Colonel:
Bottom line is that you could not use it in a match, as it would be altered ammo. So why do it, if you can't use it.?? Now if your just playing around and not shooting matches, you can do anything you like to your ammo.. I know one person who cut an "X" in the nose of his bullets and claimed that it shot much better in the wind than the regular nose.. Try anything you want to, it's your ammo..
