LRI pre-fits make load development easy.

It's on my checklist. Question: what's your recommended torque setting on a barrel nut?

With steel on steel parts and the relative low vibration of this gun (compared to a semi auto with stuff bouncing all over) I wouldn't think a guy would need more than 50ftlbs for the RPR. If a connecting rod bolt in an engine will stay together at that load, I have to think a barrel will too.



 
I should be more than O.K. then. Need to run some rounds down the barrel.
Tusen takk, Chad. (Norsky for "Thank You", compliments of my Norsky bride. Married 31 years today.)
 
Happy 4th! I had no keyholing from the Black Hills or Creedmoor brand ammo through my LRI barrel today so that's positive. Still the best group was roughly 1.25" (167 grain Creedmoor brand) most around 2" not what I was hoping for. Head space is good, everything seems in order, shooting off a stable set up with my competion Nightforce. I'll call chad this week to see what advice he has.

It was a beautiful morning to shot!!

I found the video, thought you might get some benefit from it.

(The worst day at the range is better than the best day at work!)

Just a thought from personal experience. Running a radically tilted bipod especially on carpet has a tendency to cause a muzzle rise on recoil (foot skip). Ideally, the bipod needs to be straight up and down and allowed to move slightly in a straight back pathway. The feet should be planted firmly and not allowed to move, let the movement flex at the top hinge point. I have never been able to get tight groups from a forward tilted bipod, at least not like having it properly set up. To test this, try shooting over a front bag instead of the bipod. Take a video of the muzzle during a shot, then slow it down and see what the muzzle is doing. Take the time to watch the youtube video of MARK and SAM where he does an extensive analysis of how to use a bipod in the most accurate fashion. This guy shoots at 2k-4k yards and is good. Might be something to try to rule out operator methodology errors.

Thanks for the tip, I don't have an issue with my JP 308 or Seekings 6.5 off the same Bipods but Ill give it a try anyway...maybe they will tighten up even more!
 
Anyone having luck with the 123 grain bullets out of the factory barrel. I've posted on here a little bit back in the thread and I've got my 140's even tighter. Thought I had a load for 123 eld's and 123 sst's but I think my barrel just doesn't like them. I worked up some super consistent loads with 3 different powders 4 loads per powder in .3 grain increments w/5 shots per load, which normally makes for a good load out of the testing, but not this time. All loads were Hornady 123sst seated to 2.710" *from the book, with Hornady brass, and CCI BR-2 primers. Everything the same but powder. Anyways after 60 shot I ended up with a "maybe" 38.0gr Varget that put 4 in the same spot and gave me a flyer. The others didn't even hold tighter than 1.5" groups. Now I had some of my 140 loads on hand and confirmed my setup was solid by putting 5 touching "everything was at 100yds 2.7mph wind from 9'clock". This was going to be my Coyote load......but.... Anyways I'll load up some more of the 38.0gr's of Varget and zero. I'm actually going to call some summer dogs this Saturday morning. Anyone have any idea's to try, different bullets in the 120gr range? I will try different seating depths but these ran smooth out of the mag and thats what I want. Later when I go to rebarrel it with an LRI I'll have them cut it for the 123s as I actually have more use out of that bullet than others. Not many places to shoot distance here in the Natural state and I hunt alot and like the velocity of the 123s for cold morning coyotes that I don't have time to range. Ok out.
 
OK guys, I need some help. I have been shooting Hornaday 120 AMAX out of my 6.5 RPR (factory barrel, 1500 rounds). I have switched to factory Hornaday 140 ELD (they shoot great). My problem is that I have limited access to a 1000 yard range (4 hour drive) so I haven't been able to get there yet. My ballistic program (set at 29.5 baro, 80F, 60% humidity, 0 wind 500 ft elevation) calls for 8.6 Mils. No, I have not run the 140's through a chrono, but I did chronograph the factory Hornaday 120 AMAX and they came in about 8 FPS slower than the factory rated velocity (2910) with a SD of 10 FPS. My question is, does anyone have 1000 yard DOPE for factory Hornaday 140 ELD's? I know every gun is different, but what is the trend that you have seen? More than 8.6 or less? I have a competition coming up and could use real world data even though it is not my own. It is better than nothing at all. BTW, gun has a 100 yard zero and an APA brake. If you have MOA info please respond and I will convert it.


Thanks,
Bang

I'm seeing real world velocities matching the box out of my factory RPR, after seasoning the barrel. Initially velocities were quite low - to the tune of 50-60fps - but last time I busted out the magnetospeed I got 2713 average.

That should calculate around 8.4-8.8mils depending. JBM spits out 8.6mils for your data using the pre-loaded projectile profile.

I have used 120 SMK and 120 Amax bullets with 36.5 grains of IMR4895. During testing the 120 SMK was good for .4 groups with .34 vertical at 36 grains, and .5 groups with .37 vertical at 37 grains. Both of them at 36.5 grains are good for 590+ with a lot of Xs 60 round mid-range prone scores.

It is not the screaming flat max load, but near max the groups opened to 1.2 with .75 vertical.
 
Had another trip to the range with my 308 RPR. I'm amazed at the groups. I'm using freedom munitions factory new 168 gr Amax rounds.

Here is the plan for the pelican now that I have glass on my 6.5. The 6.5 will be heading to the range next week for its maiden voyage.

That's a great idea if it works. I've been hesitant on a pelican due to cost even though I had one previously for a 50 BMG. Those who own one, do you think the handles will hold up long term to the weight when carried with an AIAX and an RPR?
i also placed an order through LRI for my 24" 6.5 barrel today, and installed a Gen 3 Magpul for my RPR. FYI Universal Mania has Gen 3 PRS for 196. I was hesitant due to lack of publicity but no issues arose.
 
Pelican cases and their different setups are awesome to look at. However, I could only justify spending the money and effort on one if I flew to hunt or compete with the rifle it cased. For now the RPR just goes in the trunk with the range bag
 
I love the pelican case. I found a great deal during Black Friday from Amazon. There is also a great thread on AR15.com about using a hot wire cutter to make it look nice. I have extra foam panels that I ordered from another company to enable me to use the same case in many ways.

Here was my first attempt with the hot wire cutter.

Truth be told I have no earthly idea why your gun is splattering bullets like a shotgun. Do you have a brake on it or any other type of muzzle device? Anything is certainly possible and LRI is not infallible. I would have to see this thing before having any kind of speculative guess.

As for a 5 day lag, let me put this into perspective: If I sit on my ass and answer email after email after email it does absolutely nothing to ensure I get bills paid. We have a phone number gents. I plainly list it at the top of every single page on our store. We have 5 lines coming into the shop. We answer it when it rings.

Give us a call and lets get you tuned up.

-With the pending holiday, the full throttle schedule we've had since the 1st of the year, and a pending "big deal" that if it comes to fruition we'll be going nuts, I kicked everyone out till Wed.

4 day weekend at LRI. A very rare occurrence.

After rechecking headspace, scope mount and switching to a bag instead of my Bipod my groups tightened up considerably! Thanks to everyone that pointed me in the right direction. LRI barrel is living up to it's reputation. The wind kicked up so I quit today but the 2 groups below made a believer!

^ Are those your handloads?

Nope, 1 was FGGM 168 the other was Creedmoor brand 168 grain....forgot to add those were 5 shoot groups! I'm looking forward to my next trip with some hand loads, 175 grains FGGM and creedmoor were not as tight. Next decision I need to make is Break versus suppressor ...or neither.

Excellent results. In high precision, everything matters, gun, barrel, scope, exact duplicate rounds, shooter, rest, the temperature, the wind, and on and on.... That's what keeps it fun!

 
Why not both?

I'm thinking along the lines of what will be most beneficial for accuracy. Has anyone tried the LRI break on their LRI barrel? it certainly would look sweet and the mounting system looks intriguing. As to why not both, that's possible my surefire socom break/mount is affective ( new Sig 308TI has a mini break in the mount but I have not tested it yet because it just was freed this week) just wanting to learn more from other owners about what works best for them.

This is exactly what's drawing me into precision shooting. I shoot a fair amount but this is the first bolt rifle I purchased with the intent of seeing just how good I can get....I was.drawn in by the RPR price point even after adding the barrel it's not bad. This is kind of addicting and I'm sure it will eat up many hours of my free time!

I use silencer co brake and suppressor. Repeatable shift when suppressed.
 
In addition to the wrench, what else is needed to change the barrel?


I used a reaction rod when I did the Patriot Valley Arms barrel on mine. Worked great and was worth the money.Was like $60 at Anarchy Outdoors. Past that, just an armorers wrench and a go gauge. Pretty simple deal to do.



 
So I was in the market for a new bipod and decided on the Sinclair Tactical. With features that my Harris didn't have, such as an adjustable wide footprint, locking legs, quick adjust or just loose cant, it seems like it should be pretty awesome. They sell a QD rail mount for it too. Can't wait to test it out

Had not seen that one before. Very nice!
 
Anybody out there with experience using AICS, Accurate, or any other type of aftermarket mag for the RPR? I got some of the new pmag AICS knockoffs and there is quite a bit of play in them left to right when inserted in the mag well. Anything out there fit a little better? Every now and again I get a round that wont feed right. As long as im smooth on the bolt and work it at a decent pace every thing seems to go off without hitch. So, maybe the feeding issues are user error?

Anyone checked out the new Ruger AICS pattern mags? I'm going to be loading for my 6.5 GEN 1 and want a mag or two that I can squeeze maximum COAL and still feed reliably. I know the metal AR mags have a smidge more room than polymer, is it the same for AR-10 pattern mags? I'm also thinking about picking up a 20 rounder, but that will mostly be for looks.
 
Added the Vtab to the stock today. This thing is an amazing piece of machining. Works great. I could never get quite comfortable with the stock in the prone. Being able to move the butt pad higher is really cool. Has 12 degrees of cant also. No affiliation. Just think it's a great addition.

Just push the button the side and adjust up or down.

The factory buttstock is garbage.

How does that cheek pad attach to the stock?

 
Finally tested the new Sinclair tactical bipod and it is awesome. No need to load it, but you can, the wide footprint is super stable and doesn't hop, the quick adjust cant is fast and easy, and I noticed the same .5 MOA accuracy at 100. I would definitely recommend it.
