Sounds good! The normal Lyman mould runs .690" on the slugs I was sent and 506gr. in WW alloy. They do fit nicely in a WW red 1 1/oz. field wad, leaving enough room for a decent powder charge.
I haven't got to work - yet - on my loads, but since obtaining a pound of AA Steel powder, I am champing at the bit --- a bit. I need to borrow my bro's roll crimp tool.
