    I need someone who has quickload to help me out if you would I'd greatly appreciate it. I have new nosler brass I need info for my remington 300 ultra mag sendero I plan on loading 101.1 grains of us 869 powder with federal 215 match primers OAL will be 3.675 . ,210 grain berger, barrel 1-10 twist 26'' long.

    Thanks BIGBUCK:)

    This output data is only as good as the input data. To give a more accurate results your exact case capacity and chronograph readings from several different loads would be needed, but what you gave should be enough to get you in the ball park. Though this simulation may be very accurate you still need to work up carefully.






    Will repost the corrected data!

    Thank you steve for your help, I have 6 rounds loaded already with 101.1 grains of us 869 I kind of wish that I would of taken a look at these numbers befor I started.

    Thanks ,

    This should be a bit more realistic, but like I said before, it is best to work up the load over a chronograph. Special attention should be given to the two variations of powder burn rate. Increasing the burn rate by 10% takes a nominal 54kpsi load to a 65+kpsi without a change it charge weight, so as usual work up the load slowly. By that I mean start low (say 96-97gr), if a chronograph is used, a step of 1gr intervals is not out of the question with a case capacity that of the RUM.


    The columns read
    1st % of 101.1gr
    2nd % of case filled
    3rd Actual charge weight in grains
    4th Velocity in fps
    5th Energy in lb*ft
    6th Pressure maximum in psi
    7th Muzzel pressure in psi
    8th % of propellent burned
    9th Propellent burn time in milli seconds

    Cartridge : .300 Rem Ultra Mag
    Bullet : .308, 210, Berger M T VLD
    Useable Case Capaci: 101.203 grain H2O = 6.571 cm³
    Cartridge O.A.L. L6: 3.675 inch = 93.35 mm
    Barrel Length : 26.0 inch = 660.4 mm
    Powder : Hodgdon US 869

    Predicted data by increasing and decreasing the given charge,
    incremented in steps of 2.0% of nominal charge.
    CAUTION: Figures exceed maximum and minimum recommended loads !
