Alliant bought Hercules powder, so the Hercules logo stayed.
The powders, of course, are totally different.
Umm, I meant that Unique and Bullseye, as mentioned, are totally different powders. Guess I wasn't as clear as I though.
Unique is Unique. 231 is HP38. Bullseye is Bullseye. 540 is HS6. 296 is H110.
Powders have been changed slightly in burning rate and kept the name--AA2 is a good example. Not a BIG change, but a change.
