[QUOTE="fiftybmg, post: 1244649, member: 96316"] Did a bit of reading, and the deviation on the target is calculated, not measured. [url=http://www.varmintal.com/aflut.htm]Varmint Al's Fluted Barrel Stiffness Analysis[/url] Exit angle variation is projected. [url=http://www.stocks-rifle.com/harmonics.htm]Rifle Accuracy: Barrel Harmonics Effects on Rifle Accuracy Explained[/url] These small calculated / projected variations should still produce sub-moa groups. A variation of 0.6 inches [ which is the max in the first link ] for a .308 means the holes overlap on the paper at 100. This doesn't explain actual group size variations by virtue of harmonics, and actually suggests that the effect of harmonics by itself is small enough to be ignored. [/QUOTE]
