Just found 8# canister of the above powder, I must have bought 15 years ago, it has some data on the back of the container for .223, 7mm TCU, 30-30 Winchester, and .308. Is anyone familiar with this powder? I don't believe I used any of this powder as the seal is still intact. So far I can't find any data on the reloading of the powder other than what is on the container. My question is, is this powder any good for .223 as far as accuracy is concerned, and where should I start my loads? I'm sure the stated charge is maximum?
