Directly from the MagnetoSpeed website. I assume they've tested.
Can the MagnetoSpeed affect barrel harmonics (e.g. the location and size of my shot grouping)?

Yes, with most guns you will be able to see a shift in your point of impact. Some people say it has no affect on their guns so it seems to be a case by case basis. Group sizes seem to be relatively unaffected though by the MagnetoSpeed.
