    I'm not knocking any other caliber, as there are lots of choices.
    But component cost and availibility,brass forming procedure, powder and bullet selection, magazine limitations and seating depth, case capacity, all have considerations. Some more than others.

    Both of these are variations of 6x45

    Others have far more knowledge than me, but I wanted to learn.
