Core Swage Dies

[LC Smith]

I understand that Core swage dies made for harder alloys than lead have different size bleed holes.  Does anyone have one of these?  How different are the dimensions?

I have several dies that have different size bleed holes, but I don't believe any of them were made for lead alloy swaging per se. This would have to be a speciality order for sure as the die maker would want to know exactly what mix you planned to use. While the Corbins and RCE companies claim their thick walled dies can be used for lead alloy, I believe they are talking about alloys below the BHd of wheelweights ( ww in themselves can have hardness well above 11 eventhough 11 is what most writing claim WW are ). Swagging with unknown or non-certified lead alloy is a real gamble.

My core swage dies all have different size holes in them and some have three holes.
But the hole that penetrate the die wall are pretty uniform in diameter except the counter bored hole on the out side of the die.
You need enough back pressure to make the lead or lead alloy flow.
If the bleed off is to much the bullet will not fill properly.
My one hole dies will extrude a .093 diameter wire and the three hollers .063.
