    It ought to be a nice looking rifle, hope it shoots as good as it will look!
    I love those LSS stocks, I have four of them (with the bolt cutout on the correct side as opposed to yours lol.)

    OK, here's how she turned out. Put together by Jim Myers of One Hole Gunworks.

    - Remington 700 Action. Action face squared and lugs lapped into full contact. Ceracoated.
    - #4 Brux Barrel finished at 26". Beadblasted with snakeskin pattern. Name and Caliber engraved.
    - Shilen trigger, adjusted to 2.5 pounds.
    - Holland recoil lug.
    - Remington LSS Stock. Epoxy Bedded.
    - Pacific Tool and Guage Aluminum Bottom Metal.
    - Burris Extreme Bases.
    - Burris Signature Zee Rings.
    - Zeiss Conquest 4.5-14 with turrets.

    Have only done minimal load development, and only put 4 groups on paper. Largest group was 1.17" while doing the "break in" cleaning regime between each shot. (FWIW, what a pain in the butt! I now realize why I had never tried this until now, and why I won't be doing it again in the future ). Two of the four groups were in the .5 MOA range. Groups were shot at 100m:

    Winchester 7mm Mag brass with 71.5gr R22 behind 100gr Hornadys averaged 3649fps. Weatherby brass weighs about 20gr less, and gives about 85fps less with the same powder charge. 7 Mag brass formed easily into .257 Wby with one pass through a .257 full length die. Runout was horrible though (I HATE expander balls! ), with some cases having as much as .012". Even with the most crooked ammo I have ever loaded, she is showing huge promise. I look forward to seeing what she'll do when I get some straight ammo in her. I have a Forster die set coming (back order). When I get them, I'll send the sizer back to Forster to have the neck honed to .004" less than my loaded ammo measures, and won't have to use the cursed expander any more. In every instance I have tried it, it has made a HUGE difference in runout of loaded ammo and a noticeable difference in group size.

    Shot a few clays from 300 yards. From the 100m zero, it only takes 2 MOA to get on at 300 yards. The speed has to be seen to be understood. The trigger breaking and the puff of dust from the target berm seem simultaneous. Recoil is surprisingly mild. Seems on par with, or maybe a little less than my .308.

    This rig is going to Wyoming Pronghorn hunting with me in October. Can't wait!

    Have tried a few loads with 80gr and 100gr TTSXs with no success in getting them to group. 80gr TTSXs went about an inch, and 100gr TTSXs about 1.4" Not all is lost however, as my Roy seems to LOVE 110gr Accubonds, and I can certainly live with that:

    67gr Averaged 3384
    68gr Averaged 3448
    69gr Averaged 3533

    All three charges gave less than .5 MOA, and all three groups averaged .48" at 105 yards. Bolt lift with 69gr was a little sticky, so I'll probably stick with about 67.5gr. I think I'm set for October Pronghorn...

    If this is typical of Brux barrels, I'll certainly be buying more in the future!
