There are few things you can do to the nose of a bullet that will adversely effect the accuracy. The base of the bullet is a different thing entirely. THat kind of damage to the base would be an accuracy killer.
If Georgia Arms is even remotely worth their salt, they will send you at least a box of ammo for your trouble.
In life, strive to take the high road....It offers a better field of fire.
