ActivShootr,

Optimum barrel length depends on the powder burn rate, the volume of the powder charge and the payload weight. As long as the pressure in the bore remains higher than the resistance of the payload, the velocity will continue to increase until the load clears the muzzle. The longer the barrel you have to work with, the more versatility it will provide in load building.

If a barrel length of 26" was optimum, why then do most all ammunition companies use test barrels that are 30"+ in length to obtain their load data? Scroll up and read my previous post under this thread.
