Ruger Precision Rimfire Accuracy Improvement Orderal

Bought a Ruger Precision Rimfire during Covid, because of it's adjust-ability and some articles bragging on it being great. I had the opposite result. Mine shot 6 moa out of the box. Tried a dozen or so ammo's nothing would work in the RPR.

Problems: clipped tips of bullets, failed to feed about 10% of the time, failed to eject about 20% of the time, rough bolt operation and hard to operate safety. Replaced with a wonderful CZ 457 Varmint.

Improvements:
1) adjusted magazine latch to stop clipping bullet tips
2) after seeing the atrocious rifling with a bore scope, performed a poor mans barrel lapping using JB Bore Paste and Kroil Oil.

Improved 50 and 100 yard 5 shot groups to 2 moa (over 3 times the CZ457 out of the box groups)

Then completely disassembled the rifle.

3) Polished bolt using JB bore past, Kroil and a Dremble
4) Polished Safety components by hand using JB & Kroil
5) Performed second bore lapping paying closer attention to hard spots
6) Replaced the crappy combination spring/ejector with a new factory part because could not locate an improved aftermarket item.
7) Adjusted the factory trigger to the lowest possible pull weight (don't have a trigger pull measuring device).

Reassembled after lubricating everything with Lucas Extreme gun oil and took the rifle to the range. Shot my first bullseye with the rifle after 7 fouling/zeroing shots. Rifle now shoots 0.75 moa 5 shot groups using both SK High Velocity and Semi auto at 50 yards.

Took a lot of head scratching, research, advise from a shade tree gunsmith (who had the bore scope), effort and some $. But the rifle now shoots like it should have from the box. The build quality, operation, design and accuracy still isn't even close to my CZ457 Varmint's out of the box condition.

Personally, I'll never buy another new Ruger product because my 10/22 bought about the same time is even worse. Ruger may have been good at one time, but the two I bought a couple years ago were atrocious. Rather than fixing bad Ruger products, I'd rather be spending $ on ammo and time at the range.

Glad you haven't. There are numerous who have. But adjusting the catch resolved the issue on mine. Some others have installed aftermarket magazine guides to solve the issue with 22lr's. Apparently the problemn is rare with the longer rounds, 17hmr and 22wmr.

Mine was an early one but it wasn't as bad as the OP's. It cerainly wasn't in the precision category though. it was easy to see that it didn't fit down in it's chassis correctly as there was quite a down angle from rear to front. The tab on the trigger assembly was too thick and wouldn't let the action contact the chassis. My mill made quick work of that problem but precision still wasn't there. Some lipstick on the bedding block showed no contact at all. It required a .010 shim on one side and .020 on the other to fix that. Better but still no seegar. The 15 round mag it came with was so sloppy it just flopped back and forth in the mag well and was never used. It's still brand new and stuck in a box of parts. I robbed one of my 10/22s for a 10 rounder and it was loose but not a rattly fit so I proceeded to shim it to where it fit with no slop but still dropped free. Now it was living up better to the precision part of it's name. Then the center blade in the trigger began to hang up and you might have to release and try again as many as three times to get a shot off. I tinkered and shimmed with no results what so ever until I finally just threw it in the trash can in disgust and installed a Timney. The extendable part of the stock also has some up and down movement that was annoying but a strip of clear plastic cut from a plastic jar fixed that. Now I have a rifle that pretty deserves the precision part of it's name.

At no time did I consider sending it back to Ruger. I felt if they let something out the door like it was to start with it it would just be a waste of time.

An aside: My son-in-law bought one in 17 HMR last year and it shot great right out of the box. Covid is behind us and it seems Ruger has gotten it's act back together,

Seems to be hit or miss on getting a good one. Mentioned Covid time frame in case that was the reason. My Trigger barely fits in the stock. The bolt design is inferior to CZ's. If mine wasn't so bad, I'd probably never known that CZ's were so good. The CZ wood stock models come both pillar and glass/epoxy bedded. I did replace the trigger on the CZ with a Timney because about once every 15 shots I'd pull one low and to the right. Suspected it was the Trigger, my new neighbor was a military marksman instructor, he

took one look at the 15 shot group and said "your right handed".

Well it wasn’t pretty!
Sighters were to a pasty on white paper. Easy to see hits.
Two on the pasty, good to go.
I thought.
Just could not readily pick out hits in the black 200yd small bore target even with 50X Leica scope.
10/22 mags kept jamming, I guess I lost count of shots.
Finally found one of 5 I had along that worked and finished.
Have to function test the mags now but I do have three new that I will use next week.
The Zeiss Riflescope and the Timney trigger are great but I don’t know about the Ruger.
It’s not the accuracy but the function problems.
Believe it or not we had a 10mph from the 220 degrees on the target

This weeks target @ 200 yds, almost a dead calm.
Did not touch a single setting on the Ruger/Zeiss other than clean the bolt, chamber and rifling.
first sighter low and left but next two hit the 2” target dot on white paper, we use for sight in.
Set the crosshair illumination
Image

just so I can see the center pip of the reticle against the black background on the ‘10’.
One 8!
Next week maybe two clicks to the right before sighters?
I know which way the wind is from a flag we use for each position and last week I distinctly remember from the left.
The Zeiss scope has excellent clarity, illumination and large knobs with easily readable adjustments.
The Timney trigger is superb, better than the KIDD 8oz I put on my Ruger 10/22 Competition.
Used one 10/22 mag that functioned.

Ruger has a 1” MOA guarantee at 50 yards with match ammo and an experienced shooter , not the best guarantee

Can you supply a reference to the Ruger 1” MOA guarantee?
That equates to a 1/2” accuracy at 50yds.

For 50’ Small Bore, the 10 ring is 0.22” so to shoot a ‘possible’ all you have to do is shoot 0.44” groups at 50’.
This equates to 2.64” at 100 yds.
Most Organizations now shoot 22lr at 50yds and indeed that are whole shooting disciplines built around 50yds.(ARA) (NRL?)
I think that at 200yds and beyond, It’s more of a calculational, wind drift type problem that more than negates intrinsic factory ammunition accuracy.
More important than accuracy is repeatability in the 22lr cartridge.
Which is why I shoot Tenex, Eley Semi-Auto Precision in my 10/22 and Lapua Super Long Range.

“Have and use both I’ll take the Kidd trigger any day.”

My KIDD is 8oz/8oz =1# for the 10/22. Timney makes two triggers for the 10/22, one at 2&3/4# and one 8oz/1#. Which do you have?
My Timney for the RPR is 8oz/1# but feels lighter than the KIDD trigger I have.
I realize that the triggers are not the same but the Timney on the RPR just feels better!

I bought a very early one. It was either made very late on Friday or very early on Monday by a hung over employee. I did a lot of work that Ruger should have and never did manage to get the trigger to work right. The center blade would hang up every third or fourth pull and resisted everything I did to eliminate the problem. I replaced it with a Timney and threw the factory one in the dumpster. It does about the same with CCI-SV as southerncomfort's picture shows including a flier in almost every group.. It is much better with RWS Target Rifle getting down into the .4's with no fliers but I am almost out of that ammo and it has been absent from shelves for a long time and I don't know if it is even made anymore. My sense of touch in my fingertips has deminished enough that I am leery of a trigger with less than a 1# pull weight and have adjusted two back up to that much.

What's a respectable 50 yard groups for a Ruger RPR?
Image

These are cherry picked 5 shot groups at 50 yards

Here's another 5shot group at 50 yards

I just recently broke the rifle down and made some free modifications to the rifle haven't shot it yet but I was just wondering what "stock" Ruger RPR's are capable of. I'm trying to get 1moa at a 100 yards, is that wish full thinking?
 
#27 ·
I haven't shot mine in quite sometime due to a physical problem. I had it down to less than .5" @ 50 yard groups regularly with RWS Target Rifle ammo. Mine is an early one and I had to finish a lot of Ruger's work for them before it would do that including tossing their trigger with the constantly hanging up center blade. A Timney trigger solved that problem.

If things continue as they are I will be back to shooting by midsummer and I'm looking forward to seeing just how rusty I have become with this rifle.

I sprung for a Shaw match barrel last month for mine. I wasnt gonna do this yet but found a deal I could not refuse.
MAN THIS BARREL IS GREAT!!!
Even before break in I have been shooting many groups in low .400's! Orig barrel averaged .7 ish. Not bad at all. Occasionally groups fell into the mid .500's.
