    Welcome aboard. Hmmmm, trying to shave <0.25" off of <1.0" @ 100 with a 338 RUM sporter! That's getting down to the fine points!

    Stock pillar & skim bedded
    Stock is a proper one for the 100yd bench shooting.
    Also, if u're shooting from a bipod, i like Froggy's advice about preloading it in the article on "bugholes From Bipods." (Kyped from sscoyote's post on another thread)
    Proper barrel break in
    Barrel is free floated except for maybe an inch or so ahead of the receiver.
    Action and bolt are mated/trued/squared(Blue printed)
    Primers seated w/a hand tool
    Scope at least 14X with parallax adjusted out.
    Fine cross hair reticle or very small dot
    There is never any wind when you shoot
    Shooting from pedestal w/ears up front and sand bag in rear.
    Shooting from very solid bench with a decent seat
    Chrono says SD and ES in single digits (not absolutely necessary @ 100 yds.
    Probably a 12" twist for the short bullet? But the twist is more than likely 1 in 10"?
    Brass is properly prep'd to the goal you have.
    Loaded rounds are straight.

    What if you looked at things just a bit differently? How about a goal of 0.75 MOA instead of 0.75" @ 100. Move your target out to 300 yds and you may already be there. The 338 RUM isn't much of a 100yd cartridge and with the 210 weight bullet it's a bit handicapped down range. 300 yds is a good distance to analyze performance with the cartridge.

    Lastly the bullet you chose may well not be the one that gets the last little bit of consistency in your rifle.

    HTH, I've just been there and done that w/a 338 RUM project. I never did get the bullet I wanted to shoot even 1 MOA at any distance but got the one I should have chosen first shooting pretty well for what I use its intended use.
    I may be the slowest guy on the mountain . . . . but . . . . I'm on the mountain!

    I would try the 225 ACCUBOND
    Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.

    first thing that came to my mind was the accubond also. i would also try cci250 primers and h1000 powder. just try different bullets.some guns just like a certain bullet over others.

    Of the 4 elk that my 338 RUM have taken, 2 were with Accubonds. It is a devastating round. My best 4 shot group with the Accubonds was 2 1/2" at 440 yds. The Swift A-Frames worked fine as well, but do not have the ideal BC you are probably looking for.

    The only complaints I had with the Accubond was that the top round in the mag had a little deformation after firing. I was hoping the polymers would not deform as badly as lead tipped bullets. The second, was that the bullet blew up on impact on an elk at about 320 yds. I don't know what happened there. The other elk taken was at about 280 and the bullet went on through.
