Several years ago someone on TS.com was selling about a fifteen inch square pierce of metal for separating shot. All of them had the same diameter big holes so was of little use to me. What I would like is a way to separate No. 9's from say 7 1/2's and 8's. I have several hundred pounds of reclaimed shot and plan to pick up some more soon but would like to be able to separate it. Any suggestions or knowledge of known product. Thanks for your response. Jackie B.
