Do higher velocities = better patterns?

    With so many well considered responses to PSI=Recoil and Shot Strings...this brings me to velocity.

    Does higher velocity = better patterns?

    Another thing Neil has tested.

    Generally speaking, within the bounds of typical target shell velocities, no.

    Depends on the pressure. HMB

    Sometimes it hurts and sometimes it helps. Pretty much depends on how hard the shot is and how fast you are talking about. Better? No.. As good? Yes-no and sometimes. As a blanket statement the answer is NO. Jeff

    personally, I believe the higher velocity ruins the patterns, 1200 fps makes a fine hdycp load with 1 or 1 1/8 oz.

    Higher velocities will accentuate any imperfection in your shot (pellets).

    In 2008, ten patterns were fired at 40 yards with

    Remington lights, one ounce

    Remington Nitro 27's, one ounce

    Remington lights 1 1/8 ounce

    Remington Nitro 27's, 1 1/8 ounce

    using the same well-performing Perazzi on the same day .

    The pellets were counted with Shotgun-insight software,

    The 1 1/8 ounce loads had more pellet holes everywhere than the one ounce loads.

    There was no statistically-significant difference in the patterns between the lights and the Nitro 27's of either type.

    In the above test, a difference of about 100 fps in the shells made no statistically-significant difference in the patterns they produced. There was a non-significant tendency for the faster shells to lose some density in the center and recover it in the 20-30 inch ring.

    This was a replication of a test conducted two years before with a different full-choked gun.

    In this test too, a difference of about 100 fps in the shells made no difference whatever in the patterns they produced.

    The answer is no.

    But Neil, what bearing would trigger pull have? I don't think you took that into account as a variable. Seems a trigger with an 8-lb pull would cause the shot to fly faster than one with a 3-lb pull. You know, physics and all. And postulate 6.6 and stuff.

    I always though a good example was to take a hand full of gravel and toss it slowly and see how it stays together. Throw it hard and it spreads out everywhere.Would this not be a common sense approach to this question?

    gravel thrown from your hand at 20 feet per second does not even remotely equate to lead pellets shot out of a barrel at 1200 feet per second.

    Neil, what distance did you pattern at?
    In addition to actual number of pellets in the 30" circle it would be nice to know the %. As some would suspect if you start with more pellet you should end up with more. You won't loose that many from deformation. The question is is it significant. Also 8's vs 7 1/2's. Even thou I use 1oz 7 1/2's for fitasc you don't have many pellets to start with.
    The Brits frequently use 1oz at 15-1600fps with good results. They also measure speed at the muzzle.
