We might as well have a single thread for our LaRue .260's since they're shipping and will be in our hands soon. Feel free to post anything .260: unboxing, pictures, optics, suppressors, range reports, load data, questions, etc., etc.!

Here's the description of the PredatOBR from the LaRue site:

LaRue Tactical PredatOBR 260 Remington

The PredatOBR 260 Remington is the ultimate lightweight long distance rifle. The most remarkable feature of the PredatOBR is its ability to be completely “broken down” and stored into the optional Rollup Bag and Toolbox. The PredatOBR handguard has a locking stainless steel QD Lever system on each side. Once the levers are released, the handguard slides off of the upper assembly in seconds. The PredatOBR's barrel can easily be removed with the supplied PredatOBR Barrel Wrench, unscrew the Barrel Nut from Receiver and pull the Barrel Assembly free from Receiver. No need to remove the gas tube, gas block or muzzle device. Reverse the process to reinstall. Hand-tighten Barrel Nut and torque approximately 1/8-turn past hand-tight (Approximately 40-50 foot pounds). Once reassembled correctly, the point of impact (POI) shift will be 0.0 to 0.5 MOA of the original.

Barrels are chambered in 260 Remington, and feature rifling in a 1/8 twist rate. All barrels are threaded in 5/8 x 24. Like the OBR and PredatAR riles, LaRue has eliminated the conventional AR barrel nut and bolt the handguard directly to the proprietary upper receiver, creating a true “free-float” barrel. The handguard does not touch the barrel or barrel nut at any place. The zero-MOA upper rail provides plenty of room for weapon-mounted night-vision day/night combinations. Both the upper and lower are CNC-machined from billet aluminum for the optimum fit and consistency. Even though it has been lightened certain features, there is still additional material in strategic areas to achieve maximum accuracy.

The PredatOBR has threaded stainless-steel hard-points over the entire length of the handguard at the 3, 6, and 9 o’clock positions. These hard-points have an integral spine built-in for structural support. Provided with the system are three 3-inch MIL-STD-1913 rail sections that can be positioned anywhere along the handguard, per operator preference. These rail sections are attachable/detachable using a supplied tool (Torx® T-15 wrench). The rail sections are CNC-machined from billet aluminum. This robust solution provides a perfect precision mounting space for aiming lasers, illumination and bipods.

The PredatOBR's Port Selector Technology™ (PST) gas block is adjustable, to aid in the optimum function when using a sound suppressor. This special gas block contains a dual port mechanism that is operated by rotating a lever from one side to another. When the lever is rotated to the right-side of the rifle, the gasses are reduced, to compensate for the extra blowback created by the suppressor. When rotated to the left side, the gasses are increased for use without a suppressor.

The LaRue Tactical 6-position Retract Action Trigger (R.A.T.) Stock comes standard with every PredatOBR. It is ergonomic, has protected control surfaces and contains a set of cleaning rods in an internal compartment. Since the height of the 12 o’clock rail is at the optimum position, there is no need for a cheek riser as part of this system.

About LaRue Firearm Accuracy:
LaRue accuracy is known world-wide. The accuracy of each LaRue Rifle is proven at our 100-yard tunnel using match-grade ammunition. No LaRue firearm can leave the facility unless it obtains accuracy of less-than 1 MOA (1.047”) at 100 Yards. Each firearm ships with a copy of a 3-round group obtained from that actual firearm. While we guarantee the rifle is capable of sub-MOA accuracy, we can not guarantee the end-user will be able to shoot sub-MOA…since we have no control over shooting proficiency, familiarity with the system, ammunition choice, environmental factors, etc. LaRue firearms are precision instruments that require discipline, training, proper ammunition and maintenance to yield the best results.

Updated Index – March 13, 2018 – Links Verified and New Discussions Linked. Commentary added offering the benefits of the findings / wisdom of the thread.

Disclaimer - With any thread, context is gained by reading the entire discussion.  You may have to read posts around the referenced replies to gain the proper context. Also, some posts contain multiple discussions or topics so they may be indexed in one category but contain multiple content. I did my best to capture the differences in the Index, but there could be exclusions.

Drop me an IM if one of the bookmarks is bad or incorrect and I'll fix it.  The index, which is current to March 2018 and Page 55, will be updated as new range reports / posts are added.

2. .260 Ammo Sources. NOTE – There are a host of manufacturers making .260 Ammunition. Throughout the thread, people have primarily shot target loads. As a general statement, the tOBR prefers a milder load (2650-2750fps). Prime and FGMM tend to be loaded hotter while the Hornady and Gorilla tend to be loaded milder. Shooters in this thread have consistently reported the factory Hornady 130gr ELD-M has performed very well in the tOBR, in both the 18” or 22” versions.  People are also using the Prime with good results.

Applied Ballistics Munitions was rebranded as Berger Ammunition. They moved their plant from Commiefornia to Phoenix and will be back supplying retail ammo mid-second quarter of 2018:

Berger Ammunition

I’ve included Copper Creek as they have an option that allows you to order load development packages offering five differing loads to help you fine tune your development:

3. .260 Brass Suppliers. NOTE – You can purchase brass from a number of suppliers such as MidwayUSA, Brownells, Mile High Shooting (offers LEO/Mil discounts), Brunos, Natchez, Mid-South, etc., etc. Go to any of their sites, or those you may know, to shop brass. I’ve also included Alpha Munitions and Peterson as they make top quality .260 brass in the USA, in both large and small primer versions. Starline also makes .260 brass but we’ve not had any reports in this thread, as of March 2018, on their quality.

Alpha Munitions

Peterson Match Grade Brass

4.  Bullet Suppliers. NOTE – You can buy a host of projectiles on-line. I’ve only included four here, one for Shooter’s Pro Shop as they have some great sales on blemished brass and bullets (Nosler), solids from Warner and Cutting Edge and the JLK "Swampworks VLDs as a member in the thread has some to load and test. I've also included a review of the Warner Flat Lines published on the Hide, however, as of March 2018, no-one has reloaded or shot the WFLs, or any solid projectile such as Cutting Edge. As a note, the solids have a higher BC and fly flatter, which reduces elevation adjustments at long range. However, they tend to be longer than a VLD and will likely require single loading in a gasser, or deep seating of the bullet.

For those that aren't aware, Vortex offers a very good active and retired Mil / LEO discount.

I had the brass and some pills for a total of $135. Used LS9 and got $10 and still had to pay $7.95 for shipping.  I'll try again.

Not worried. Both of my tOBRs and my FDE came with targets that were easy to beat. Heck I shot a .227 out of one of my 18" 7.62 tOBRs.

Now I just need some ammo!

Anyone know if all factory 260 loads should be good to go in this gun?  I don't want to pick up a case of ammo only to discover  it is too hot and only works in a bolt gun.
I thought Mike p had mentioned this somewhere else but I can't find it now.

I was thinking the same with my question about heavier bullets. If the gas system is a +2, I would think port pressures would be manageable with commercial loads.

I'm also new to reloading, but I think H4350 is a slower burning powder that offers a more manageable pressure curve and could be better for heavier bullets. Using the Varget, a faster burning powder, produces higher pressure curves, with less of a charge, and may be best for lighter bullets.  However, there are other variables such as barrel length, powder burn rates, bullet type and weight, etc., etc.

I remeber someone saying that a lot of the commercial ammo, including FGMM, was a bit too hot for a 260 gas gun. It may have been in this forum but I want the say they were getting best results with handloads.

I just got that FDE .308 with a .110 test target. But out of all of my LaRue guns that was an outlier for sure. The next best was my 5.56 OBR I. The .3xx range and then my Costa with a .414 group.     I have faith that you guys will do better

You will get the best results with handloads 99% of the time.(Assuming you know what you're doing)

Someone just needs to call LT and ask them what commercial ammo they used for testing.
