It's all good. Burn it up.
An old friend used a 340 .30-30 for both deer and black bear (and killed a bunch of both) shooting a case full of old war surplus 4831 and the Lyman 311284 210 grain round nose cast bullet. He played the old trick of dipping the primed case into the powder, striking it level, and crunching the bullet down on top of it. (You couldn't get enough of that stuff in a .30-30 case to over pressurize- or an '06 case either for that matter.) Do not try that trick with modern 4831, I don't know for a fact that it still holds true.
I have about 30 pounds of IMR 7383 (50 BMG spotter ammo powder). Bulky stuff about like 4831. Peculiar smell due to the anti-flash additive (nitroguanidine). We call it cat-piss powder!
100% loading density and a 150gr Berry in a 30-30 is surprisingly accurate! And yes...you cannot get yourself in trouble with this powder in a 30-30.
