Muzzle velocity between barrels.

Hypothetical
Two barrels, same length, same load. What would be an expected variation in speed? Think two factory rifles with factory ammo.

Could be the same to 200fps different. I had a 26" Mike Rock an a 22" Pac-Nor that ran the same speed with the same load. I've had 2 300wm PSS's that were 125fps apart with the same load. Speed is not the be all, placement is.
