Interesting that they labelled 2400 as rifle powder.
Shucks, that's all I've ever used it in. Everything from .22 Hornet (jacketed and cast) to .30-06 (cast).
I'm still loading and shooting Unique and Bullseye from cans just like that (I've got more old powder than Methuselah. I gotta get a life) . Shoot up the powder and toss the cans in the trash or find a gullible collector to sell them to afterwards. If you were close by i would come over and talk you out of the HiVel#2.
