Is ammo bans or restrictions a backdoor attack on the right to bear arms?

Is regulating or banning bullets a backdoor way of attacking the right to bear arms? Since those who don’t want guns or people to have them can’t stop them because the NRA does a good job protecting the right to bear arms those cities plague with crime or gang violence use that as a reason to ban certain ammo, restrict ammo gun shop/dealers can sell and require I.D. and finger prints to buy ammo? Since weapons committed in crimes tend to travel great distances or come from outside the communities they are used in will restricting ammo for legit gun owners really slow crime down in those high crime areas?
