They are pretty salty in terms of price if you ask me. I don't think that they offer you much advantage over some of the cheaper shells. I like the Rio star team shells for sporting and their top trap for a heavier load. They save you $20+ per case. The Remington Gun Clubs are a bad target shell as well. I agree with Duckman in that the nitro sporting shells beat you pretty hard by the end of the day. Good luck!
Shoot 'em, and again, and again. I get a lot of reloads out of Gun Club hulls too. Not as many as STS, but enough to make it worth while to pick up the Gun Club empties. AA's - not since they went to the new design.
