Locally, powder is hard to nearly impossible find. Anything really: brass, powder, primers, bullets, reloading equipment. I suspect store employees & friends of the store employees get first dibs.
I've been able to get H1000, H4350, Varget, & Retumbo online in 2020. Only because I happened to be on this site when someone posts where XXXXX powder is available online. Nothing else matters when I see that post. I just get to the website as fast as I can and order it. Just buying what I need for a couple of new guns (not hoarding or reselling/scalping). Partner up with someone and let them know your wish list items and look out for each other. I haven't been able to buy any primers this year but I've been able to trade powder for them locally. I've been able to help a couple people out along the way and that feels good.
I've tried to sign up for email notices on all the major websites but I never seem to get them.
