Hello Mark, I use Fiocchi and Gamebore spreaders for serious sporting in my 21's. They use the same wad and are ~equivalent in performance. Either will open a pattern by 10-15% at 30"/40 yards and that's with any choke, not just tight ones. However they are much too hot for a vintage gun. I'm sure they're loaded to modern SAAMI max pressure ~ 12,000 psi. The only ones I can find nowadays are 1-1/8 ounce at 1250 fps and recoil is definitely there. Fiocchi used to make 1-1/8 ounce at 1200 fps which I much preferred but I believe they are off the market, at least I haven't been able to find them. When I shoot my Foxes with tight chokes for sporting I just use reloads with soft shot #8's or 9's for the closer birds. Actually that may be the best bet even with the 21's. Forces me to really concentrate on the sight picture I want. Frank
