We all have our favorite chronograph. Each gives a number, but how would that number compare to the same round fired with another chronograph. I wanted to know so a friend (Rand Fishleder) and I set up the following test.
We used 3 instruments and my 6mm BRA F-class rifle with fire formed brass and 200 rounds on the new barrel.
Oehler 35P
MagnetoSpeed - V3
Lab Radar
5 rounds were fired to make sure all systems were recording and to warm the barrel.
Then the test was 20 shots fired across all three instruments with 45 seconds between shots.
The Oehler was set 7.5 yards from the muzzle so 12 fps were added to the recorded value to get back to muzzle velocity.
Results are attached.
Judge for yourself, but I was impressed by all.
