Ruger Precision Rimfire - My Final Thoughts

[Peter988]

Target rifles very likely have match chambers, most .22LR rifles have sporting chamber spec.

Blade racer - can you expand on that for this dummy please. How do they differ?

22LR Match Chamber Dimensions.JPG (85.34 KiB) Viewed 6938 times

A Sporting chamber is .2307" diameter at the face tapering to .227", Match is .227" at the face tapering to .2248".
A Sporting chamber is a .818" long taper, Match is a .643" taper.
A Sporting chamber has the lead at .8751", Match is at .6876".

Match chambers jam the bullet into the lead, which is why they generally shouldn't use CCI Stinger length cases.

bladeracer, thanks, I've been looking for those technical specs since I first saw the warning on a box of CCI Stingers that they shouldn't be used in match chambers.


With regard to tuners, I have a Starik tuner and 30cm sight base extension tube on my rifle, the tuner is very cool and has a weight that can be adjusted forward and back along the tube but is optimised at the factory for my barrel length.
The idea is that the weight changes the resonant frequency of the minute whip effect along the barrel and is tuned so that the bullet exits the barrel on an upward movement of the muzzle, a faster bullet will get to the muzzle sooner than a slower bullet so will be released at a lower angle, hence both bullets should have the same height at the target even with a 30 fps difference in velocity.
The tuner only works with vertical stringing of groups due to ammunition variations and groups from my rifle do seem better with it than without, only by a couple of mm at 50m though, it may even be the extra sight radius that's helping the most but I like it.

I think you'd have to be pretty dedicated to very tiny groups to throw another $600 at your $800 hunting rifle, but it'd be an interesting toy to experiment with. For a beginner it might be of more benefit overall to spend that on a case of ammo and 5000rds of practice.

OK thanks.

I threw $600 (and more on other parts) at my $9,000 Olympic grade target rifle because that extra 0.1 score per shot matters to me, ammo costs are around $2,000 per year, this is an expensive hobby.
You have to be seriously into target shooting before a tuner is worthwhile though.

What action did you use in your $9,000 competition rimfire?

[rc42]

Bolt action?

It's a Walther KK500 so it comes from the factory in Germany with everything ready to go.
Awesome rifle, a lot of people refer to their rifle as a 'tack driver' but this one really is, it's far more accurate and consistent that I will ever be.

[SCJ429]

Walther, I thought you might have a Bleiker if you spent $9,000.

Lovely rifle that KK Walther. You will do well with it.

I use a tuner on a piece of junk CZ to help me shoot at 200. Cheap way to tune a rimfire.

[rc42]

The current pricing on KK500 rifles is around $8.500 to $10,500 depending on options, the Bleiker is a little more and the Grunig & Elmiger a little more again, those latter two are over engineered with more to go wrong and less able to cope with a bit of dirt so I was less keen on them, I do like the stainless barrels on the G&Es though.

The Anschutz models are generally cheaper than the Walther but lack a little in the trigger feel and don't have the short bolt and loading port positioned so you don't have to lift your right elbow, they are a few years behind in technology and design but all are superbly accurate and still far better than I'll ever be.

It takes a long time to get all of the possible stock adjustments to the best position but once done these rifles fit like no sport rifle ever could and are a pleasure to use shot after shot, even as your hand goes numb from the sling.

[SCJ429]

For a while there the Swiss Bleiker rifles using US Lilja barrels were the things to beat in 3P competition. Not that the Walther has not had its share of success.

I was very impressed watching Matt Emmons shooting his Anschutz in a Precise stock and it didn't hold him back. Years ago I used a Anschutz 1813 and I still like the walnut stock. I think it is time for me to buy another one, keeping my eye out.

[rc42]

I believe that sponsorship plays a larger part in which rifles the top shooters (I struggle to call them athletes) use than the accuracy/consistency of the rifles themselves.
Olympic and World Championship finals are dominated by Beliker, Walther, Grunig with occasional appearances by Feinwerkbau and Anschutz (although a surprising number use the Anschutz Precise or G&E stock with Bleiker actions).

For club use they all look pretty but really aren't worth the cost just for improved results which they may not even deliver if the shooter isn't up to it. A top of the line rifle really is more enjoyable to shoot though.

There are a couple of Walther KK300 Blacktec rifles at my club, and a couple of the older Feinwerbau 2700 models, there's even a couple of Anschutz rifles but their model numbering system is still a mystery to me. They all consistently out shoot my KK500 or more accurately, they all out shoot me, I know it's not the rifle's fault and I'm getting better with time.

How many 22lr firearms have you bought mate. I thought the rpr was your only rifle... anything nice and juicy in your collection yet.

For anyone considering the Ruger Precision Rimfire for down the track

The Federal F510 does agree well with my Ruger Precision Rimfire also

However, CCI Standard is still more consistent overall

But for plinking fun

The Federal F510 is a great round I found
Even cheaper than CCI (and with decent results)
