I have the Lyman 452374 "Devastater" Hollow Point Mould, and can not keep the area right at the nose free of wrinkles and unfilled areas, I assume because the hollow point pin is cooling down too much betweeen casts, having to remove it and all. I will be using them in a 1911 so they need to be reasonably "right" to feed well.
I am using a Lee Pro 4 20 furnace running all the way hot with 20-1 Lead to Tin alloy. I suppose I could try Lyman #2 alloy which of course does not need to be as hot, but kinda' defeats the purpose of a HP by using a harder alloy.
Suggestions?
