I just finished off a keg of IMR4350 that could be 30 years old.I bought a new 1 pound can and loading 58 grains in a 30/06 the new powder came almost halfway up the neck.The old powder was just at the bottom of the neck.I changed from SPBT to Nosler Partition and they shot about an inch higher and an inch to the left.Not much difference for hunting purposes,and I don't know whether it's the powder or bullet change that caused the difference.
