Gentlemen,
I was trying to make some alloy for 45-70 using lee mold 459-405 hb. Using the alloy calculator it states hunting hollow point 2%+/- tin and antimony. So I mixed up some alloy that consisted of:
-.55lb (heavy 8oz) 50/50
- 4.2lb pure lead
-10lb coww
Should be around 2.2% tin, 2.03% antimony, .17% arsenic, and 95.6% lead.
I could not get this alloy to pour properly. No matter what I tried my boolits are wrinkled and no good. They all went back in the pot.
I tried everything I could think of, more heat, less heat, cooler mold, hotter mold. Just could not get it to run right.
I worked at it for over an hour, with 0 usable projectiles. I finally poured a few ingots out to get some out of the pot, unplugged the pot and walked away.
Do I need more tin in the mix to get it to fill better?
I am almost certain I had no zinc in my coww, I cut everyone with a dull set of dykes.
Any suggestions please, I am at my wits end here! I've got 15lb of alloy that is essentially a door stop right now.....
