At the risk of guys with good memorys, I will confess my error. I went and casted with several moulds and got melted polyester? on (mostly) the outsides of all of them.Using an old bathmat? that I used to use on shooting bench to rest an arm on. Today, I was vexed with some lead smears but I stayed on top of that. This stuff was insane when cooled off. Started with #1 and they look ok and got, fine tuned up, to boot. What a nightmare I usually look after my babies better. The boolets are really nice, anyways. I have a Pelican type case with lots of VPR? paper inslde and they stay very well and no oils. If ever for sale, they will work fine, if scratchy, outside
