Those (Lyman Dev) are testy little molds, at least the 45 cal I have is. This is my first MP mold and first brass type.

Merry Christmas, been casting for a quite a while and recently purchased a Glock 40. I ordered the 2 cavity model.

Anyone tried this MP mold in 10/40 ? Use a no lube groove type in your 10mm ?

I also will be trying my hand in Hi-tek coating as this is a NLG type.
