Unfortunately I think there will be panic shortages. People like those of us on this and other boards represent only a very small portion of the gun owning public. Like the last rush it'll be enhanced by the opportunistic scalpers who make reselling part of their livelihood. One only has to look back the shortages of the 90's (Clinton AWB), 2008 (O'Bama election) and Sandy Hook to realize that the majority of people do not learn to be prepared.
I've seriously contemplated some overstocking, to use as investment, but i'm not sure I really want to deal with the hassle of other people. Plus I'm betting NJ passes an FFL Required law for ammo sales in the not too distant future.
