I shoot a Charles Daly 20 gage field model with an Undertaker choke, at 30 and 40 measured yards it can almost shear a tukey's head off with 2.75" shells down to our state minimum #7.5 shot size. With a full Remchoke it does almost as well, especially with #6 shot. It's plenty of gun. Hevishot is overkill in my book, you don't need it.
