How accurate have your Magneto-Speed velocities been? A buddy of mine who is one of the best Palma shooters in the country says they are very accurate. I've had decent luck using them but used one with a suppressor this week and had an issue. The chrono said I was at 2608fps with an SD of 10fps. When I trued my drops at 800m with a known BC bullet (accurate within 1% per Applied Ballistics ) my ballistic solver said my velocity was 2671fps given my actual drops.
