Most likely it IS temporary. Once things settle down (once whatever legislative changes to be made are better known.....and the rumor mill slows down somewhat), the supply situation will likely improve. Perhaps then the hoarders will stop their a-hole behavior. Prices, however, are another matter.
I would add that, despite the insane level of speculation now extant, I consider it highly unlikely that reloading supplies will be subject to legislative sanction. Firstly, reloading does NOT figure into any of the criminal activities (i.e., mass shootings) that are driving the hysteria-based rush to increased regulation. Second, I doubt that people like Feinstein even understand the concepts, for the most part....so, reloading is probably not even "on the radar".
