No, banning ammunition probably isn't constitutional either

Others are suggesting a de-facto ban, accomplished either through a huge tax, or a ban on ammunition. Oh, I’ve also seen calls to limit the amount of ammunition people can buy, but I don’t think those people have thought this through. For starters, the number of bullets used by a typical rampage shooter is about what a target shooter or hunter might go through in an afternoon or two of range practice. And most gun homicides are not rampage shootings; they have one or two victims, and a correspondingly small number of cartridges expended. Moreover, even a very strict per-purchase limit would permit people to accumulate ammunition over time.

No, the people who want to tax guns at 17,000%, or ban ammunition, or make cartridges cost $2,000 apiece, are the only ones hinting at something that might make a real dent in America’s unusually high rate of gun homicide. Except for one thing: you can’t do an end-run around an enumerated right with some sort of semantic game. Chief Justice John Roberts is not Rumplestiltskin; he is not bound by the universe to disappear if you can only find the correct secret word.

You cannot accomplish back-door censorship by taxing at 100% all profits of any news corporation named after a “carnivorous mammal of the dog family with a pointed muzzle and bushy tail, proverbial for its cunning.”
