31-110E Accurate mold

[bbs383ci]

has any one used this mold for 300 blackout ar-15 platform.

i am wanting to use these for plinking rounds, powder coated also.

i am new to rifle casting, will i still need a gas check if i powder coat. if so do i set the GC then powder coat it all?

Or should i go with the 31-110MG if im powder coating?

Thanks.

31-110jz add a GC if you are pushing hard. You will have to seat them long.

I can't help with the details about the boolits. I will say that when I use has checks, I seat them by passing through my NOE sizer, THEN powder coat. Back through the sizer again.
