My favorite mould is the RCBS 2-cavity. I've heard SAECO is just as good.
I've only got one Lyman, and well... did I say my favorite mould was RCBS
(I have maybe 5 or 6 RCBS moulds now ?)
Anyway, I'm cheap, so I find a clearance on a NEW 6-cavity LEE Aluminum mould in my (then) favorite .40-cal... so I buy it..
It is surprisingly easy to use, and the weight of the mould isn't a big deal cause it's aluminum...
And WOW! Does it cast lots of bullets, FAST ! Seems I need to run my alloy a little hotter for the 6-cav. alum. but now I want another one for .45-ACP. --CC
