The amendment does not give the Attorney General - or anyone else - any new authority to ban ammunition.
The amendment does not change the definition of "armor-piercing ammunition" under federal law. Under the current federal law, 18 USC Sec. 921(a)(17)(B), ammunition is only "armor-piercing" if it has a bullet that "may be used in a handgun" and is made "entirely" from certain hard materials such as tungsten, steel, bronze or depleted uranium; or if the bullet is "designed and intended for use in a handgun" and has a jacket that weighs more than 25% of the total weight of the projectile. The current definition has been in place for more than 12 years and this amendment does not change that definition.
The amendment does not create any kind of new ammunition ban. The only ammunition that is banned as "armor-piercing ammunition" is ammunition that fits the current definition and neither the amendment nor the study would or could change the definition.
