I still have about a gallon and a half (out of 5 gallons originally purchased) of WWII 4831 that I bought for $1.50 a pound in about 1968. It still smells sweet and shoots well.
I used 62.0 grs with a 130 gr bullet in various .270's over the years with no issues until last year, when I got an apparently soft batch of Remington nickel plated brass. I experienced difficult extraction and ejector marks on the case head. I think that I would have had problems with any load with that brass.
In a 24" barrel I was getting just about 3200 fps with 62/H4831/130 NP. Now that I am old, I have backed off to 60.0 grs of 4831 with no damage to my ego so far.
