I use a 10 gauge Remington SP-10 Magnum with Remington 3 1/2 inch magnums loaded with 2 1/4 oz. of #4 lead shot. I use HD shot for waterfowl hunting but it is hard to justify the expense of HD shot for turkey hunting while it is still legal to use lead shot in most locations. In my case I hunt in Northern California where lead shot is permitted but if I were to hunt in California Condor range in the mid and south sections of the state I would have to use non-toxic shot for turkey or any other upland game as well as waterfowl.
