For the MOA junkies...............

Postby hammAR on Tue Feb 08, 2011 10:31 am

Just thought that I would post this as a kind of reference point for all to consider when they discuss their 5 shot groups at 50 or 100 yds.................

Doing MOA capability testing is expensive. This is done by shooting 100 shots, no less than 2 minutes between each shot, correcting for conditions on each shot at 90% of the gun's supersonic range. You count the number of shots within an x MOA diameter. 80% of those shots in an x MOA arc within 90% of supersonic capability gives a REAL MOA value capability for a military grade long range rifle. If 80% of those shots fall within 0.9 MOA, then that is the gun's capability. If humans are shooting the guns, then you should use at least 5 shooters and average the values. Of course, a gun's individual capability should be tested at 200 yards (180 m) to determine if the gun can hold a real group or not. We did this with the .408 in 2001 and 2002. Gives honest numbers, but costs a lot. (statement by Mr. Dean Michaelis, former co-owner and test shooter of CheyTac LLC)

Accuracy -

Groups of 7–9 inches (18–23 cm) at 1,000 yards (914 m), 10 inches (25 cm) at 1500 yards (1372 m) and 15 inches (38) cm at 2,000 yards (1,829 m) have been consistently obtained and varified.

Groups of 19 inches (48 cm) at 2,100 yards (1,920 m) and 29 inches (74 cm) at 2,400 yards (2,195 m) have also been obtained.

All groups that are up to 3,000 yards (2,743 m) are less than 1 minute of angle for vertical dispersion.

Records -

The world record for best group at a distance, landing 3 bullets within 16⅝ inches (42 cm) at 2,321 yards (2,122 m) near Arco in Idaho.

Was that world record best group done with the CheyTac M200?
