    I push those 200 gr. WFN's to 1,250 fps.
    When I used to shoot USPSA/IDPA matches, we would go by "power factor". PF is bullet weight in grains times velocity in feet per second.

    It usually gives a number in the 100 or 200 thousands.

    You drop the three digits on the right and just keep or use the 3 digits on the left.

    In your case, the PF is 250.

    As a comparison, Winchester White Box .45ACP is a 196 power factor out of my 5" 1911s.

    So you all's 10mm loads pack quite the wallup.

    They should be good med'cin for bowling pins.

    I went with a 40-200G from Accurate. I think it is very sim to the 40-200F.

    The 40-200F is close to your "G", but quite a bit narrower in the meplat. Yours is pretty nice boolit!

    Here are the "F"s.
