Not only common but acceptable and even good. As per FM3-22.9 5.1 the minimum standard for zeroing is six rounds into a 4cm circle at 25 meters. That works out to slightly greater than 6 MOA at 100 yards.

I am glad someone actually quoted the military standard for ball ammo performance.

The AR-15 has gotten a reputation as a rifle that is more accurate that most autoloaders (2-3MOA), and we have become spoiled by that.

The fact is the military spec. will allow a combination of ammo and rifle to be MUCH greater than the average shooter sees.

When guys have a rifle built using pseudo-military spec. parts and feed it bulk ammo, and get 4 or 5 MOA, they tend to assume the rifle is junk, but in reality, it's meeting the military expectations.

I hope to get some good testing done on this weekend with the 62gr Winchester.

Here is a chart I use when researching ARs.
