If you go to the Hodgdon reloading center online, they have recipes for Cheddite hulls. A lead 1oz load with Cheddite hull; 18.1 grains of Clays; Cheddite 209 primer; and GU 1225 wad. This gives you 7200 psi and 1180 velocity. However I do not see any recipes to use with WW 209 primers.

Perhaps others will chime in if there is any reloading data in other reloading books. I always refer what the powder manufactures recommend and I do not vary components especially for these older SxS stocks and steel / Damascus.
