While we are waiting for either (a) the other shoe to drop, or, (b) the panic to subside, there are a number of things you can be doing besides being frustrated that you can't immediately buy what you want as far as firearms and ammunition.
How are your long-term storage food stocks? There is no panic in that market -- yet. See to your logistics. If you are temporarily stymied on bullets, look to your beans.
How's your fitness? Take out your frustration by getting in shape.
See to your marksmanship skills. Go to the range, attend an Appleseed shoot, practice and then practice again.
A lot of us have projects sitting to one side that we haven't finished -- reloading sessions that we've been putting off, an unreliable weapon that needs some TLC gunsmithing, ammo in the box but not combat packed in bandoleers, stripper clips and ammo cans. Finish up what you can.
Don't leave all your eggs in one basket. Cache.
Train. Organize. Confront your county sheriff about whether or not he will be enforcing Fed diktat or interposing himself between the people and the tyranny.
Whatever you do, it's better than gnashing your teeth in frustration.
