My rifle was initially zeroed with the 55 grain, and when I loaded up the other stuff, it consistently impacted about 4 inches higher before I re-sighted. Have gotten pretty much identical results each time I've switched back and forth between the two.

4 inches of difference at what range?

With both 25 and 100 yard zeros.

Why would anybody wanna shoot 5.56 anyway, provided they have a choice?

The sight post and rear aperture could be loose, or the irons are loosely mounted on the rifle? I will check both.

I don't think this 62 gr ammo could be considered a close M855 clone, so perhaps that explains the difference. Shorter bullet, and MV is 200-300 fps slower. I apologize if my initial post regarding POI of this particular brand may have been misleading if considering the qualities of mil-grade ammo.
