Last weekend I learned the LabRadar will detect 357 Magnum and .454 Casull bullets on the far side of a 4'x4' cardboard target.
I had the cardboard target set 33yds from the the muzzle and the LabRadar. I had the LabRadar set to read bullet velocities @ 5, 10, 15, 20, and 25yds. After 4 shots, the Bluetooth connection was lost to my Android tablet. I turned the LabRadar off, and back on again, and regained a Bluetooth connection. I then shot another 14 times thinking the range settings were still 5, 10, 15, 20, and 25yds. After loading the bullet velocity data to my desktop computer and printing out on 11"x17" paper, I saw that the data for those last 14 shots was skewed compared to the first 4 shots.
I eventually realized the LabRadar range settings had reverted back to the settings I use when recording rifle bullet velocities, which are 15, 30, 45, 60, and 75yds. In 13 of those last 14 shots fired, the bullet velocities were recorded all the way out to 75yds. There was one bullet with bullet speed recorded to 30yds, but no farther.
The other 13 bullet velocities were recorded on the far side of my 33yd cardboard target at 45, 60, and 75yds.
Magic! Go figure. Evidently, radar function was not impeded by the thickness of my cardboard target. So you can teach an old dog new tricks after all.
