Should civilians have access to M855 ammo?

So given owning guns and joining the military have a relatively strong correlation of populations, I imagine a good chunk of you have heard about the ATF moving to ban M855 ammo, that same lovely green tip that we're all at least annually familiar with. The ATF is arguing that what makes up a good chunk of the surplus ammo market is magically now armor piercing ammunition because of the steel penetrator (which does not qualify the M855 for armor piercing status per Federal law) and because, like all rifle ammunition including .22 Mag, it can pierce a NIJ IIA vest (Rated to defeat low speed 9x19mm ammo and 40S&W). So from a legal and physics perspective this is rather out of whack, and the law under which the ATF is claiming authority to do this specifically omits centerfire rifle rounds, specifically because every rifle round made can defeat the vest used for the standard.

If you want more information, I've done some extensive writing with my coworkers here: https://www.facebook.com/notes/ [login to see] 03343/

So it comes down to this. Should civilians be able to purchase/own the M855/SS109 ball round?
