Recently picked up 20lbs of 20 to 1, I mainly cast Hardball from rotometal in 357 and 44. Was wondering what how much tin and antimony to get it as close to hardball. Kinda new to casting and wonder if anybody had any ideas. Thanks Paul

Twenty pounds of linotype, fifteen pounds of monotype works OK.

At the very top of the screen in the black band, there is a folder marked "CBA Info". Open it up and down the list is a simple program you can use to calculate what you need to add to get 3% tin and 6% antimony, hardball alloy. HTH
