Thrown stones are a fast firing deadly weapon. They, compressed air guns, and ball musket etc aren’t used by modern military forces in combat because they are less dangerous.
A rule that allows compressed air weapons yet bans percussion caps is quite reasonable and could pass constitutional scrutiny.
It might be quite reasonable, but it would also quite clearly require an amendment to do in the US, which is what you originally replied to.
