After all the magnetospeed will cause headaches with group tests because as you have said, it will affect barrel harmonics. I haven't watched Eric's videos in a while so could be wrong.

So the 1/3 moa groups my 223 HB shot with a magnetospeed on the muzzle were flukes?? If so then how about the 1/2 moa ones shot with a std weight Tikka?? Ive shot hundreds of groups with various magnetospeeds and never ever detected any change in group size. Like any device you attach to a rifles muzzle some rifles will show a change in point of impact . . . But thats another thing.
