    Unhappy Overpressure signs on Belted Mag

    Just getting into reloading

    Yesterday tried a few loads that were up to 1 grain over powder manufactures recommendations.

    The highest loads i tried had a slight deformation of the leading edge of the belt, assume this is due to overpressure? or is this something else?

    Top 3 have the deformation, bottom 1 is normal

    Wasn't sticky when extracting and nothing unusual on the heads but
    The webbing area just forward of the belt had expanded slightly more than my previous loads.
