It is my opinion that Hercules/Alliant were selling their powders to the US Army (Iraq and Afghanistan), that they neglected the civilian market because the profit margin was so high. At the time, the Military paid whatever the ammunition vendors wanted. They had to because the Army ammunition plants the WW2 generation built for surge capacity, were all sold off by the 1990's.
Unfortunate for Hercules/Alliant, when shooters went to the store and could not find their favorite Unique or Bullseye powders, what they found instead were very acceptable substitutes. The Bullseye shooter's I know, when they went to the store, it was out of Bullseye, but Titegroup was in stock. These guys tried Titegroup and liked it. They developed excellent loads with Titegroup and are not in the mood to switch back. Once you get your gun set up, establish your zero's, build confidence in your load, chasing the latest and greatest powder is a fool's game. New shooters who developed Titegroup loads have no memory of Bullseye, and are going to stick with what works. I think that also happened with Unique. My Unique dates back to the 1980's when I bought cases of 1 lb bottles. I have used it in 32 S&W Long, 38 Special, 44 Special, 45 LC, 44 Mag, and 45 ACP. This powder is just outstanding in 44 Spl and 45 LC, I have yet to find another that shoots as well, and I am using thrown charges. Unique was a staple in the 45 ACP for Bullseye Competition, it was just behind Bullseye powder, but when the store ran out for ten years, shooters moved on.
