I need to talk to you about using that fancy mould. I know I have to use some lube on the sprue plate but don't know what to use.
I'm just about positive it's nothing more than 2-stroke oil.
I have several MP molds, very nice
shake with black airsoft bb's then baked and quenched
I run them through the sizer afterwords so they will be a consistent diameter and to prevent seating/feeding issues.
