    That has to do with cartridge overall length, but sort of, yes. It's a risk, but not a high one. AR chamberings tend to be 5.56mm, the longer one, and bolt action rifle chamberings tend to be in .223, which is the shorter of the two. Most people with .223 bolt actions purchase .223, as that's what's engraved on the barrel, and most people AR's purchase whatever's cheapest, so it really doesn't matter.
    I knew they had different pressures but I didn't know one was longer. Good to know.

      Right, but it's a pretty low risk, given people's purchase patterns.

        The cases are identical.

          What would the signs be of over pressure? I still have most of the brass casings that I have shot out of it. It was a few hundred rounds of Winchester white box and a couple thousand rounds of cheap steel case stuff of various brands.

            flattened primers, or even bulging primers.

              Right, I meant OAL.

                Yes, even then the bullet's ogive can change the leade leaving the COL the same. Here's a really good picture to show what exactly the leade is, as it's pretty confusing to some of the other guys I'm sure.

                  The Sierra manual only goes up to 150gr bullets in 308 diameter and 125gr in 311 diameter stuff.
