Not really, the 2 groups (top group 4 shots, bottom group 2 shots) were shot with the MagnetoSpeed attached. Generally accepted that the bullet will move away from the sensor and is in most cases the sensor is at 6 o'clock the elevation will be affected. The sensor would be just as happy mounted 3 or 9 o'clock and 12 for that matter (shooter may not be happy).

May affect thinner barrels perhaps. The thinnest I have used it on was my CZ Varmint 223 and accuracy was vg and no different to the groups I get without the sensor mounted.

I have found some scorching on the sensor arm but not on the sensors themselves. The scorching is cosmetic only and no biggie unless you get anal about such things.
