We are saying the same exact thing. The problem is you think the bullet is not stabilized when it exits the bore, and somehow stabilizes itself after a certain distance is traveled. I have no clue where that information came from and how it got to you. The 5.56 projectile is very much stabile after bore exit. The rifiling ensures that. I think you are mistaking velocity for unstabile. It is its fastest closest to the bore and the faster it is 2700 fps and faster the M193 and M855 ball rounds will fragment. The faster M193 will do it farther btw, about 200M compared to 90M for M855.
