I'm shooting 3.5" heavy shot #5, and 2 gobblers at 40 steps were hammered, both had a chunk of their beard missing and feathers blow out 5 ft behind them. One looked like he had been shot w/ a rifle. I'm using the HS strut Undertaker choke. I think it's brutally lethal, and i'm not sure how much damage can be done to the gun shooting a handful of them during turkey season...
