Hi all, back from a lengthy hiatus.
I've been reading a bit lately about people starting to cast with zinc to create bullets that can be run at jacketed speeds and do not need gas checks. An application I am looking at specifically is casting for 8.6 Blackout to make some cast supers that won't spin apart that would be good analogues to all coppers for inexpensive target practice. Other than newer zinc wheel weights, I'm not sure where else you would get scrap zinc, then pennies hit me. Legality aside, has anyone tried to melt modern pennies (97.5% zinc) and cast with them?
