am interested in reloading heavier non toxics and also have been looking at new shotguns. Seems like having a heavier 12 gauge and shooting lighter loads of heavier shot would be best unless I am missing something? Heavier 12 gauge shooting 1oz is going to kick less than a 20 gauge launching 1oz and larger barrel diameter would lead to better patterns? Appreciate any feedback on this as I don't want buyers remorse and I do love the feel of some of the 20 gauges, they re some handy little blasters.
