Response to What does an airstripper do on an airgun? YIA
Some people believe that the gas that is pushing the pellet out of the barrel of the airgun creates turbulence at the muzzle when the gas escapes. The airstripper is supposed to direct that gas away from the path of the pellet so that any turbulence that is created does not affect the pellet.
For a pneumatic gun or a CO2 gun, this argument might have some merit.
Ideally, the pellet's skirt would trap all of the gas behind the pellet such that the propelling gas is not released from the muzzle until the pellet has already left the barrel. Then, the pellet should be traveling at such a velocity that the pellet is long gone by the time the gas creates enough turbulence to affect the pellet's trajectory. However, in actual practice, there is probably some gas blow by around the pellet as the pellet is propelled down the barrel and there probably is some gas exiting the muzzle ahead of the pellet.
As an aside, there is a video on YouTube of someone rat catching with an airgun at night using some kind of IR scope and IR video camera. The video camera angle looks like the camera is right in line with the scope. In the videos, you can actually see the air being expelled from the gun and making what looks like a very wide tracer image extending about 1/2 of the way to the target. As the camera uses an IR emitter, the camera is picking up reflected IR from the turbulent air stream and the tracer looks white or lightly colored.
How much turbulence is needed to affect the pellet is debatable. In one sense, any turbulence must be bad as it causes a non-reproducible effect on the trajectory of the pellet, therefore getting rid of all turbulence would be desirable. However, there are a lot of other variables that are far more important to deal with than turbulence when trying to get the most precision out of an airgun. The quality of the barrel, how much it is worn, the quality of the crowning, the quality of the pellet and the consistency of the pneumatic charge are all going to have a greater effect on precision than turbulence at the barrel.
All that being said, some of the airstrippers are absolutely gorgeous pieces of machining and really add some bling to an airgun.
