Fucking seriously? I checked the ATF website and it wasn't a joke, 5.56 and .30-06 are the only two calibers they say are legal to have with a steel core. CTD however sells .50 BMG AP rounds all damn day along with 5.56 M855 and .30-06 M2 AP but they couldn't sell 7.62 NATO with a steel core because it's banned specifically? I'm wondering why they think you can get a handgun in .308 but not .223 or .30-06. I double checked because I thought the guy was full of shit but I'm sorry to say he's right.
