I have a bunch of powder from some WWB .223 that I pulled and was wondering what it is. I wouldn't mind reusing it for .223 FMJ if I could find some load data for it. Worse case I guess I could just weigh it out and divide it by the number of bullets I pulled, but that would take a while.
What kind of powder in Winchester White Box?

The ammo manufacturers don't necessarily use canister grade powder that we use. If you weighed the powder charge from a cartridge and know the bullet weight and velocity, you can work out a safe starting load based on the data in the loading manuals.
