Elvis Ammo inspired me to start doing this some years ago. As a german engineer I had to try it and it actually works perfectly for me. I hope I'll find some likeminded folks here.
Here in Germany lead wheel weights aren't in use any more, that way there's a huge supply of zinc wheel weights for free.
- I get my lead for free too, as we have to use steel bullet traps (perfect to harvest lead from) at pretty much every shooting range in Germany - .
Since a while now I'm casting zinc bullets for use in higher pressure and speed applications, where lead just doesn't seem to cut it, like real rifle bullet speeds no reduced "cast bullet loads.
I cast zinc HP bullets for my 308 hunting rifle (nominal 180gr mold casts 110gr zinc).
I cast 44 Mag bullets (nominal 240gr mold casts 165gr zinc) for high speed high loads in my Desert Eagle (no gasport clogging if someone feels the need to educate me about cast bullets in DEs) and a Marlin 1895 cowboy.
As the bullet weights are on the low side ~63% of a identical lead bullet, I had to develop a load accordingly.
I tried zinc bullets in pretty much every caliber I have, but there's just no need to go through the more complicated process of casting zinc for slower bullets I think.
My next project is developing a cast zinc load for my HK SL6 in 223.
I'm looking forward to discuss the topic with you guys!
