The question came up because the Wolf ammo mentioned and several other on that site are labeled as .223/5.56. Playing it safe would seem to be the prudent path, but would appreciate it if someone has specific knowledge/guidance.
I see what you mean. That is strange that they have the ammo labeled that way.
Personally, I think I would do more biz with someone who was a bit more CLEAR as to what caliber they are selling. If you had a 5.56 chamber, or a Wylde, then it would be no problem. But if you were chambered for .223, and then bought that ammo without knowing if you were going to get 5.56 or .223, then that could be an issue.
Although some feel that it isn't a problem, and it may not be, but SAAMI comes right out and tells folks NOT to fire 5.56 in their .223 chambered AR's for a reason. Whether or not they are acting like the "Surgeon General" on smoking or not, I'd rather err on the side of caution than get a face full of what used to be my upper receiver.
Or, email Ammoman for clarification of what they are actually selling.
