When I first started using H322 the bottles were marked H322 G I Surplus. My guess is the stuff is being used for the bogus war going on.
That GI322 was a pulled down powder, slightly slower than the regular H-322 that was also available at the same time.
8 pounders of the GI were only 40 bucks in 1988, with no haz mat or taxes when ordered, no internet either for that matter.
