The government has defined nitrocellulose, a deflagrating explosive, as a high explosive.
This makes anyone who creates ammunition subject to rules that are impossible to comply with. Fortunately the government has also issued an unprincipled exception, telling people not to worry about it. Just go on handling nitrocellulose as the deflagrating explosive that it actually is, and, wink, nod, we will not prosecute you.
But slowly, over time, unprincipled exceptions always go away. This is a back door criminalization of private ownership of guns. A few years down the line, they will start enforcing this, and say, “Oh, we are just enforcing laws that have been on the books for a long time, but widely ignored.” And private gun owners will find it strangely hard to legally buy ammunition. “Hey, the state has not banned your guns, nor your ammo, just banned anyone who makes ammo for your guns. And this law has been on the books since forever. They are still allowed to make it, but they have to make it safely – except that no one can figure out how to make it safely.”
Of course people who make ammunition for law enforcement and the military will get a continuing unprincipled exception, but people who make ammunition for private customers will not.
Then again, the way they are cutting the balls off our police and military, I would not have a lot of confidence that the military will continue to get ammo either. They banned mines and cluster bombs by a similar back door law: Our government passed laws against our military that could never be complied with, issued an unprincipled exception that allowed mines and cluster bombs, then the unprincipled exception somehow slowly faded away. Meanwhile the Soviets continue to use cluster bombs with devastating effect.
I cannot see any sane reason for banning cluster bombs other than that in the many proxy wars where the Red Empire of the Bases backs one side, and the Blue Empire of the Consulates backs the other side, cluster bombs were blowing the hell out of the State Department’s proxies.
