About 50 rounds for the AR-15. Went to the Indy gun show and got 8lbs of WC846. Two bullets, 55gr pulldowns and 69gr HPBT Noslers.

This powder loads like BLC-(2) and I am really excited to try it out. I have quite a few other calibers that it would work well for too. The plus side, it was $90 for that 8lbs! If I can get it to shoot well, my rifle rounds will be cut in half cost wise. Now that will be cool.
