It depends. I do not think anyone sells the 855 that is issued because of the tungsten tip. So, the stuff you are getting is probably pure lead core which should give more consistent performance than the issued stuff.
I am convinced that the little tungsten tip in the issued 855, if not very well aligned with the core, causes the problems with that particular round of ammo. Issued barrels, trashed from incessant blasting while conducting SRM, don't help the situation either.
That said, just about any commercially made AR will probably shoot better than its issued counterpart. I mention this because if you do run any tests, your rifle and ammo are probably not representative of the issued side.
My experience with issued M-4's and issued 855 using what ever low power optic Joe has is that given no wind conditions, ideal lighting, ideal contrast between target and background, that this combination is about maxed out at 500 yards on a upper torso size target. Past that and things become more chance than deliberate.
