In Bryan Litz’ e-book “Precision and Precision for Lengthy Variety Capturing” he states that two with the precision aspects are the short range precision of the weapon method along with the SD in the muzzle velocity. Basically, he employs the words rifle precision in certain destinations, rifle-ammo precision in a few and rifle-ammo-shooter in Other individuals.
