You are right about the dismantled shells but as far as finding 30% copper, I have loaded several bags and have not seen copper. I was told they are getting their program more refined. So that being said, it's possibly why I see no copper in the new bags I have been getting. I have used it back to the 27 yard line and seen nothing but smoke if I do may part.This is from all the reject shells or bad lots. Sold to another company that dismantels them and sells and shot and primers, they do it to larger shells too. Lots of prairie storm shells, which is where I get a good portion of lead for games loads, it might have 30% copper plated in it though. Usually you can find a small amount it the 7.5 too but very minimal. Its good shot for 16s and double, works just fine
As far as antimony I have no idea. The shooters I have sold it to including myself really like it. Smokes targets anywhere on the concrete and beyond if you do your part.Again…..
What % antimony please???
