High Quality Content by WIKIPEDIA articles! The Voere VEC-91, made by Voere, is the first commercial sporting rifle to combine caseless ammunition and electronic firing. Depending upon its chambering, it fires a 5.7 mm or 6 mm projectile at speeds of up to 930 meters per second (3,051 feet per second). When chambered for 5.7 mm it has a 5 round magazine, and it has a 4 round magazine when chambered in 6 mm. Two 15 volt batteries, located in the pistol grip, allow it to fire approximately 5,000 rounds without replacing the batteries.
