Couldn't say off the top of my head
Found it.
I'm using the Fiiochi hull and 616 primer, BP's obturator, 2 3/8" cork, 7/8oz nickel plated 7 1/2's on top of 24gr Longshot closed with an overshot card and roll crimp. According to the BP load recipe I'm getting 1345fps at 7100psi.

I've got another with the BP Z16 wad and 10z of shot, but in these older chokes it shoots much tighter than I like at 30-35 yards.
