Curious if anyone has used this and results. Friend has a bag of what looks like number 12 or 14 size copper wire cut in diameter length sections. Round in diameter but with cut ends, looks like wire ran through a chopper of some kind. Guy that he got it from said was copper shot to meet the no lead laws? He is going to load in shotgun shells, not a muzzleloader shooter. First I have seen or heard of like it? Would be about like number 4 to 6 shot in size just guessing.
