    It appears to me that the higher velocity ammo is affected more by the shorter barrel

    These are the velocities after a further one inch was cut off.[/quote]

    I missed the start of this discussion. What barrel length did you start with and what is the increase per inch.
    My experience is also that higher velocity cartridges are more effected. I just cut 4in off a Savage B22F (21in to 17in) but haven't had a chance to chrono yet. Will post results when I do.
