For the first time ever, looked around online about this. Results are the same as when looking for answers here on the "fire". Yes you can, no you can't, you're an idiot, no you're the idiot... lol! But looking in some of the bigger ML supply websites, none of them list anything plastic that I could find. I did find instances like I was dealing with, the wads melting. Guys even telling about instances where plastic hulls were melting as well after prolonged shooting. For me, it's a mute point as I no longer ML shotgun. But if I were to get back into it...
