Boomer XP build finished in the shop......
One of our member here contacted me a while back wanting and unique cartridge to run in an XP. Something larger and in the .338 family for elk, hogs and exotics. After discussing our options, I suggested the .338 Ruger Compact Magnum. Being designed to run against the .338 Win Mag, but in a shorter barrel, I figured she'd be an ideal thumper in an XP platform.

We started by going thru the action, squared everything up, added a PTG bolt release and fitted a new bolt from PTG. The bolt was their spiral fluted bolt, mag boltface with the M16 extractor. Lastly, we opened up our mount screws to 8-40.

Once we got the action lined out, we started with a #3B Bartlien contour barrel. We cropped her back to 17", crowned her and threaded her for a Holland brake. I suggested the Holland as I knew she'd be a handful.......

Next, we threaded and chambered her. After all the machine work was completed, she got a coated of Burnt Bronze Cerakote. We gave the bolt flutes a contrast in Graphite Black Cerakote, along with the bolt handle.

Lastly, we used one of Norm's stocks from Royal Arms. Once fitted, we made pillars and bedded her. Lastly, she got a high gloss finish.

Below are pics of the build.......

Good look at the action and bolt after coating......

The finished rig.......



Here she is as we rigged her for shooting. Rigged with a Vortex Viper PST FFP 2x10 in Vortex rings and Harris bipod. Weight, as pictured was 8 pounds on the nose.......



Next, we loaded up Hornady brass with the 180gr Nosler AB for testing. Seems like the hotter you ran her, the better the numbers got. Our hightest laod shot was just shy of max data and netted 2678fps with an ES of 10 and an SD of 5. Not bad and the accuracy was there. She wasn't quite as bad to shott as I thought either. The big Holland tamed her down.......

Here's our best group of the day........



As well, we got some video for you guys as well. Not too bad for a boomer.......

We ran the laods seated at a generic ten thousandths off the lands. A bit of tinkering and I see good things to come.......

It is not too late, but I would add two hardened dowel pins to the scope base. Wise investment with a boomer.

In 1985 the rock band Heart had a big hit, "If Looks Could Kill." Well, w/ that classic song in mind, I anticipate this "boomer" will be a "killer." Big Grin I'm looking forward to some good hunting stories to come from this "killer!" thumbup


Good luck and good hunting.

Very nice. The finish is outstanding. I really liked my 338 JDJ and wished all along that I had something like that in an XP. Everything I shot with my 338JDJ was dead right there. That rig you built is running a lot faster than my JDJ. It should be good out to 300 or 400 with that Accubond.
Great build. Giving me some ideas again. devil

Thanks for the kind words fellas!!

Mike, the .338 RCM running the 180 AB will be hard on anything ya turn it loose on. With the AB traveling 2678 at the muzzle, running the numbers on my ballistic app, she'll be good out to about 425 yards for minimum velocity of 1800fps.

I was really pleased with how it turned out overall and pleased even more with how it shot. Recoil wasn't bad, at all with the big Holland. When I talked with and suggested the .338 RCM for the build, I figured she'd be the ticket in the shorter barrel XP. She's all you could ask for, without a doubt.

The customer and I will be stringing a few XP'S out this winter on an upcoming hunt. I'm anxious to see how the .338 performs.

Wow that's nice work. A bolt action SP is on my short list, but it will take a couple years for me to get one.
