I'm surprised no one has mentioned this, but a 3-shot group that measures 0.75" at 100 yards doesn't necessarily equal a .75 MOA rifle.
You can shoot successive 3-shot groups and one might be 0.75" and the next may be 1.5" with zero effects from the wind, parallax, or whatever, just inherent variability.
In other words, don't read too much into a comparison of two three-shot groups.
Thats a given, but good point. Some may not know that here? One reason I shoot 10 shot groups. When I talk about a sub moa or moa rifle, its a rifle that averages that with 10 shot groups. You also have a better idea of where that rifles true zero is as well. As has been discussed, in other threads, 3 shot groups are damn near worthless when wanting to know the rifles true capability.
