I've personally never found most of the AI cartridges to be worth it- so other than a 280 AI I don't have very much experience with them-- so this is all from what I have read and can't tell you if it is correct. But I believe that an AI chamber is actually a few thousandths shorter than a standard chamber- so that it can safely fire the standard ammo. So I think that your 223 go gauge becomes the no-go gauge. I may be wrong- but if the no go became the correct go-gauge then it wouldn't seem safe to fire form non AI ammunition in it.
