[QUOTE="Bart B, post: 1156907, member: 5302"] SAAMI's tests say centerfire barrels increase velocity as length grows. They used fixed barreled actions eliminating the human caused velocity errors. A 100 fps spread in average muzzle velocity across several people shooting the same rifle and ammo happens. I've no idea how those tests referenced were conducted; if hand held, I'll have to see the actual numbers to pass judgement on them. Some rimfire barrels do loose velocity as their lengths grow to bigger numbers. [/QUOTE]
