If you zeroed your rifle correctly you should be able to keep all shots in the red with a Nikon scope at 100 meters.
I don't consider my rifle zeroed until my third trip and my notes are compared.
I've logged that M855 (AE green tips) and standard 5.56 NATO rounds have not grouped very well in my MVP.
.223 rounds have been more consistent.
55 gr Vmax bullets and 62gr Barnes TSX have grouped the best.
Start with your ammo. Zero on a specific brand first. Changing ammo without taking into consideration that specific ammo's zero will cause a shift in your point of impact from your rifle.
I have cards set up for the common ammo I shoot and the zero on my P223 scope.
When I change the ammo I change the setting on my scope to accommodate it.
