Ally to use
« on: October 02, 2018, 05:16:38 AM »
What alloy of lead/tin is used for making pellets?  When casting bullets tin helps to fill out the mold better
than using pure lead.  Danny

If memory serves, most folks use nominal casting alloy (Lead 97.5% and 2.5% tin). However, other alloys can be used which contain antimony and/or tin percentages.

I would recommend a lead:tin alloy only (no antimony or arsenic) with 1% to 2.5% tin.... The latter is available as 40:1 from Rotometals, who also sell pure lead and pure tin.... you can use pure lead, but the addition of a small amount of tin aid fill-out of the moulds.... Lead has a BHN number of 5-6, and the 40:1 mix is BHN 8....
