I was able to do this this morning. I had the MagnetoSpeed on the muzzle while shooting through the sky screen window of the Oehler. Sky conditions were perfect for the Oehler- nicely overcast. Below are the individual shot readings, in the order fired. Velocities for the Oehler are instrumental readings, so muzzle velocities would be about 10 fps higher. MagnetoSpeed readings are the top line of each. The average difference between the instruments for all shots is in the low teens with differences decreasing as bullet diameter increased. I'm impressed!
