You bet it is! On opening day for turkey here in Ohio I went out with a couple of home rolled 16 gauge rounds and a WWII era Winchester Model 12 choked full and sat down in my deer blind. Less than 2 hours later I had my turkey tag filled out. Dropped a big hen turkey at just under 20 yards with a single shot that almost removed her head! Those #6 shot were really effective even on a tough bird like a turkey. And the best part is that that load is the same one I use for skeet! 17#s dressed. Henrietta never knew what hit her.
