    Most of the handgun ammo I look at shows velocity as tested from a 5" barrel.
    My Kimber has a 3" barrel and I wonder how much velocity is lost from the shorter barrel. I am pretty sure it is significant. I use Federal Hydrashok and it shows 230gr @ 900 fps. I wonder what it does from my gun?

    Is there a chart somewhere that gives 3" vs 4" vs 5" barrel length and velocity comparison?

    Thanks

    Barrel Length / Muzzle Velocity


    A little over 20 years ago the American Rifleman staff did a test using a 44 Magnum revolver equipped with a 18" barrel that was shortened in one inch increments. Five shots were fired at each barrel length, with each of the three brands of factory loads, Federal, Winchester and Remington, all using 240 gn bullets. The instrumental velocities shown are the averages obtained, after smoothing the data to remove the effects of random variations in velocity and thus to represent the incremental velocity changes more accurately.

    1" 742 FPS
    2" 935
    3" 1067
    4" 1165
    5" 1239
    6" 1298
    7" 1345
    8" 1384
    9" 1417
    10" 1445
    11" 1469
    12" 1490
    13" 1508
    14" 1525
    15" 1539
    16" 1552
    17" 1564
    18" 1575
