Tamid,

I have done the sort of load you are talking about and got tons of plastic. Amazing amounts. But I know other folks that would confirm what you say. So there must be something more involved. Either your wads are different material or your shotcups are different plastics. There is a trick there that we aren't fully grasping. Your post makes me want to try again, although I'm mostly moving to all fiber wads for hunting, if I can.
