Hopefully this is of help to a few peeps.
I know a few guys here have been struggling to find Alliant powder for ages now. Looks like NIOA has some supplies in ago though.
If you're not subscribed to the SSAA magazine... They're flogging it with ads for powder again after being MIA for ages.
Anyway, just FYI so people can contact their LGS if there still without their powder.
