    Group stringing

    Looked all over for the answer including my manuals.

    When checking loads for accuracy some of them will string. Meaning there is no circular pattern. It does not mater the direction of the string, it just strings. Also the gun is being shot from a very stable rest.

    Vertical stringing is usually caused by poor breath control, horizontal stringing by poor trigger control. Not finding and correctly adjusting your natural point of aim can cause erratic stringing as well.
    No government deprives its citizens of rights without asserting that its actions are "reasonable" and "necessary" for high-sounding reasons such as "public safety."
    A right that can be regulated is no right at all, only a temporary privilege dependent upon the good will of the very government
    officials that such right is designed to constrain.

      Some loads just suck.

      Some can be tuned by altering powder charge, seating depth, and primer brand/type.

        If its stringing up and down and its not the shooter then it usually means the velocity is not consistent. This could mean the powder is not metering/weighed correctly or the weight of the bullet is inconsistent or even the cases used are not the same type and the difference is case wall thickness will cause a pressure difference between rounds.

        How large are the strings and at what distance? What are the details of your load and the rifle used?

            If it's a 22, then your gun may not like the ammo. Have you tried other ammo?

              It was the 3rd box of a different manufacture. It was the tightest group. Will try some different ammo for some latter shoots.

                Is it a rifle or a pistol? Is the barrel floated? Sometimes shimming the barrel in the forend helps with stringing.

                  It's a Ruger pistol.
