I read this also and the article said that these were just knock offs of Alliants red, green, blue, and unique powders. I have never tried them, like the original and I have data for them.I'm under the impression that Alliant is having to use a subcontractor to make the original flake powders for them since they lost the government contract to Radford Arsenal. IIRC, BAE won the contract, and Alliant is having them manufacture the powders for resale, and that situation isn't sitting well with Alliants management.
I just got a twitch ......that little voice said get 4 more cans of the standards while you can .........
I'd be in a fix if I couldn't have Unique , H322 and 4350 . I really need to find a shotshells replacement for the discontinued 4756.....maybe Blue Dot or Steel ......no it was better . Cleaner less flash faster loads .
