In 1791, the Second Amendment was written.

In 1847, the bullet was invented.

Thus, the Second Amendment only applies to muskets.

@Strandjunker Also - the word "own" appears nowhere in the 2A. Neither "keep" nor "bear" equals "own" in a contract - and the Constitution is the basis for our contract law.

There is not now nor has there ever been the right for any individual to own a firearm. Per the 2A, they all belong to the well regulated militia (now called the National Guard) who gets to decide who "keeps" and "bears" them until the militia says "give em back and go home".

@Alan @Strandjunker The term "well-regulated militia" seems pertinent, too. I thought the model for that would be the National guard, which keeps all the guns in an armory. 1 out, 1 in. Farmers can keep a varmint gun, and hunters and marksmen can take them out when required. Impractical in this climate though, now that the horse is already out of the barn.
