I was over at the range yesterday and a friend had a chronograph set up which he showed me how to use. I was impressed as it took the velocity directly from the muzzle! Very simple to use, very easy to read and it gave velocities at the muzzle and at various yardage.
I have never done a velocity check on my hand loads so I was interested in how the number from his chronograph compared with the published load/velocity data.
I was shooting 200 gr / 35 Whelen and the estimated muzzle velocity from the loading specifications was very close to what the LabRadar unit recorded; within a couple of percentage points!
