    Any of you guys have any loads you can share for your 338 RUM using H1000? I am interested in 200 gr and 225 gr AB loads.
    I have had great luck with both RL22 and RL25 getting .5 MOA, I am just wanting to try the Hodgdon Extream powder.
    Thanks for any info you can share.

    Regards,

    I tried H1000 in my 700 LSS 338 RUM with the 200 gr Nosler AB. 101.0 grs R-P case and Federal GM215M primer gave me a 3 shot group of .599" at 100 yds.

    Not ABs but Hornaday 225s:
    92gr H-1000 average vel 2960 FPS - Shot patterns not groups.

    94gr 7828, 3 Shot Average 3099 FPS average PSI ~63000 1/2 MOA. One group only. I'll try to duplicate it if I can't get any 250s shooting.

    250gr Nosler partition, 94.5gr RL-25, 3 shot avg. 2990, 1 MOA.
    250 NOS Part. 101gr Retumbo, 3068 FPS (3 shots) - pattern vs group.

    Here's something to think about:
    All loads: Sierra 250gr Game Kings, 94.5gr RL25, 3 shot averages.
    Seating depth, Base to Ogive: 3.240, Avg FPS 3006 ES 41
    Seating depth, Base to Ogive: 3.072, Avg FPS 2947 ES 26
    Seating depth, Base to Ogive: 3.016, Avg FPS 2915 ES 23
    Target shows a pattern vs group on these 9 shots.

    BTW thanks for the load data from a while back.

    I'm having to seat all bullets fairly deep to get anything that could be considered accurate, but then not very addurate, so far. /ubbthreads/images/graemlins/crazy.gif

    I must have the slowest most inaccurate 338 RUM in the world. My best group came from the last 5 shots of the Final Finish process???

    Roy,

    The best accuracy, by far, has been RL22 and RL25 in my 338 RUM. The same load data I sent you a while back.
    I just put some M1 dials on a VXIII 2.5x8 and did some shooting with the 200 gr AB.
    100 yd zero
    200 yd 1+1 MOA 2 shot group measured .262"!
    300 yd 2+0 MOA 3 shot group measured 1.987"
    400 yd 4+0 MOA 3 shot group measured 2.265", 2 shots were .507"!

    My come ups were less than what my ballistic program called out. I have tried changing the velocity and the BC trying to match up with my actual reading but with no luck.
    I will have a chronograph soon to eleminate the MV guessing game.

    Now I'm depressed. I think I'll sit in the closet and eat worms. /ubbthreads/images/graemlins/grin.gif /ubbthreads/images/graemlins/grin.gif

    We'll see what today or tomorrow says.....

    Here is a picture of my 700LSS in 338 RUM.
    Stock rifle with a Pachmyer Decelerator reciol pad and the trigger adjusted to 2.75 lbs.
    Scope is a Leupold VXIII 2.5x8 with M1 dials.
    I am planning on a Mark 4 4.5x14PR and having M1 dials added next year.

    Here is my Rem 700 APR 338 Ultra mag. It does well with 90 grains of H-1000 but really shines with 96 grains of RL 95 and the 225 Accubond. It has the Mark4 405-14 PR scope mounted. 300 yard groups average 1.5 inches. In the hands of someone that can shoot it would do much better. I also have one of these in 300 Ultra.

    Very nice Roy!
    If I can ever get some more 225 gr AB's from Shooters Pro Shop, I will work on breaking the .5" using the same load, 96.0 grs of RL25. My best group to date with that load is .587". COL is 3.360".

    You and me both, JD!
    I got higher velocity out of my 26" bbl 700 with 7828 than H1000 with the 225AB. I was running into compressed load problems (not really problems, just a little crunching when seating) with H1000 and Retumbo.
    I understand why you want to try the Extreme powder. I think that 7828 and RL22 are optimal burning rate for this weight range--200 to 225 gr. 7828 fills the case nicely if you are seating to function through the 700 magazine. What I don't know yet is how stable these powders are in differing temp ranges, hence the advantage of the Hogdon Extreme stuff.
    Good looking rig by the way. I have 3 LSS's myself (left handed, of course!)

    Good luck and keep us posted. We want elk kill pics!

    Sam,

    Here is my 5 pt Bull from CO in 2002.
    Used my 700 LSS in 338 RUM with a 210 gr PT. Range was 350 yds, dropped him in his tracks.

    Suhweet!
    I'm going to hunt unit 62 armed with my first bull tag this year. I've killed 2 cows so far. My buddy had to watch 2 legal bulls last year, a 5x5 and a nice 6x6--no bull tag. He did kill a nice big cow, his first elk.

    Hope you shoot a big'un this year!

    JD338,

    Hope you were close to the road. Looks like a fun pack out /ubbthreads/images/graemlins/crazy.gif

    210 PT, eh? Sounds like a great load.

    I'll be tuning on mine starting day after tomorrow. Temps are supposed to be down in the mid 70s. That's gonna be nice for a change.

    Road? What Road?
    Sweetwater Lake, CO 9800'
    Pack train, and one heck of a ride out! I think I was breathing harder than the horses. I was about 200' above 3 legal bulls. Shot the biggest one of the bunch when everything lined up in the aspens. The 210 gr PT put him roght down. Exit wound was the size of a golf ball.

    That's what I call Livin' Large.

    Exciting hunt. Hell I'm pretty sure I'd have got the fever some time when things were getting lined out and blew the whole deal. /ubbthreads/images/graemlins/crazy.gif

    I was yote huntin' out back of the house and watched a nice shooter 5X5 for 20 minutes @ 395 and couldn't shoot as my tag was for the adjacent unit. /ubbthreads/images/graemlins/mad.gif

    To rub salt in the wound, I went to get the newspaper one morning after a snow and after the season and elk had been bedded under the pine tree in my front yard. A laser measured 15 yards from the freezer. /ubbthreads/images/graemlins/crazy.gif /ubbthreads/images/graemlins/mad.gif
