Reloading equipment won't be enough. You won't be able to get the basic materials. In addition they'll make you a criminal for making your own.
They will try. They will encounter the same non-compliance problem as with trying to clamp down on gun owners. So far, courts have held ammo is protected, as guns are, but the grabbers of the world will always try new approaches. I know it's like hell trying to get ammo in Cali.
That reminds me, need to check the online places for my new friend. I caught some flack from some folks because my wife and I walked into the store, plunked down the cash, and walked out with it, having the NICS check take about five minutes. Called it an "impulse buy" because my state doesn't believe in that stupid waiting period nonsense. We're pretty cantankerous about that commie "daylight savings time" crap too.
I have almost zero 5.56, and I have another serious hole in my cache for .45, both LC and ACP.
