No disagreement to what you and mehavey are saying--his illustration shows the problem perfectly. What I am pointing out--is that you could have ammo or component manufacturers staying within specs and still have a potential for problem. I mentioned to mehavey earlier the issue of the depth of the radius chamfer cut to the chamber face as being a contributor to the problem. Again, I believe that if the AR set-up I have complied with ptg's default for 1.714 on the no-go (I'm guessing ptg also makes the chamber and bore reamers many manufacturers are using) most likely there would be no issues even with the AR I have.
If you’re ever hiking in the woods and you get lost, just look up and find the brightest star in the sky and you’ll know which way space is.
I am NOT an expert--I do not have any formal experience or certification in firearms use or testing; use any information I post at your own risk!
