Just WOW ! The knowledge base of this group is amazing ! Thanks to all for the input.
It's a mid 70's shrouded ejector. Excellent shape. Was my fathers till he died.
My daughter "permanently" borrowed it. lol She isn't a fan of the 9mm mini XD her husband and I bought her.
And it was "Papaw's" !
Cast some dead soft 150 swc hp's. PC'ing with Smoke's pink (just 'cause - daughter).
Probably lube anyway when I size - again, dead soft.
Lots of practice with "normal" pressure, couple cylinders hot each range session.
Again, thank you all for the input - keep it coming !
