I know that there have been several requests lately for Chronograph accuracy and repeatability information - so here are the results from my latest field test.
The CED M2 was placed 12 feet from the muzzle and the Oehler 35P was placed directly behind the CED (within an inch) Time of day was 2PM. Velocity was 2850. 10 rounds were fired from a favorite 6.5 X 47L load that had a known velocity and an extremely low SD and ES.
After half of the shots had been clocked we began to laugh at how close the results were. The end result was that the CED M2 clocked 9 of the 10 rounds at exactly 7 fps faster than the 35P and 1 round 6 fps faster. " Keep in mind that the CED's front screen was roughly 2 feet in front of the 35P - so velocities would be a hair faster. I found this test to be unbelievably favorable to both units.
