Try 38-39 grains of Varget with those 120’s. Worked better for me than the H4350

RUGER PRECISION 22 LR 18" RIMFIRE RIFLE - 8400 $349

Would anyone with a gen2 RPR 556 throw me a bone here lol

I have a box of 80 eld’s that I’m wanting to load up. Using those pills, what has your max oal to lands been? I’ve read all sorts of numbers, but almost all have been first gen rifles. Of those first gen, I’ve seen everything from 2.375-2.480. That’s a ton of difference. I’m not looking for loaded length, I’m looking for bullet touching lands. Thanks.

I haven’t played with the 80 gr eldm yet. But a Hornady case and oal gauge is one of the best pieces of reloading kit you can own. I prefer to make my own cases from once fired and sized to fit my chamber.

Yup I have and use a Sinclair, pre Hornady, gauge. Thanks.

What I want to know is what others are getting for their chambers to compare.

I need to try the 80 gr eld’s. I just haven’t got around to it. My 75 gr eld’s weren’t jump sensitive at all. I wound up with magazine length if I recall correctly.

Curi@ALASKANFIRE

Curious why you say "fool;" is there something wrong with the RPRs in Grab a guns inventory?
Or do you simply not like 6mm Creedmoor?

@RubiconJK
I finally got around to playing with the 80gr ELDM. My Ogive measurement was 2.885 so I loaded 2.880 the same as my 75gr ELDM's. Accuracy was good but pressure came up quick with the CFE223 I started getting pressure signs at 24.5grs with the CCI400 primer. This rifle always seems to show pressure quicker with this primer vs the Fed GM205MAR primer and a larger ES.

24.5grs = 2657, err, 2612, 2693, & 2626 avg 2650 ES 81 SD 32 Group 0.629
25.0grs = 2766, 2752, 2749, 2773, & 2702 avg 2702 ES 71 SD 27 Group 0.406
25.4grs = 2801, 2791, 2826, 2772, & 2844 avg 2806 ES 72 SD 28 Group 0.662
I decided the next load up was to HOT! at 25.9grs.
I'm going to try the Fed primer next to see if I can get the extreme spread down and try Varget. I think CFE223 is flirting to much with pressure with the 80gr ELDM.

lol none of the above

How are you measuring length?

With the Hornady OAL gauge. Col is measured with straight calipers.

You’re loading .223 to 2.880”? The case length is 1.76” and the 80 ELD is 1.16” OAL. Pic of loaded round?

I didn't subtract the 1.005 for the Hornady tool. My coal is 2.410. Do you fallow now?


I didn't have a loaded round yet. I'm gonna go to town and get some Varget. I didn't have as much on hand as I thought I did. Clear as Mud?

ALASKANFIRE - cool thanks, just picked mine up from the FFL.

QUESTION for you & all 6mm Creedmoor reloaders:

For the RPR, what full length resizing die do you think is best?

Redding or Forster both make terrific sizing and bullet seating dies.  I really like their micrometer bullet seating dies as they help reduce bullet runout compared to a typical RCBS bullet seating die.  I find that runout is a combination of a bunch of factors in addition to just the bullet seating die, but I don't want to derail the thread with a bunch of unnecessary reloading info.  It is easy to give way too much information that many people aren't interested in.

I use the Hornady die.

I am strongly considering the Hornady die because:

Hornady largely created this cartridge and

They seem to be among the first and main loaded ammo manufacturers and

Ruger seems like one of the first on board to make 6mm Creedmoor rifles.

I'll buy a Hornady sizer.

Eventually will probably ream it to 243, so I don't want to invest a ton.

I like the Hornady dies to especially the Micro seat stem.

These were the 80gr Hornady ELDM. Out of the .223 RPR wearing a Hawke 6-20 scope and AWC raider suppressor. I think the little rifle likes Varget a little better than CFE223.

Thinking of putting a Magpul PRS Gen 2 on mine.  AR15 model or the 308?

I just put a Gen 2 .308 version on mine.  Looks fine and no issues.  I just had to install a rifle buffer tube.

Great.  Thanks.  Does the other model fit as well?

It will as long as you use the matching buffer tube. Use a 15 buffer tube and the prs stock will fit. The 10 buffer tube is longer because of the larger BCG.
ive got a gen 3 on mine. Love it.

Awesome thanks

What are you guys running for Rings?  I am torn between Vortex Tactical or Precision set of rings.  I am also look at the Mount.

The precision rings will be better than the tacticals.

I use a LT OBR Mount with. Gen 2 PST 5-25x. Perfect height and makes removal and reinstall return to zero simple.

https://www.seekinsprecision.com/product/scope-rings/scope-rings-30mm-tube.html

Vortex Precision - 1.45" height.  I don't remove my scope, so there was no reason to go with a mount.  Whatever you decide on, just remember that you need tall rings.  Some people forget that the RPR is an in-line-style rifle, and try regular rifle rings.  If it works for you on an AR, it should work on the RPR.

Finally got around to making it out shooting this weekend. It sure is rewarding to shoot some tiny groups with this rifle. Only issue I had was a guy next to me shooting an ar pistol with a monster muzzle blast who put three rounds on my target before I mentioned his zero needed adjustment.

I ran a few different bullet/powder combos through to see what shot best. I bought a box of 80eld’s, I also had some rmr 69’s, and some 70 vld’s on hand, so I loaded them up as well. I use cci 450 magnums on the tac and cfe as they seem to ignite the ball powders more consistently.
69rmr’s were on top of 23.0-25.4 Tac
70vld’s were on top of 23.0-24.8 CFE
80eld’s over 22.5-24.5 Tac and 23.0-24.5 CFE
All groups shot from a bench, 100y range, weather was 38-45F, 1-3mph winds. Basically a perfect day to shoot. Really impressed with this RPR so far, especially considering none of the cases were fire formed in the chamber.
Best groups were:
69rmr 25.4g Tac .276”
70vld 23.0g CFE .486” (3 rounds at .198”)
80eld 22.5g Tac .436”
80eld 23.9g CFE .141”
Pics or it didn’t happen you say, no problem.

Great shooting! Also thanks for doing some of the leg work for me when I get back into reoading for my 223 RPR in a few months. This will save me some time for sure. Have you tried any 8208 XBR powder?

Try the Fed GM205MAR primmer I’ve had really good luck with it with CFE223.

I have tried the search feature, but to no avail.  Also searched with google fu which is weak.

I have my 6.5 PR with a nightforce ATACR 5 X 25.  Newly mounted and will have a chance to do a sight in this weekend.

Where should I set my zero?  Mount is a Spuhr 0 moa.  Saw some that set it at 100yrds.  In the past with my hunting rifles I have set a zero at 25yrds which usually gave me a zero at around 200.  But this is with a 30 year old Weatherby .270 MK V and a Leupold 3 x 9 VX II.

Thanks for the input.

It’s all about your personal preference. I zero all my scoped rifles at 200.

If you zero at 200 and assume an 8” vital zone with the 6.5 you’re going be basically be point and shoot out to 300.

Hmm, I just bought a cheap AR-15 buffer tube from Brownell's.  Worked fine with the AR-10 PRS.  I believe manufacturers make up the difference in bolts with the buffer, not buffer tubes.  I've never had a problem swapping stocks around between large and small frame ARs.

Actually both tubes and buffers. Yes you can find 15 combos that will work but a standard 10 carbine buffer is shorter than a standard 15 carbine buffer and a standard 10 carbine buffer tube is longer than a standard 15 carbine buffer tube. Rifle buffers are different lengths as well to work in the same length tube with a longer 10 bcg. Aftermarker buffers and springs make mixed workable combinations possible.

Got ya.  I knew carbine buffer tubes could be different lengths but since we were talking about a PRS rifle stock I assumed we were talking about rifle tubes.  Guess I should have clarified that.

There is no difference in rifle length tubes between the AR10 and AR15. They use different buffers and springs only to accommodate the difference in BCG lengths. This is easily verifiable with an easy google search.

Also as far as the Magpul PRS stock, the difference between the AR15 and AR10 models is the distance from the cheek piece to the charging handle to allow for the longer handle of the AR10. That’s it. Again, easily verifiable.

The cheek pieces are different sizes. The AR15 one is wider.

Or longer? We don’t measure rifles by overall width...Which means the distance to the charging handle  is different. Because one is longer  than the other. Or is one shorter? 😉 we said the same thing, I was implying they were different, assuming everyone knew that was why the distance was different.



Magpul used to sell a conversion from one to the other as well. I installed a new gen three on a rifle the other day at work, and it was really nice compared to the older ones. And it can attach to a carbine tube or a rifle tube. Now I do not know if it will attach to an Armalite AR10 carbine tube, that’s longer than a AR15 carbine tube. But there are a few 308 AR’s that use a regular carbine tube... so there’s that. My RPR has had about 5 different stocks on it so far, and the old PRS stock has worked the best for me so far.

I have some xbr but it’s just a bit too slow for my liking. Using the hornady load data as my guide, xbr was on average 150-200 FPS slower than the powders I chose. Normally I wouldn’t mind a slight drop in speed, but I’m planning on using these loads for medium range prairie dog work. When the wind gets to blowing, which it always does on the plains, I need every bit of velocity I can throw in a case to get those heavies out there and on target. The Varget data was basically on par with the cfe, the only difference being the cfe is much easier to meter and uses less cartridge space in effect creating a slightly larger combustion chamber. That’s where the magnum primers really shine, being able to fully ignite the sphere/ball type powders in a shorter 18-20 inch barrel.
I have a ton of cfe, Varget, and tac in my powder stock, so I figured I’d use some to give this new ruger a healthy dose of speed. I used book listed max charges and didn’t even start cratering or flattening primers so I’m confident I could go higher, but why. In my other bolt guns I easily get 8-9 loads on a batch of new LC or Hornady brass before the pockets start getting loose so I’m expecting about the same from this setup. When I shoot short range, 200/300 yard small bore matches I exclusively run Lapua brass and it nets me 13-15 firings with close to max listed loads. Btw all my match guns are 223 or 223ai chambered just to keep things easy.
Overall I expect to shoot about 3-4000 rounds a year through my bolt guns, which I rebarrel every 10k rounds regardless of how bore looks. I might step up and put a new barrel on the RPR before that just to get it out of the way. But with groups like I’ve been getting it’s really hard to justify. I have been looking at options for swapping out the handguard, stock and trigger. But again, is the juice worth the squeeze? Especially since I’ve been pretty happy with the adjustable stock that comes on the rpr.

Anyone run a lancer CF handguard or dv8? Any pros or cons? I really don’t like the feel of the seekins and the midwest is just ok. Don’t really care about keymod vs mlok as I use all picatinny attachments.
How about triggers, is the timney best option out there or ?? I’m pretty much set on a two stage with 1-1/2 pull weight if that makes a difference.
Advice and experience is appreciated.

What slings have you guys found to work well for this?  I don't plan on hunting with the rifle, just dipping my toe into some precision matches here locally

I bought one yesterday for $795.  I have no use for a 6mm Creedmoor, so promptly order a Bartlein 6.5 Creedmoor barrel from WOA.  $1300 for a Bartlein barreled RPR isn't bad at all.

Okay fellas, had a chance to sight it in and I really like this rifle.  Had my Omega can on the end and only got out to 225 yrds for this time.

After about 50rds, the damn bolt tool came loose and then proceeded to rattle around after about every 8 shots.  I mashed it back in but this sucker is just falling out.

This is a Gen 2 rifle in 6.5 CM.  Do I have a bum bolt shroud?

Get an Anarchy Titanium bolt shroud, it fits better.

Anyone shoot any of the Federal Gold Medal SMK 140gr out of their 6.5's?  It's $20 cheaper a case than Hornady ELD-M so I was curious what results some folks have had

I may go that route when I shoot this barrel out.

I shot some of it a while back at 300 yards. The Hornady was grouping better.

I have to ask, is there any reason for me to get a 6mm or 6.5mm creedmoor Ruger Precision rifle when the longest range I have is 300 yards. I have a .223 RPR and also shoot a 6.5 Grendel AR. I don't have any targets to show but they are both really accurate with the Ruger being out front with hand loads.

Also, was there a reason for Ruger to stop production of the .223 RPR?

I only shoot my 6.5 to 300 mainly.

The round suppresses well, it accurate and looks cool.

If being used for target and/or steel shooting, IMHO no.
