    en.wikipedia.org/wiki/9×23mm_Winchester

    The critical design feature of the 9×23mm Winchester is a much-strengthened case that does away with the semi-rimmed case design of the .38 Super which sometimes caused feeding problems.

    Competitors in the late 1980s and early 1990s who were using the 9×25mm Dillon used the additional powder available over .38 Super to produce more gas in the compensator, or muzzle brake, to make pistols shoot with as little muzzle rise as possible to allow faster follow-up shots on target.

    en.wikipedia.org/wiki/Power_factor_(shooting_sports)

    The desire to get the benefit of major scoring has led to some competitors adopting high speed 9 mm cartridges loaded to major, such as .38 Super.

The .38 Super caliber became popular ...
