    Anyone got any load data for 25/35 using IMR 4198?

    Ok I have a buddy who is casting for his 99 Savage in 25/35 , using a 120 gr gc RCBS mold. He has a huge amount of IMR 4198, so anyone have any data for this bullet and this powder, all feedback appreciated.

    I've used 14-15 grains of 4198 in my Marlin when I was playing with it. 25-100-FN RCBS bullet weighing around 110 grains. Gave me about 1800 FPS. Place to start./beagle

    Not load data, but the following Quickload table may be helpful:

    Code:
    Cartridge          : .25-35 Win.
    Bullet             : .257, 117, RCBS SP GC 257-120-SP
    Useable Case Capaci: 30.319 grain H2O = 1.969 cm³
    Cartridge O.A.L. L6: 2.550 inch = 64.77 mm
    Barrel Length      : 22.0 inch = 558.8 mm
    Powder             : IMR 4198
    
    Predicted data by increasing and decreasing the given charge,
    incremented in steps of 1.0% of nominal charge.
    CAUTION: Figures exceed maximum and minimum recommended loads !

    Powder             : IMR 4198
    
    Predicted data by increasing and decreasing the given charge,

    According to Hodgdon, 18.8/H4198/117 gr. Hdy. RN gives 36,100 p.s.i. and 2065 f/s from a 24" barrel.
    The higher velocity from the quick load program makes sense, in terms of their projectile having a higher lubricity, even with a gas check. QL suggests that you have some room to improve over Hodgdon's results. If your firearm is not of post-war vintage, I'd stay conservative.
    For in much wisdom is much grief: and he that increaseth knowledge increaseth sorrow. Ecclesiastes 1:18
    He that troubleth his own house shall inherit the wind: and the fool become servant to the wise of heart. Proverbs 11:29
    ...Verily I say unto you, Inasmuch as ye have done it unto one of the least of my brethren, ye have done it unto me. Matthew 25:40
