Mule Deer - how hard is it to maintain alignment between the bullet path and the Magentospeed from shot to shot, and from rifle to rifle? And, if there is misalignment, does it reduce measurement accuracy, or, does the unit completely stop working so you know you have a problem before collecting a bunch of bad data?
I have found it easy to "maintain alignment" with the setup. I adjust the rest, and my forend rest, so the muzzle of the rifle hovers just above the V-block at the rear of the MagnetoSpeed when shooting.
It's just about impossible to get a "bad" reading with the MS. Either there's a reading or there isn't. The only times it's missed a reading is when I screwed up and the rifle's muzzle was a little too high above the V-block--which can occur if one rifle has a thicker forend than the others I'm testing, and I forget to adjust the forend rest to compensate.
