I've been reloading Winchester hulls with S1000, W209 primers and CB0178 wads. 7/8 oz. with 18.3 grains of S1000. Accurate says this load is 1200 fps at 6000 psi. On primers they give this as Win/Rem/Cheddite. This is a nice soft shell that patterns really nice with 6% antimony lead. Guess I'll stay with this for now. Looking at all the data presented I might try the Remington primers since they are in the recipe and might be a bit softer if anything.
