Ruger Precision Rimfire

[Subwrx300]

Thought I might throw is up as a teaser....have been using it for about 1200 rounds or so over the last two weeks and it is GREAT! For those wanting a replacement trigger for the RPRF, at least one company is in progress with beta testing. I'm sure details will arrive at some point soon from the manufacturer.

So cool. Except removing my trigger group is almost impossible. Probably will need to remove material to take the old out.

Oh tell us some more... I read somewhere on some forum that some person was beta testing a trigger for some well known trigger manufacturer. Will it be worth the wait?

Yes. Definitely. Factory trigger is good but this is substantially better. Smoother, cleaner and lighter. Helped control break until exactly when you want.

Will be worth the wait.

Single or two stage trigger ?

Two stage... 8oz first and 8-16oz adjustable second stage.

When will someone produce a real chassis? One quality product could take this rifle from good to exceptional.

I think there is a market for a chassis but I'm not sure it would make a better alternative to other platforms. For the cost, a CZ 455 or even Savage have several stock options that make sense as they aren't adjustable from the factory.

Don't get me wrong: I for one would like to see some other options but the factory stock is pretty good value given it's features. But for some, I can definitely see reason/logic for wanting aluminum chassis or maybe composite stock if simply to upgrade what they already have.

I would likely buy an MPA or similar if they offered one to have a poor man's Vudoo...but I don't think the action lends itself to those options due to magazine shape and lack of lugs of any sort.

But Id love to be wrong about that! 😁

 

[quickdraw]

The primary selling point of the RPR was the factory chassis style system. If you chuck that then what is remaining is not worth building. If and that is a big IF changing the barrel and a few minor expense tweaks can get it to a solid 1moa rifle then maybe it's worth the cost and effort. If not then it's just a cool looking plinker or youth rifle.

 

[Frankr]

Random thought - wonder how much it would cost if someone brought out a chassis that used the RPRF action, free float tube, grip, trigger control group, etc.... just replace the plastic with metal and you added an AR15 buttstock.

This might solve a lot of the accuracy and feeding issues that people have. I can’t imagine it would cost much, kind of like the PMACA chassis for the 10-22.

 

[Travelor]

Before throwing money at this little gun, make sure it is shooting to your expectations. Mine has been through 4 barrels ( the first Ruger barrel shot poorly, the second Ruger barrel was defective per Ruger, and the third Ruger barrel is now shooting no better than a CZ), the last being a Green Mountain 18" and is now sitting in the chassis with freezer tape to aid in the "bedding" of the action to the chassis. It is now showing some progress to shooting well enough for a PRS match. I like the trigger and think for me this is probably the best feature of this infuriating beast.

How does it shoot now? About on par with a factory CZ, so I am through throwing money at this thing. The Ruger will be relegated to either the safe or be sold.

Dropped the money needed to buy a Vudoo V-22 and now I'm extremely happy with no need to do anything but enjoy this fine rifle. The Ruger will be religated to either the safe or sold.

 

[blacknwhite11]

I understand both sides of the argument. My line of thinking was most problems with this rifle could be solved with a new quality chassis or stock. I think one of the big benefits that is over looked is the ability to switch barrels easily. Match barrels and new caliber conversions would be cool.

 

[Sieg]

Bought mine with the intention of converting it to a .17HM2 for controlling ground squirrels in the orchard behind the house.

I couldn't resist seeing how "precision" the gun was out of the box. It wasn't, 5 shot groups averaged .75-1 MOA at 50 yds due to 2 random flyers per 5 rounds. Tinkered and tested for hours and improved the group average by approximately .15".

The gun has a weak ejection issue that leaves a case on in the chamber unless the bolt is racked like rapid fire drills.

Shipped the gun back to Ruger and they replaced the bolt and barrel, but did nothing about the ejection issue. Accuracy is in the .4 - .7 MOA range now.

Hopefully someone will step up and make a .17HM2 barrel in the near future as the platform is a easy maintenance functional tool for my intended purpose.

IMO the mistake they made with the rifle was naming it a precision rimfire.

But it's is shooting 1/2 moa now which I'd definitely call a precision rifle for a .22LR. Especially for a $400 rimfire.

It is disappointing though that so many people have had to call Ruger to get stupid fixes that seems like QC would fix before it became the customers issue.
They will probably have a Gen2 soon that address the common issues people are seeing (mag feeding, weak ejection, precision issues, etc). I still believe it's a great rifle for the value alone but understand how some are frustrated.

It's not a $400 rimfire anymore 1500 rounds of testing, 25+ hours of tuning/tinkering.

My Vudoo has effortlessly exceeded my needs for .22LR.

Hopefully someone will produce a reasonable .17HM2 barrel or someone will get a good deal on a RPR that actually shoots.

I keep working on Shaw, Green Mountain, Lilja, and others to produce a drop-in barrel. Not much trust in the ammunition suppliers at this point. Though CCI did have Anschutz build a .17HM2 test rifle for them. So I'm not giving up hope..... but will not shoot the round in a semi-auto again, only a bolt rifle.

Another option is to get a Summit action from Volquartsen and use my old and proven ER Shaw HM2 barrel from my 10/20 KaBoomer conversion.

 

[Travelor]

All the RPR needs is a barrel and magazine to be a 22 Mag or a 17 HMR as the bolt and chassis are already set up to move the fabled part #59 back to accommodate the magazine and the bolt stop can be removed to lengthen the bolt throw. I'm sure that Ruger designed it for this conversion as well as new rifles in these calibers.

The 17 HM2 has been kid of a step child since ot originally came out and ammo was very spotty for a while. I'll be surprised to see a barrel in this caliber come out. I have two rifles in the caliber and find it to be a great cartridge for "normal" length 22 actions.

What two rifles do you have in HM2?

I'm sitting on 4K+ rounds of .17HM2 impatiently waiting for the right rifle or barrel. I was somewhat surprised the round never gained traction, guessing it just wasn't macho enough for the vast majority.

I have 2 .17HMR's and an early Ruger M77/22WMR Varminter. My 27 year sage rat hunting hobby began with .22LR, then .22WMR and .223, then .17HMR and .17HM2, and now .17WSM. I'd have most bases well covered with a .17HM2. .17WSM, and .223. The .17's efficiently deliver high kill ratios and minimal ricochet liability.

My M77/22WMR pretty much got kicked to the curb though it's a good looking nicely made rifle, the ammo costs and trajectory performance don't justify it for the shooting we do of which the majority is 70-225 yds and 350-650 rounds per day.

 

[straightshooter1]

This Ruger Precision Rimfire comes with a factory "target" barrel, so like it's big brother the RPR, it's NOT going to shoot like a match grade gun when it doesn't have a "match" grade barrel. Being able to get this RPRF at a price point of $400 or less is a pretty good deal, as it does shoot better than all the other Ruger 22LRs. Though those ejection bedding issues are irritating to have to deal with. Now with a Shaw's match barrel and with the right ammo, I'm very pleased with how it shoots and makes a great training/practicing aid for my RPR.

Guys; I'm from Detroit and here we just love to take underperforming cars and change them into something special.

I have a 10/22 looked all around found a Nordic components chassis that I love; it's a good shooter. Wanted a bolt gun; saw that Cabela's had a RAR for a Black Friday sales price of $150. Picked that one up; dropped the Tupperware stock and dropped it into a MDT chassis and never looked back.

Then Ruger introduced the Ruger Precision Rimfire; to me it's just another platform to squeeze the most performance out of with whatever after market parts I can find. As stated by Sieg earlier it this thread; his Vudoo V-22 can shoot the eyeballs off a fly At 50 yards; but I get my fun out of getting unexpected results out of a junker.

I'm looking forward to the day where I can buy the Covette of 22 rifles but right now I can't justify dropping $2k in one lump sum on a platform that deserves a committed competitor behind the trigger.

Detroit huh? I've had this since 1989, nothing is stock and I've done 98% of the work. I get it.

That said, the Vudoo is the C7 Z51's of Corvettes.

My .17HMR RAR Target is a great gun, functions flawlessly and shoots .3" 5 shot groups at 50 yds. Though it is the replacement they shipped me for the first one.

Have put well over 1400rounds through Shaw barrel now and had a chance to shoot on calm evening just before dark. Shot at 100yds 70deg I was sheltered from wind. Also shot 2 other ARs and RPRF was my practice while letting others cool down.

Ammo used was SK Rifle Match and barrel was scrubbed clean about 50 rounds prior to this Target. (The 50 round fouling Target also pictured below but was shot over weekend under different conditions).

22LR groups are bottom two rows; First two cold bore shots when wayyy low but I have sort of come to expect that as wax/lube in barrel is cold and grippy.



Fouling Target at 50yds:


Bottom line: depending on how you measure, my 22lr is more precise than my 2 precision ARs! And it's getting better. At least for my rifle, precision is not an issue.

 

[Sieg]

Impressive, my .17HM2 Shaw barrel delivered too.

Shaw's response to my RPR .17HM2 request yesterday: Unfortunately we will not be able to help you with this request. We have not made any HMR 2 barrels is quite some time due to the ammo inconsistency.

Carson Lilja will supply a .17HM2 barrel blank for $370.

Green Mountain has blanks for $120, no drop ins. They'll do a run for 100 barrel minimum.

 

[Kisssofdeath]

I have a Ruger Precision Rimfire and find nothing wrong with it. I think the fully adjustable stock is great, if you bought a replacement butt stock what would you gain?, nothing I can think of, it's still gonna be plastic. Put whatever AR style grip you want on it. Built in 30 MOA scope base. Aluminum handguard with M-LOK's everywhere. The chassis is fine although it isn't aluminum it's still good. It's also a $400 rifle and for $400 for what you get is pretty good. This is coming from a guy who also has a 1710 in an XLR chassis. Every rifle no matter the cost has its place.

Are your speeds still fast? I shimmed the barrel a little bit and now I can eject live rounds. Bolt pressure doesn’t seem as tight anymore and my bolt handle isn’t rubbing the reciever either. Haven’t had a chance to get to the range the way it is now. Thinking about adding 2 more foil shims for a little bit more space but will probably try to shoot and see how it is at its current state. Shim thickness unknown because my mic said .0030 but after installing the barrel I think it crushed some.

 

[straightshooter1]

Upon swapping the factory barrel out for a Shaw barrel, I found it was very tight and could not extract an unfired round (per the warning on Shaw's website). That tightness was of some concern to the extent I was only going to use ammo that was highly reliable. I've now fired 850 rounds through the Shaw barrel and the bolt closing is much easier that before, though still tight. And, to my surprise, I tried on a few occasions yesterday to extract some unfired rounds to see if there was any damage to the bullet going on when round is being fed by various mags and they extracted just fine and without any issues. This was done using CCI SV, Federal's Auto Match and Lapua Center-X. So, I've feeling a lot more comfortable with the bolt closing and the extraction with this barrel.

PS: It's been about 500 rounds since I last cleaned the barrel, so I've guessing that maybe some lube has collected in the breach that helps with the extraction (even with rounds like Auto Match that have no lube on them).

I'd like to say they have but I think that may be due to weather. It's 55 now vs 75-80 when testing before. I couldn't say whether any speed change was simply due to ammo temp be barrel wear.

Really won't be able to test until I get a 70+ degree day in the coming weeks but those are about to be fewer and farther between.

Did the back side of your bolt handle rub the slot in the receiver when it goes into battery at all?

 

[straightshooter1]

Did the back side of your bolt handle rub the slot in the receiver when it goes into battery at all?

Yes, of course . . . as I would expect. In comparing that area of wear with the same area on my factory Ruger American .22LR (which has virtually the same bolt and set up), there's not much difference in the wear when I compare them. I my RPRF, I can't see, with magnification, what one might consider excessive wear. I do lube that area with Otters Choke Tube & Gun Grease and maybe that helps???

Mine was real bad compared to factory and leaving metal shavings in the action which in turn would be pushed into the barrel while cycling the bolt. I found the shavings last time I cleaned the barrel and claimed that to be the slight accuracy problem I was having.

A little off topic but can anyone confirm if a Precision Rimfire barrel will fit into a Ruger American Rimfire?

My educated guess is no; Ruger American uses pinned barrel (I believe) vs the barrel nut system used on the RPR.

Hopefully there is someone that owns both that can confirm compatibility (or lack there of).

 

[straightshooter1]

Subwrx300's guess is correct. I do own both and know that the RPRF barrel will NOT fit on the Ruger American rimfire action.

 

[Kisssofdeath]

Thanks guys, I figured that. I have both too and was looking for an upgrade then put the PT barrel on the American.

How many rounds did you put through it before you sent it back? What kinds of ammo did you try? My Er Shaw barrel accuracy isn’t much better than factory but it did keep the sd’s low with all types of ammo. Also sped them up about 30-50 fps, some 80 fps when compared to the factory barrel.

My barrel seems to shoot best after cleaned fairly thoughly through about 200-250 rounds ( 10 foulers needed to get back to correct POI). POI rises slightly over first 10 rounds and velocities level off around 1080-1100 depending on temp.

Bottom two rows are SK Rifle Match Ruger 22LR at 100yds.

How were the conditions that day? Looks way better than what I’m getting from it. Almost tempted to throw the factory back on and give Shaw back the barrel. It’s really hard to get anything to group smaller than 2 inches.

Pretty/very calm that day (shot at dusk 60deg) but I shot in a bit windier conditions last weekend and it shot fairly close to same. There were definitely flyers that seemed related to small gusts even in our fairly isolated 100yard range.

On a super calm day, it's capable of anything around .5-1moa at 100yds
With slight gusts it moves to about .8-1.3moa.
In fairly windy conditions, im happy with 1-1.8moa.

Ya not mine. Can’t find any ammo that will do anything like that. Best group so far was 1.7 in with 5 rounds of cci sv in 4-6mph winds. It seems to like that the best staying just under 1100 fps. Barrel is still fast with the shims but i now can extract live rounds now. Where I shoot it is normally gusty. I am just trying to achieve a 1 inch group at 100 but almost seems I went backwards with this barrel.

Does it shoot well at 50? With my factory barrel, I ended up scrubbing/*lapping* (if you can call it that) with Kroil, JB Bore paste and JB Bore Bright and VFG pellets. It did tighten up pretty significantly after that.

If it doesn't start shooting though, I'd call Shaw and get a replacement. I'm sure they would help out; they told me to keep in touch if I had any issues with accuracy.

Might be a pain in the ass, but maybe try single hand feeding for a few groups. I have a suspicious feeling that the feed angles of Ruger 10/22 mags might damage the pressure ring.

Controlled round capture and feeding is one of the major features of the Vudoo action amd, given the soft lead plugs we shoot, it makes sense that scraping/scoring during feeding could cause lots of issues at distance.

I'll run a test of hand fed vs mag fed later this week if I have time. We can compare results. Maybe 5 -5 shot groups single vs hand fed at 100yds (if wind cooperates.
