hi guys and gals.
so today i was pouring some bullets with my lee bottom pour pot, and my lee 457-405 mold.
the alloy is a sweetened up version of COWW cut equal parts with pure lead.
i found in order to get the mold to cast with nice crisp driving bands i had to run it really hot. all of the bullets were well frosted and if i dropped the pace, or took too long with pouring the other mold i was running in-between, it would start to round off again.
I wasn't sure if i was running too fast or too cold so i cooled the mold down and started from scratch. I ran lead through it at a good pace and watched for the bullets to have a nice fill out. once it was smoking hot with the all at about 750 they were casting well.
anyone run in to that issue with the lee 457-405?
the mold is pretty new, but had been run before and is nice and clean. i tried running the alloy slower through the bottom pour and a little faster. it didn't seem to make a difference.
i'm wondering if the new style lee molds are just a little too small for this boils design and they get cold too quick? also with the step down in diameter towards the bottom of the block i would imagine that would make for a less consistent temp through the mold.
maybe someone can shine some light on this issue.
should i just say "ah well" and keep casting hot to get the good fill out? or should i be doing something different? thanks in advance everyone!
