The parameters investigated were primarily the muzzle velocity and quality of sound produced i.e. report. The original barrel length of 28.75 inches was reduced to a final length of 16.75 inches in two inch increments. At each barrel length a digital chronograph was utilized to measure projectile velocity approximately ten feet downrange, while the sound profile was recorded via a microphone and audio software on a laptop computer. Testing took place in a single day, outdoors in a rural location in Manatee County, Florida. Weather conditions were sunny with a slight breeze, but the range was in a sheltered location between medium brush. 10 rounds of ammunition were fired for each barrel length in order to average the resultsRead More
