RPR 6mm Creedmoor freebore?

[fatelvis]

I too recently purchased a RPR Gen 2 6mm creedmoor and I am having the same issues. I used factory Hornady Black 105 bthp for barrel break in and they are seating into the lands. Tried 108 ELD_m and they are touching the lands at 2.632 coal. 2.083 @ Ogive. I have contacted Ruger and have yet to hear back from them. I have a RPR 6.5 gen 2 That I have had no issues with. I spoke to another shooter that said he also found issues with RPR recently.

The solution to my non-existent throat, was to fire the entire Tibb’s Final Finish kit through the rifle. It pushed my lands forward the perfect amount, to seat bullets normally, and seemed to improve accuracy and ease of cleaning to boot. In mid range F-class I was at Expert classification, and with this rifle I I’ll be shooting at Master level this year.

Thanks for the information, I just ordered the kit and I hope to achieve the same results as you. Otherwise this RPR would have to make a trip to Gillette, WY Via USPS or UPS. to be worked on. I really dont want to make it a paper weight even though it would look great as one.

I've got mine shooting pretty well finally. I think the Tubb kit worked but it continues to seemingly improve as the throat wears in even more. I went through H4350, H4831SC, berger 105's, nosler RDF's, hornady 108's and eventually came back to RL-16 + SMK 107's running a fair bit hotter than I had expected. Its not quite as good as my 6.5 for groups, but good enough as backup for competition. I'm happy if i can get a gun below .5 on avg, that means a gun is shooting as well as I've ever been able to shoot. So .5's into low .6' like target below isn't that far off anymore and I can still play a bit more fine tweak seating depth +- .003, etc

Note below is pretty hot in starline cases, no pressure on the cases/primers but at 3100FPS+ but we'll see how long the starline brass lasts (in addition to the barrel).

Hmmm,

Have not loaded for my RPR yet but you guys have me all concerned. I have 160 rounds down the pipe with factory Hornady 108 ELD's, no issues so far and I intended to load the exact round I have been shooting, tweaked for a little more accuracy if possible. I have thought about other bullets, all mentioned here prior. My question is : in reference to the image attached should I bother with trying other loads or is this about as good as I can expect from this rifle. The one flyer on the right was me, I called it, jerked, just as the annoying knucklehead next to me with the bullpup .308 and muzzle break fired.

Can you lay down 5 groups just like that with the factory 108 ammo? If you can, then I'd probably just keep shooting that (aside from fact you can reload for less) or try and replicate that load to start and then just tweak it a bit and see what happens.

I've never gotten either 6.5 or 6.0 RPR to shoot consistently under 1MOA with factory ammo but have gotten 3 different barrels into .5's consistently. Generally you should be able to improve on factory loads with handloads, but if you can do 25 shots that all look like that, it will be a lot harder than a gun that really only holds .8-.9 with factory ammo.

 

[rr2030]

That was all factory ammo, only ammo I have fired as I am accumulating brass. I m not unhappy with this group it is average for this rifle. I just want to duplicate / tweak the load for a little better accuracy, especially beyond 600 yards.

How do I know if I have a gen 1 or 2 and does it matter?

Gen

How do I know if I have a gen 1 or 2 and does it matter?

Gen 1 rifles have a top rail on the forearm. Gen 2 rifles do not.

 

[dnellans]

if you've got a 6 creed then its a gen2, i don't think the gen1's came in 6 creed did they?

interesting to hear another rpr user with virtually identical symptoms.

43.5 of rl16 gonna be smoking hot, that’s way over max values i’ve seen. be careful working up, from my testing that high would put me over well over 3200fps with a 24 inch barrel. interested to hear where you arrive for final load

I did a ladder test going up to 42.9grs of RL-16 using Berger 105gr Hybrids, CCI-450's, Lapua 6mm Creedmoor SRP brass, seated -.030" jump. 42.9grs produced 3175fps with my 24" RPR factory barrel and no pressure signs. But I agree with others on being careful! I too have a short throat RPR, somewhere around .090" or less. Not a huge issue for me at this time, you just have to check every bullet (brands and weights to be used) before loading with gauges for there touching the lands measurement so as to know your max length for reloading. I don't buy factory ammo, but if I did I would pull a bullet and check in the same manner to confirm if they touched or not for safety reasons.

No it did not, only in 243, 6.5 Creedmoor, and 308.

Thats crazy - thats quite the f*ck up by tubb. Glad you noticed it upon seating at least!

Wow, from a Tubbs kit? That's crazy, if I ever did use one I will definitely be checking to see for quality control. Will pass this on to my buddies. What did Tubbs say about this issue?

In mid range F-class I was at Expert classification, and with this rifle I I’ll be shooting at Master level this year.

So the Tubbs kit is so abrasive that it removes a large amount of throat area?

 

[AckleymanII]

Not only length wise growth, but dia. wise also.

In the 6.5 creed with the 140g-147g class of bullets, I have always got better accuracy with AA4350 than H4350.

It depends on how many of th grits you use. If the rifle just needs a little clean up they recommend just using the three least aggressive bullets. It will polish but not remove much of anything for the throat.

First I want to thank you for the info on the Tubbs Final finish. It worked very well. I ran the last three bullets and then did the last cleaning. It was like 'MAGIC'.....HOORAY...!Now instead of pushing the factory hornady 105bthp into the lands they actually have some breathing space. I have not started load tests as of yet. But plan on doing so quite soon. The weather and J>O>B have NOT been cooperating very well. .... Little Brother will breathe fire soon I hope. Thanks again Elvis

I have not loaded Starline for my 6mm, but I have used on my 6.5 rpr and had great life out it. It had less case volume than Hornady brass and about the same volume as Nosler brass. Pushed a 140 ELD-M at 2986-2990. Very hot load developed for one mile.

Hello everyone. Wish my first post was positive but I appear to be experiencing this same problem.

I just got into the reloading game and as a function of the learning process I began to suspect something I noticed about my RPR may be more than just a "break in period". Looks like I'm shoving my factory Hornady 108 ELD"S deep into the lands. I had to hammer the round out of the chamber and immediately noticed the marks all around the bullet.



I measured approx. .30" of Mark's from the edge of the case to the end of the marks.

This 6mm RPR has maybe 200 rounds through it and I'm thinking I should send it back to Ruger for correction. I certainly shouldn't have to pony up for a repair on a brand new gun.

I feel your pain. I also had the same problem. My solution was the David Tubbs Final finish system. It added a little more work to my already hectic life, but I was very pleased with the results. I wanted to send it back to Ruger too. But with limited time I also wanted to continue loading test loads. So I went ahead and purchased the kit. I wish you luck,

A few of us had the same problem with our 6 Creed.

I used the Final Finish kit too. Worked wonderfully, the rifle now has a normal length throat, and it's very accurate.
