Hope you don’t mind me posting this on your thread Tim?
today I tried a 10%linotype to 90% lead alloy for both the hollowpoints and the Lee 180 gr RN moulds.
i had initially tried 100% lead ( or near as damn it) and it proved far too soft to go through the lubrisizer without the nose section squishing down, I the case of the hollowpoint to 0.325”!.
A harder alloy is then needed to avoid deformation and so the 10/90 link/lead was tried.
This alloy cast very well and was a little harder than the pure lead meaning the lee 180 bullets came out ok but the hollowpoints still squished out.
I think this is to do with the gas check which being copper needs more force to size than a pure lead boost would.
