I guess if I had to use a double in a place that requires non toxic shot, I’d use one of the alternatives. I have a Nitro special 16 that I feed Heavi-metal #6s on the Federal WMA in Sherburn county. A side note, the guy who sold me 40 rounds or so of the stuff said they were crummy loads for duck hunting, but, they kill grouse just fine.

If you don’t shoot very many a year, cost of bismuth, Heavi-metal, or, whatever, is no big deal. If you get busted by the Feds with lead shot on the WMA that is a really big deal. You might get invited to the auction where they sell your gun and truck, or, you might still be in the slam.

Best,
Ted
