.22 Mag Results in fps
An additional note on the .22 Mag (officially, the .22 Winchester Magnum Rimfire) data: this sequence of tests presented a real challenge for our chronographs, probably because the .22 Mag is one of the smaller bullets commercially used yet is driven at high speed. Modern chronograph technology is based on optical sensors used to determine the period of time a bullet takes to pass between two sensors. The smaller the bullet, the harder it is for the optical sensor to detect it, and the more necessary it is to get the bullet exactly over the sensor's field of vision. For most of the test we were confident that our results were accurate, and if you look at the raw data sheets you will see that we were able to usually get four or five 'good' readings (out of six possible - three shots each over a pair of aligned chronographs). However, towards the end of the tests (when the barrel was starting to get very short) accuracy became an increasingly difficult proposition. At that point we switched to a more expensive Oehler brand chrono system, which uses twin chronographs to automatically calculate one reading. For the last measurements in the chop tests - when the barrel was only 2" - we were only able to obtain one or two readings for each type of ammo. The readings were consistent with the curves we had seen through the rest of the testing, but doesn't have the same degree of supporting data.
