This is Caylen Wojcik, Precision Rifle Instructor for Magpul Dynamics with a MagnetoSpeed chronometer mounted to a PROOF Research TACII in .300WM.
PROOF Research uses a patented manufacturing processes using carbon-fiber wrapped barrels to offer the disciplined shooter proven accuracy, longevity and durability. It’s pretty cool. I fired a couple of their weapons at SHOT Show 2013.
If you’ve ever used a chrono, then you know what a pain they can be. That’s why I’m so stoked about the MagnetoSpeed because its barrel mounted, right to the gun. Rather than using screens, it relies on magnetic sensors. Check it out.
