Impressive work. This article completely buries any other review of this nature I've ever seen.
The "Respectful discussion, a long standing tradition at AR15.com" captioned with THAT picture had my laughing out loud. I think I woke up the wife in the next room.
One question though: There appears to be an inconsistancy in the distance to 2700 fps yardage charts. In one chart, it shows that M193 out of a 20" barrel will go out to about 190-200m (~200yards), but in the ballistic chart about 11 screens below it shows that the 20" barrel M193 is only good for >2700fps up to about 150 yards. Conditions are different, but the slower chart is in less dense air, so I would have thought that the velocities would be higher, not slower.
