Many times I hear / see people say the pellet like a certain speed. As an example they will say a certain pellet like 870fps and 910fps where it shoot accurately but not 890 fps where it is unstable and less accurate. Now, it is obvious that 890 is between the other two figures. If you shoot at 910fps, within a few meters the speed will drop to 890fps where the pellet is according to that logic unstable, but still it shoots accurate.
What I always say is that it is not that the pellet is unstable at the example of 890fps, but it is the barrel harmonics that is different in the two scenarios. A good pellet will be stable at any speed as long it is below or well below the speed of sound, depending on the pellet.
The same way we do load development with PB rifles, we do tuning with PCPs and that is to get the barrel harmonics and time of projectile exiting the barrel working together.
