Dec 23, 2019· Antimony is used as the primary hardening element. Pure lead is the cheap part; it has a Brinell hardness if 8.6. To illustrate the formula: Let's say we alloy pure lead to arrive at a composition with 4% tin and 4% antimony. So, Bhn = 8.6 + 4(0.3) + 4(0.9). So this alloy would have a Brinell hardness of 13.4.

Most shooters will tell you, that it matters very little for 16 yard targets, but it matters much more the farther you move back in handicap. Many shooters will practice will low antimony, but shoot matches with high antimony loads.

Antimony (Sb) – Properties, Applications

Jul 28, 2012· If you mean you found pure lead, add linotype, which is 11-12% antimony and 3-4% tin. I will mix 3 parts pure lead and 1 part linotype, which should give you about 3% antimony and 1% tin. This alloy should be similar to wheel weight alloy. ...

Jan 25, 2010· 6% Antimony 2% Tin Saeco Hardness 8.5 to 9 Brinell Hardness 16 He calls these hard cast bullets, I've read the article from Shakey Pete's Shootin Shack concerning cast bullets. His article say's that most commercial suppliers use a 85% lead, 5% tin & 10% antimony and that they're to hard to slug up properly in anything other than maginum loads.

Who Puts the Hardest Shot in Lead Target Shotshells?

To obtain maximum hardness, a minimum of one to two percent antimony is required in addition to a trace of arsenic. Arsenic is the catalyst. Heat-treating cannot work without it, regardless of the amount of antimony or other trace elements present.

Shot Hardness. We come now to the hallowed ground of shot hardness. The Sporting Arms and Ammunition Manufacturers Institute (SAAMI) tells us that "lead shot pellet hardness is established by the amount of antimony alloyed with the lead in the pellets and is varied by the manufacturer depending on the purpose for which the shotshell is designed."

How much does antimony/tin increase hardness | The High Road

Dec 11, 2018· There has always been discussion here about what is the hardness of a lead mixture with certain amounts of antimony and/or tin. I don't have a simple formula for that. Some years ago, I got a bunch of almost chemically pure lead (roofing lead). I also had pure tin and a bunch of monotype with a set quantity of antimony in it. At the time, I also had three hardness testers (SAECO, Potter, and Lee).
