I believe it was Tony of TalonTunes who explained the dynamic to me this way:

"The longer the barrel of a gun the more time the compressed air imparts its energy to the projectile", thereby providing more velocity/power to the projectile.

From AOA site promoting the 700mm barrel:

"All air rifles operate on the same principle: pressurized gas (usually air, but sometimes CO2) is introduced into the barrel behind a projectile, and the pressurized gas drives the pellet or BB down the barrel and out the muzzle."

I hope that helps.
