He has degrees in meteorology and mining engineering, and retired from the Department of Defense after a 30 year career in Army Research, Development, Testing, and Evaluation. He taught the Arizona concealed carry course for fifteen years until the goal of Constitutional Carry was attained. It has a 3.6-inch barrel, so velocities of about 750 to 760 fps would be expected out of the shorter barrel with the 60-grain bullet.ĭean Weingarten has been a peace officer, a military officer, was on the University of Wisconsin Pistol Team for four years, and was first certified to teach firearms safety in 1973. The new Taurus Compact TX22 has a 1 in 10 twist, which should stabilize the 60-grain Aguila load. The Kel-Tec CP33 and P17 both have 1 in 14 twists, which seem to stabilize the long bullet a little better. The 60-grain bullets of the Aguila need a faster twist than 1 in 16 inches to stabilize properly. The average difference in velocity between the 5.5″ barrel and the 3.93″ barrel, looking at all five cartridges, was only 25 fps. This writer suspects it would do best out of manually operated rifles. Subjectively, it seemed to be the noisiest. ![]() ![]() With a suppressor, it was much quieter than fired without a suppressor. It appeared to contribute considerable noise from the chamber area, perhaps because of the short case. The Aguila 60-grain SniperSubSonic seemed to be the loudest. The Winchester 45 grain was a bit louder yet. The CCI Standard Velocity seemed a little louder. The next quietest was the Federal suppressor American Eagle 45 grain load. 22 pistol at temperatures lower than 40 below zero.Īs a purely subjective measurement, the quietest ammunition, using a suppressor, was the CCI Quiet. It is expected few shots will be fired from a suppressed. As relative humidity increases, there is a slight increase in the speed of sound, just a few fps. Atmospheric pressure has little effect on the speed of sound. At 70 degrees Fahrenheit, it is 1128 fps. As the temperature rises, so does the speed of sound. While the speed of sound varies with temperature, even at 40 degrees below zero, the speed of sound is above 1000 fps. As can be seen from the chart, all of the rounds tested were reliably subsonic from the pistols tested.
