    I was wondering if someone with Quick Load could look up a predicted velocity for me. I'm having a 338 norma built and would like to know the expected velocity. I know it will vary from real world data, and I do have a chrony. Just want to see ball park velocity data to decide if I need to go longer on my barrel before it's cut.
    Don't know all the inputs needed, but
    Barrel 1-9.5 25"
    retumbo 90 grains
    106 grn h20 capacity
    300 smk and 300 berger @ 3.6"
    3,800' ASL
    Thank You!

    Thank you so much! It really burns full in 14.2" of barrel or is that a typo? 24.2" sounds more reasonable.

    Just went and checked it and Quick Load has it 100% burned at 14.2189".

    Just ran a quick compairson only changing the powder and used IMR 7828. 99.99% burn as the bullet exits the barrel with a vel of 2611fps and the fill is 98.5%

    Hope this helps.

    Jim,
    If it's not too much trouble from you could you run 26" and 27" barrel for me?
    Thanks.
