Thanks to Marty from Teppo Jutsu, I received my upper yesterday!  Curley Maple also provided a beautiful walnut forearm for the build.  I went a little different than some of the other builds, with a Larue billet upper receiver to match the POF 416 lower I built a few months back.  It was also supplied with a Shrewd MB, and for the stock  I went with the Ace Skeleton.  

Over the weekend I loaded a number of different rounds, all of which resulted in very good hunting accuracy using the BUIS and Bushnell Trophy Red Dot.  Three groups with the red dot were clover leafs, all touching, at 50 yards.  Not too bad considering there was no magnification at all.  None of the groups were larger than 2" at 50 yards, including the groups fired with the BUIS.  I'd love to see what I can do with a 2-7 power scope on top.

The only issue I had was the Barnes 250 gr FPHP not feeding well, as they got hung up on the center point between the two M4 style feed ramps.  Fired one at a time, they were one of the groups that were extremely accurate.  Does anybody ever file that sucker down to nothing?

After 50 rounds, sighting in and testing rounds, I have a small bruise on my shoulder.  I think I'm naming this rifle "Thumper".  The "BOOM" is addictive.

I'm on the dry side of the state field tesing my rifle on elk, and once I'm done I'll post few pics.

In the mean time, here are a few photos of the .458 SOCOM round compared to the .45-70, .44 Rem Mag, and the .223, plus how the rounds fill out a mag.

 

Oh. My. Gawd!

What's the recoil like? Mag capacity? Quick followups? etc etc Tell us all about it! And pics if you got 'em!

They sure do move the earth... always liked the concept. Great AAR

I was on the near receiving end of one of those big bore AR's a while back.. down range cleaning up and this fellow was trying to clear his rifle(mechanical, the disconnector wasn't releasing the hammer for the sear to grab it), and when the hammer did release it dropped..

Nothing quite like being showered by rock and dirt from a 400 gr .50 bullet hitting the ground 5 feet away

Recoil is like a 12 semi-auto with 3" loads, fairly stout, but controllable.  Didn't try any speed shooting, but with the sight I have I think follow-up shots should be pretty easy.  A 30 round mag holds 10, 20 rounders 6, and 10 rounders 4.

Where was this? I sure would stay away from fuckers screwing with firearms while anybody is downrange.

Here are a few photos of the finished product.

Nice looking rifle!

I like it

it's like a Fudd gun turned to the darkside

Fudd-tactical was what I was aiming for.  I have some 500 grainers, but haven't loaded them yet.

Next LCR I'll make a point of loading up plenty of rounds for folks to shoot.  It has a satisfying THUMP.  Not sure i'd want to bump it, though.

If you want one just send Marty your money, and wait 7 months or so.

Bushnell Trophy, $159 at Midway.

Very nice.

All I know is that it throws a 300 grain bullet around 2,000 fps, developing 2,700 foot pounds of energy.  A .30-06 with a 15 grain bullet has about 2,900 fps, and 2,900 FPE.  Certainly acceptable for deer, bear, and elk within 150 yards.  Think of it as a .45-70, in semi auto format.
