[QUOTE="MNbogboy, post: 1552911, member: 18849"] I use both the Magneto speed and an optical. To me both have advantages and disadvantages as mentioned through out this thread. I have a permanent "chrony" box mount 15 feet from my bench. 100 yard target perfect alignment with bench, Chrony and target. 10 seconds set-up time. Everything at 100 yards through the chrony. My magneto speed sporter is used only a few shots at beginning of each session to "calibrate" the chrony. Adjustments are made to Chrony readings accordingly for the rest of the session. Obviously light conditions must be consistent for using the "adjusted" readings. My magneto speed does affect my POI on the sporter barrels I shoot. It seems to always shoot high. The magneto speed always stays in place with the extra rubber spacer on top of the barrel under the strap. The magneto speed is super consistent as far as repeatability. SDs seem to be lower because of this consistency. Chrony is only accurate plus or minus 1%-2% (30-60 fps @ 3000fps). Light conditions must remain constant for repeatable results. I will continue to use both but the magneto speed still comes off after the first 5-10 shots with each load in a range session. Magneto speed back on to verify final velocities. [/QUOTE]
