What MD said is true. Folks who shoot competition burn far more powder than hunters. Last time I bought an 8lb was in the 80's when I used to run H4895 in my M1 for High Power. Just checked my inventory and have over a pound of 4320. With the few cartridges I use it in with loads long since developed, it will last me the rest of my hunting life.
Now if I can just find a pound of RL26...
