    This is my first post, so be kind if it takes me a couple trys to get it right.

    I did a little work with surplus powders lately in a 30-338 lapua and thought some of you would be interested in what I found.

    My rifle has a 30" one in ten twist Lilja Barrel chambered in the standard 30-338 lapua, the case holds 116 gr. of water with the overflow method.

    I have included H50BMG for comparison.I have shot this powder the most in this rifle. I used Sierra bullets for all load work listed here.

    Powder H50BMG
    Bullet Max load Vel
    220 BTHP-M 100gr 3171
    240 BTHP-M 95gr 2951

    Powder IMR5010 LOT# LC 12699HP
    Bullet Max Load Vel
    220 HPBT-M 97gr 3154

    Bullet Max Load Vel
    220 BTHP-M 102gr 3057

    stmag1,
    Thanks for the info. I have a 30/338 Lapua Imp. of my own design that I call the 300 WAMBOMAG. I also have tried WC872 and with a 33.25" barrel and 105grs I've pushed the 240 SMK to 3100fps with pretty good accuracy. The best accuracy is around 2950-3000fps using 100grs.
    Take care,
    Wayne

    stmag1, very useful info. I shoot a 300RUM and get 3075fps using H50BMG and 240gr MK out of a 33" barrel.

    I am surprised about the WC872 vel. I would have expected it to be higher. What criteria did you use to determine the max load?

    I just used the primers as a pressure sign mostly. The first day I recieved the powders I set the gun up outside the shop without the cronagraph and just worked up to what I consider desent pressure. The next day I shot the top loads for velocity. In all honesty I'm probably a litte more conservative than most.
    I dont like killing brass for 25 fps if I can avoid it. But you know how that goes, seems like half the rifles I have dont start to shine until their right at the top.Still I try to find a load off the top a tad if I can.
