Acceptable for what? </div></div>
Acceptable for most real world conditions. In our Designated Marksman program we are required to hit a 12" target at 800 yards 3 times out of six shots. With no help from a spotter with 7.62 M118LR under any given environmental conditions.
To be able to perform the same task with a 5.56 round and at greater distance is enough to prove to me that the round is capable for most tasks that I will need it to do.
I will have to claim ignorance as to the size of an NRA target but if you are speaking of the target that is 5 feet across, the MK262 round is more than capable of hitting it and in the hands of a skilled marksman who understands how to read wind and apply corrections, you can expect hits at 1,000 yards 100% of the time.
Even if you can't call wind a 10mph full value wind will only move a MK162 round 15 inches at 1k; a 15mph wind will move the round 21 inches at the same distance. You have 30 inches from the center of the target to either side so in theory, to hit a 5 foot target you would not even need to correct for wind until the wind speed exceeds 20mph.
I train on man size and smaller targets because they are more suited to my job and what I am expected to hit.

Dude, what are you smokin'? A 10 mph full value wind will move a round as you described more like 8 feet at 1000 yards, assuming it gets there nose-on. Also, ya might want to re-think your DM program's curriculum if you think a 15 mph full value wind is only going to move point of impact 21 inches at 1000 yards, it's more like 15 MOA. That's something like 12 feet. Obviously, if you're meeting the expectations of your job, your job does not have anything to do with LR shooting. BTW, the only way your math works is if an MOA has a value of about an inch at 1000 yards. Perhaps that's where you are confused. One MOA at 1000 yards has a value of about 10.47 inches.
