I read today on 300 blk forum that the ATF has decided that for now m855 is still considered a sporting round and not armor piercing. I personally think they weren't prepared for the blowback they got from the public as well as the politians and there just regouping. There going to review and publish all 80,000 comments and revisit this at another time. So good news no more 223 ammo scare hope you didn't rush out and buy a bunch in the past week or so and if you did maybe you can sell it quick and buy it for half the price later.
