I can attest to the idea that the Magnetospeed
does not effect accuracy. In my case it did effect POI. I shot 10 shots at a 5x7 gong 450 yards away and hit, or nearly hit it 9 times. With the Magnetospeed on the rifle, I had to hold lower, but hit, or nearly hit the gong 13 out of 15 times, again at 450 yards. If the Magnetospeed was going to effect accuracy in the slightest, it would have shown up at 450 yards.
