Does barrel length affect velocity?
For rifles with muzzle velocities in the 3001-3500 fps range, the change in velocity for each 1″ change in barrel length is 30 fps.
For rifles with muzzle velocities in the 3501-4000 fps range, the change in velocity for each 1″ change in barrel length is 40 fps..
What does a longer barrel do?
A longer barrel (in a rifle) means higher muzzle velocity, better accuracy, and a longer distance to clean. A longer barrel (in a shotgun) means less spread and higher pellet velocity. A longer barrel (in a pistol) means less space to maneuver and a bit of increased performance.
Are longer shotgun barrels more accurate?
The longer the barrel, the more precise the gun will be on longer targets and the less the perceived lead will be. On the other side, a barrel which is too long will make the gun harder to swing quickly for the close shots.
How much velocity do you lose with a shorter barrel?
As a general rule, an inch less barrel will cost a bullet between 25 and 50 fps velocity. This varies depending on powder volume and the burning rate of that powder. The more powder and the slower its burning rate, the more barrel volume needed to burn it.
Is 28 or 26 Barrel better?
26 or 28. You lose very little range and power with a 26 inch barrel. The only advantage that a longer barrel has it that is is easier to swing. You are probably losing 15 fps if that.
