I also use RST's Nice Shot, excellent results. For hunting, I always carry nothing but the non-toxic shells, whether its RST's Nice Shot or Kent's Tungsten Matrix, they perform better than lead. With the amount of shooting I do while hunting they are more than affordable and, more importatntly, I just don't want to run into trouble with all the various and sometime confusing regulations out there today.
Here is RST's web-site information and you can order directly from them with fast service.
