Personally I would not reload with it. Use the powder for fertilizer, save the cans for trading. Consider it a good deed.
I'll quote another post from

"Back in the days when the .30-'06 was the premier target cartridge, HV#2 was the powder of choice. However, it met its demise when several things happened. You can take your pick as to the actual reason or reasons, but several stories have been perpetrated on us over the years.
1-HiVel#2 developed premium accuracy with corrosive (perchlorate) primers and did not perform well with the (then) new non-corrosive (styphnate) primers. Perchlorate primers disappeared, leaving only styphnate primers and HV#2 diappeared, too. Sure enuff, there is a temporal associaton here.
2-HiVel#2 was a very erosive powder towards barrels and the advent of newer, less erosive powders, spelled its doom. Sure enuff, there is some truth to that statement, too. Not long after WWII, surplus IMR/H4895, a single-base, less-erosive, accurate powder became available and the inital surplus offerings were, relatively, cheap. Cheap was good after WWII.
3-HiVel#2 did not perform well in the (then) new .308 Win/7.62mm round and it was clearly a better target cartridge than the venerable -'06. The .308 went on to become a legendary target cartridge and the -'06 was relegated to the status of a superior hunting cartridge. Much truth to this one, too.
You can take your pick as to the actual cause, but my opinion is that all three things ganged up on poor old Hi-Vel to spell its doom; it was just its time to go."
