I have a custom aluminum 4 Cavity mold, made by Accurate Molds. 32 Cal. 60 grains SWC
i an getting a line around 3 sides of the bullet. At first I thought it was indented, I contacted Accurate Molds and got a very short reply that I was not casting properly and the lead was not filling out properly.
this was the same on all 4 cavities.
I get this line, at temperatures from 650-1,000 F. It also hapens at all lead types from pure to very hard foundry lead. I have casted lead for many years with no problem.
after a very careful inspection of the bullets, it is not an indentation, but a very slight out filling.
when I size the bullet thru a die the 2 sides below the nose are pushed in, and the line on top gets pushed in when the top punch pushes the bullet in the die.
but I am left with a line on 2 sides of the nose.
is there something I am doing wrong, or is the mold at fault.
thanks in advance.
