I wonder if the shorter rotational axis allows the pellet to change direction easier than a longer pellet? With bullet lengths and barrel twist rates having a close relationship in the centre fire world it makes you wonder how much the rotational stability created by the twist rate influences pellets? There will certainly be a best twist rate and velocity for any pellet type when it comes to bucking the wind, projectile length is one of the important governing factors when choosing ammo for a given twist rate in centre fire rifles.
HFT, for people with only 2 buttucks!
