Do longer barrels increase velocity?
Longer barrels give the propellant force more time to work on propelling the bullet. For this reason longer barrels generally provide higher velocities, everything else being equal. As the bullet moves down the bore, however, the propellant’s gas pressure behind it diminishes.
Why are 308 barrels shorter?
For a long time long barrels were used in target guns and then they started getting shorter. Short, fat barrels were more rigid and so, more accurate but when shooting at ranges long enough to take the bullet into the transonic area the added speed of the longer barrel won out.
How does length of barrel affect velocity?
Barrel length: A longer barrel extends the time time interval where chamber pressure acts on the bullet’s mass. Therefore, a longer barrel increases the exit velocity of the bullet and the effective range of the bullet. Friction limits the allowable barrel length.
