Tin + Lead vs. Tin + Lead + Antimony - Gunloads.com
Unfortunately, with the 9mm harder really is better. You need the Antimony. Like jsizemore above, I use 2% tin + 3% antimony + 95% lead. That is pretty close to Clip On Wheel Weights with 2% tin. You can't do much better! My rule is 25:1 Lead/Tin = Hollow Point Handgun Bullets. 2, 3, 95 = All other Handgun Bullets.
How does antimony improve lead-based castings? - Vulcan
The use of a little antimony in castings will help material flow so it acts to improve the feed into a part compared to pure lead. In machined or structural products, antimony adds rigidity to the design. Pure lead acts like butter on a warm day and the use of antimony will stiffen the alloy to allow machining to take place and keep the part ...
