I'm interested in people's thoughts on suitability of Rotometals "Hardball Casting Alloy" compared to Lyman #2. According to Rotometal website...
Hardball Casting Allow = 2% tin, 6% antimony, 92% lead. Brinell hardness about 16
Lyman #2 = 5% tin, 5% antimony, 90% lead. Brinell hardness about 15.
The Hardball Alloy is $0.32 a pound cheaper. I have been using ww for 30+ years in pistol and revolver loads with complete satisfaction. The ww are now harder to find in WA. state, since they have apparently been legislated out of existence for new installation. So all I need is something equivalent to ww. From what I read, 2% tin is enough for good castabilty (filling of fine detail in mold). Do others agree with this statement? Is it worth paying extra for the Lyman #2 alloy?
Thank you for your thoughts.
