lead alloy questions
Posted: Mon Jan 04, 2021 6:47 pm
Gents, I know very little about bullet casting (more like nothing) but I started a few months ago casting #4 buckshot and learned quickly how to do it and fill the mold. Not the easiest thing to do I learned later. Then moved to extremely easy 12 ga slugs. But I have all this COWW lead and a .300BLK...
So I'm going to start to cast 9mm bullets and wet coat with Hi-Tek. So if I can do that is the .300BLK so difficult? I'm going to find out.
I'm pretty sure the COWW lead will work fine with heavy subsonic bullets, but how fast can I drive the alloy supersonically without problems? Below there is a thread re: supersonic bullets and a NOE mold is linked to that uses a GC even though the bullet is coated. Will I need a gas check? Or is a better question, at what velocity will I need a gas check?
I'll get a LEE push through sizing die. Will that seat the gas checks if in fact they're needed?
By all means treat me as though I know nothing and you'll have it correct. Start at the beginning and I promise I won't get insulted but I'll thank you for the thorough explanation.
