Spark photography range tests were conducted in the BRL Aerodynamics Range, for caliber .22 Long Rifle match ammunition fired from Olympic-grade competition rifles. The spark range measurements were used to accurately quantify the effect of wind on the trajectory of caliber .22 match ammunition. The tests included two commercial brands of match ammunition and two Olympic- grade rifles. No significant difference in aeroballistic characteristics due to either rifle or ammunition brand could be found.
