Recently nitrocellulose had been reported in short supply and Alliant had suspended powder production - which actually was being done in "spare time" at the two US making facilities being operated by General Dynamics. Now with this ~ threefold increase in 155 mm shell production, it remains to be seen what effect it will have on reloading powders and even loaded shotshells by the familiar makers. Net, my take for many of us is: buy what you want while you can.

Add to this the amount of nitrocellulose the Russian Army has and is consuming on the other side of the war that is no longer available in world markets for sporting use.
