We tried out the new labradar today. Very slick device. It will record velocity at user selected ranges up to 100 yards. It also calculates energy and power factor.
Not suprisingly, manufacturers claimed velocities were usually 50 to 100 fps slower except for a box of cheap remington greenbox 45. We have yet to pull data off the sim card but we stored 20 different cartridges and loads. This is going to add a bew dimension to our reloading.
