I don't know if this is the kind of info you are looking for, but I load up bismuth in my 10 ga. It's a #3 frame hammer gun with full/full chokes and .793 bores. 2 7/8" chambers. In brass hulls I load 4 1/2 drams of FFFg Goex, one 1/8" nitro card, one 1/4" dry felt wad, one 1/4" lubed felt wad, 1 1/2 oz of buffered bismuth shot. All wads are 9 ga. At 40 yards I pattern 81% out of both barrels with this load.
I've never had this load chronographed, but going by some of Sherman Bells' tested loads that are similar, mine is probably in the 1300 fps range. All I know is that it consistently kills ducks cleanly out to 50 yards with #4 shot.
