I loaded some 308 last night
Your picture shows a bottle of IMR 4320. This is a kind of neglected powder these days, but one I like. One of my favorite loads for .223 in bolt action uses 4320. It meters very nicely because the kernels are small for stick powder. I'm still using a supply marked "DuPont" because I got an 8 pound caddy one time but now I'm down to my last pound of that. In the meantime, I've bought a few more pounds of newer IMR 4320 to have on hand. You never know when the turds are gonna discontinue your favorite powder. 4320 is one of the few powders available today that has been in production since the 1930's.
