I just got a 4 cavity brass from MP for 45 ACP on the H&G #68 design. Haven't used it yet but I have to say it is the nicest mold I have ever seen. Fit and finish is amazing.
It is a straight mold with no pins.
Do these things actually have to be heat cycled?
I have read a cotton cloth with a very very small amount of synthetic 2 cycle chainsaw oil is the ticket for wiping off the bottom of the sprue plate and the top of the mold (leaving boolits in it) stops lead from sticking. Also very sparingly to lube the alignment pins.
I cut a fair amount of firewood and have synthetic chainsaw oil around.
