Re: WEATHERBY ACCUMARK V 338/378- WHAT ACCURACY TO EXPECT ?

DUH, had a custom 338 edge built, and is killing everything on Gods green earth with it. I am positive he was glad he did not purchase a Weatherby. I have seen frustrated customers in my shop with Weatherbys that refused to shoot, and a Manf. who was not willing to make them happy. Soon they will be the GM of rifle builders. If it wasn't for the Vangaurd/Howa rifle they would already be a Government subsidie.

Did you notice this topic is 2 years old.

My personal Accumarks are all bedded now and shoot better than that. My best 3 shot group 300Wby Accumark from a hot barrel is right at 3" at 885 yards. The load is 200AB at 3100 fps. The wind just died and I had to shoot with a hot barrel. Earlier that same day none of us could even hit that target.
    After skim bedding my 3 Accumarks make a lot of these.


    What's skim bedding? And is that all you did to make it shoot that tight?

    I have a accumark in 338/378 and I average 3/4 inch to 1 inch groups with 225 grain Hornady SST with 101 to 102 grains reloader 25. I also get 5/8 to 1 inch groups with sierra 250 match kings with Retumbo, good rifle for right out of the box. I broke in the barrel and this rifle rocks!! I have the Bushnell elite 6500 in 4.5 by 30 with DOA reticle for now. The rifle has milder recoil with or without the brake than my vanguard back country in .300 win mag. Then again that was after shooting a box with my .416 Rigby with 400 grains!!

    The 338-378 accumark is as good a long range hunting rifle as you can get. All I have ever seen come through the shop would have no problem taking game at a half mile with minor work you would do with any new factory rifle. Velocity with a 26" barrel would average about 100 fps faster than a 30" 338-300 ultramag. You would also have the best platform available for a rebarrel job at some later date if you wanted. A $400 barrel from pac-nor would be awesome on the accumark.

    If you have a magnum action or can get one fairly cheap then a 338-300 ultramag barrel from pac-nor and you will have a very good long range rifle. Back in the 90's I did around seventy five 338-300 ultramags with pac-nor barrels and they all shot extremely well. Pac-nor quality is among the best. You can get a headspace guage from midway and you are in business. Screw it in, headspace and bed it the way you like and it will be a very good rifle. The plus of the 338-300 ultramag is it can get you into the low end of the big 338 chamberings with very little expense to build and then to shoot with cheap brass. No way I would ever consider paying custom money for this chambering though. Just to many better choices that beat the pants off it.

    LTLR,

    What are some of the other cartridges you prefer, albeit at a higher cost to build, load for, and shoot?

    Retumbo and 225 Accubonds have proven the most accurate so far in my 338-378 Accumark but I don't get near the FPS numbers that others here are reporting about. I get sticky bolt when I start getting much above 3275 with the 225's. I can get within 50fps of the 225's before I get a sticky bolt with the 250 Accubonds but so far the 225 out shoots them.
