    what kind of velocity drop can i expect in my 220 swift going from a 26" barrel to a 22" inch barrel?

    i originally posted this in the wrong category so i am re-posting it here
    sorry about the screw-up


    thanx for your time

    I did some looking on quickload and it looks like somewhere around 200 fps

    Hope this helps

    thanx Portx5, that is close to the loss i am getting.
    i had my swift rebuilt with a 22" lilja and my velocity dropped considerably and is still showing signs of pressure. it looks like i will be down by approximately 300 fps when its all over

    I don't have quickload, but it is on my Christmas list. Exact loss impossible to predict except over a chrono. The usual rule of thumb is about 20 - 40 fps loss per inch of barrel removal.
