Things are feast and famine here. Last week I was on the interwebs quite a bit for the job, and was able to have some extra tabs open to watch the various sites (Scored some Alliant powder this way). It appears some powders are becoming available but the sites are shutting down the search functions so you have to manually browse.
Locally, one store went for two weeks with nothing, then 26FEB they got two cases of each primer (SPP, SMPP, LPP, LMPP). It was like someone kicked over an anthill in there...they had a ticket machine (think the deli at Walmart) and were calling numbers....started at 1215 hours - out at 1345 hours.
