The only time I've had it miss during a normal shoot is with a small bullet going fast…small and fast like a .17 hornet.
The only other misses were shooter induced error. I've moved the unit with muzzle blast…that caused an error. I've shot it on the mount, with a few misses but garmin came out and said it wasn't recoil rated. So that's that.
I've shot it on unstable platforms, where the recoil as moved the structure supporting the gun and the garmin, which has also made a few misses.
But never just regular shooting regular bullets in a usual manner. It's been real fine like.
