i was recently given 100 pounds of eagle shot magnum shot and I came across the opportunity to swipe 140 lbs of lead flashing for free, so I did :)
I figure with all this lead I would like to cast for my 45 raptor. The question is, if I mix both together with a 1-1 ratio will I have a strong enough alloy to push bullets about 1800-2000 fps range. I am also planning on powder coating. I know magnum shot is 5% antimony so I should get about 2.5 with the mix. I also have about 5 lbs of pure tin I can throw in, so my goal for this is about 2.5% antimony 1-2% tin the rest lead. Based on some calculators that is about BHN of ~12. So to restate my question, would that alloy cast into boolits and powder coated be sufficient at 1800-2000fps range.
These rounds will only be for plinking as hunting here in the people's republic of kalifornia requires a solid copper bullet.
