    I'm new to this, so pardon my asking, but I thought alloys for hard bullets were supposed to be 95/5 or so. Is the 90/10 because of the pewter or do I just have bad info? I have 1.2 pounds of 98/2 antimony and silver. I was planning on adding 8 ounces to 10 pounds of pure lead for my 45 bullets.

    Tin is not a hardener, antimony is. The more antimony, the harder the boolits.

    Tin makes the metal more pourable. You only need about 1.5% to give you a good filled out bullet.
    Tin is expensive and good bullets can be made without it but you have to cast at a higher temp and that has its own problems.

    The only time I made sure to use tin was for my 600 yard 30 caliber bullets. For 100 - 200 yard practice, I would shoot range scrap as the accuracy was acceptable at those ranges.

    I have a friend who shoots competitively and to save money he casts his own lead bullets for both .40 S&W and 10mm, 180g RN. He uses wheel weights exclusively with no add-ins. We always joke about it because his guns smoke like black powder when shot (I think he uses Clays as a powder). He has no leading issues in either of his Glocks and his velocities are not slow. The 10mm is used for bowling pins exclusively and I think his velocity is in the 1200-1300 FPS range.
