Quoted:
i would venture to say that the twist of the bore would correct this as the bullet traveled down the barrel, but barrel life could be affected somewhat.

So close, yet so far away,
The accuracy of a bullet in regards to the bore is that the bullet needs to cleanly imbed into the rifling, and glide down the bore/rifling in complete contact for a consistent spin/engagement. Items like a long jump to lands (read bullet traveling without rotation then hitting the lands), or the projectile not parallel with the bore during engagement causes less than stellar consistent engagement/ unified travel down the bore, which leads to deviations of shot strings (back to barrel harmonics and the exit point of the bullets out the muzzle during barrel whip), hence variations of accuracy regarding shot string groups.
P.S. Not trying to bust you balls, you just have to remember that at one time I chased the Holy Grail in bench shooting (read groups less than .1 MOA). In regards to the AR service rifle, my thoughts could be way over the top, but if the rifle is taken to the edge (read match type shooting), then these concepts become more valid.
