I use it lot. Forget the cost, use ITX, or "nice shot". It's pretty close to lead, loads like lead. Cost, well 6# of ITX is about $159.00 dollars, "nice shot" is about $196.00 for 6# or so. Both will be higher or non-available later. If you buy them loaded, they are about $3.00 a shot. Don't miss! People talk about to costly, etc. If it's feel like that, shot steel. I won't with old doubles, and that's what I like. The heavy shot, or HD shot is NOT the heavy shot of a few years ago. It was like 13 weight, lead depending on antimony, is a round 10-11, much like "nice shot", ITX. ITX makes a hard copy. See Professional reloading, or Ballistic Products. Both standards can be loaded without cups, with a fiber wad, a cup might make them hold pattern longer. The HD's I would be hesitant to use without one, and maybe a mylar wrapper to boot!
