Keep in mind that various schemes have been attempted and have failed for one reason or another concerning ammunition and it's availabliity.
One that comes to mind was the serializing of cases and projectiles, much like barcoding to track usage and presumably to limit sales. That didn't work out.
Then, formulating primer components so they would have a definite shelf life, say 2 years and no bang. That didn't work either.
Then there is a proposed limit on just how many of what you can buy in an alloted time. That might work for factory ammunition but for handloaders (like myself) thats won't work either.
Better yet is added a tax like on cigaretts and booze comensurate with the commodity, in this case a hefty excise tax. That might work. Give more revenue to the government so they can pay down the deficit...right
If I was a politician, I'd just eliminate all magazine fed rifles and handguns and only allow single shot firearms to be sold and require a comprehensive background check for all firearms bought, kind of like what I had to do to get an FFL.
That way, the Second Amendment isn't compromised and citizens still have the right to bear arms against a tyranical government, just one shot at a time.
That would also alleviate the 'panic buying' of factory ammunition and components. You don't need a thousand rounds of whatever, when you can only ignite one at a time....
Aren't you glad I'm not in Washington??
