For Trap I use Magnum shot, and probably will eventually get back to Red Dot powder. Red Dot provides about the most economical load. I have been using 700X, 800X, PB, and SR7625 because I bought some caddies from a shooter retiring from Trap & Skeet. I might give International Clays a try because it is supposed to be so clean burning, though, once the large caddies are used up.
