I have a 1891 argie mauser and am thinking of trying out reloading with alternative metals, "instead of lead" so i'm wondering if anyone out there has tried this before. maximum Penetration type of metal, vs maximum type of metal for really long distance shooting. Is aluminum strong enough?, or a solid steel? I am just trying to get any helpful thought's, or hints before I attempt on my on trial and error. My winter project to do to fight bordem here in vermont
