Antimony?

you will need a cutting torch to melt antimony, then cut it with lead and the melting point will lower, I have a 20 pound ingot here that I can heat up really good with propane but not quite melt, the more antimony and tin in your lead mix the higher the melting point and hardness will be
 
Got a response from Canada Metals about the antimony, $20.00 per pound, minimum order is $250.00 plus taxes and shipping. Think I'll put in an order in a couple months and will be good for many years with all the tin alloys and the shot that I have now.
Going to mine the backstops at our range when it warms up then cast some bullets to check for hardness and add antimony and tin till I get the hardness I want. Have a toaster oven in the garage to heat treat the bullets. This process to make cheap bullets sure has cost me a lot of money lately! The end result will be well worth it though.
