Yes, indirectly, by driving up demand; not by restricting supply.
My understanding is that the military has its own source for ammunition (e.g. Lake City) that is separate from civilian manufacturers. Having said that, I’m sure our current Fed government is at least indirectly responsible through stoking fears of confiscatory taxation, confiscation, etc.
I also think (and my range experience confirms it) that a lot of ammunition is being expending via the “SWAT teams” that every Mayberry police force seems to think is ABSOLUTELY NECESSARY.
