Those square "super sticks" are the very old ones. New ones are round but ive never seen them for sale anywhere. They either paid the "fee" or the Hodgdon patent expired.
A few people on the forums have tried to contact APP with no luck. The plant in Colo had an accident 4ish years ago too. Might have been another since then but im not sure. So any bets on what powder he chooses next to promote? It sure dont look like its gunna be a APP powder.
His Youtube link for the new pellets is gone too? Says unavailable when i try to play it.
