Replacement, thanks for the information. None of the shot is magnetic. It doesn't look like lead. It is shiny as a dime except for maybe twenty pellets. The pellets don't even look like the same size. It looks like a duplex load, but of what material? Federal answered an email from me last year so I may give that a shot. I'll open a shell and try to crush some pellets. I didn't realize I knew so little about shotgun shells. Actually, this discussion is a bit off topic. We were trying to verify Markethunter's suggestion that steel shot could rust under adverse conditions. I have been no help since this shell doesn't contain steel shot. Thanks again.
