Every boolit that filled my mold today had a little lead that leaked a third of the way around my HP lip. You can see it in the pics below. I was using COWW with 2% pewter. I used my Coleman stove to heat the lead and my mold...and keep my pin warm. It took a while to get everything hot enough to get good boolits. But once I got going it was smooth sailing.
Is there a way to adjust the HP pin tighter? I'm guessing the pin or the mold is out of round and not mating together?
I also had a little lead that came between the base and sprue plate that I could scrape off each boolit with my fingernail.
The sprue plate was pretty tight...do I need to tighten it down more to fix the excess lip around the boolit base?
It's almost like the lead was filling too well and trying to seap out everywhere it could.
The box on the left had dimples around the HP so I culled them. The box on the right...I had to lightly scrape the little overflowed lip off the HP area of every boolit and lightly ran them across 1500 grit sand paper. They look good now but it was alot of BS.
Is there a way to adjust my mold so I don't get the overflow burrs around the HP lip and base?
I did notice a crack in the new HP pin handle but I'm sure it had nothing to do with the sealing issue
