Well, damn, this is not good

The company, which produces weapons ammunition sold on Palmetto State Armory’s website, operates alongside the armory’s production and distribution at the facility, but are separate brands. John Roberts, an attorney for the company, told The State that workers for Palmetto State Armory would not be impacted by the closure.

The company told DEW that the closing was “due to catastrophic supply chain constraints of raw materials necessary for production.” Roberts told The State the closure was a result of a gunpowder shortage.
I've known about the troubles for some time, but I'd thought the companies involved had found supply workarounds for the materials.  Apparently not, or at least not as well as I'd thought.

I can tell you that after Alliant cut off propellant sales for reloaders so they could put all their production into the corporation's ammo companies, they've started selling some again; Bullseye and Unique have been showing up on the market again, which made me thought that the supply problems had eased.

Isn't this all just so much fun?
