For most stuff, it’s kinda pointless these days....at least for wingshooting. Time vs expense vs offerings vs performance, it just has zero effect on taking game for me....sure, I might get better patterns, but I get pretty darned good patterns and dead birds, ducks, geese, rabbits, etc....and I don’t waste time trying to make them more dead with my 12s or 20s. Other gauges, there’s a better case for it. Custom TSS turkey loads? 2-3 ball specialty buck loads? Sure. Those are small batch propositions, for low volume turkey and big game stuff. I’m not wasting time anymore for a better, cheaper, cleaner clay, dove, duck, or rabbit load. They ain’t THAT hard to kill. JMO
