R55 benchmark vs cz452 varmint

[britguy]

BEEN HAVING LOTS OF ISSUES WITH MY NEW R55 DID A QUICK AMMO TEST AGAINST MY CZ

ammo used

federal 525 blue box 36gn hp
federal champion 40gn rn
winchester t22 target 40gn rn
rws match 40gn rn

(first time i've posted a pick so it seems a bit faint) right hand side top to bottom cz the rest r55 ,cz shoots anything well, best group was with rws match ammo $10 for 50 !!!

r55 best so called group also with rws.it will not feed hollowpoints,only roundnose with about 70% success with 2 mags.as you can see i may have to post r55 groups in shotgun forum!!

i think i may be testing the t/c lifetime warranty quite soon or if anyone wants to buy it pm me!!!

Maybe remove he barreled action from the stock, inspect for fit, and torque action screws to 25 inch pounds.

Shot three different ones and all can consistently keep 10 shots within a nickel at 25 yards and may shoot a dime with CCI Std velocity (and about the same with Fed Bulk and Fiochi Std velocity). One was helped by proper torquing of the screws.

First off, how clean were your rimfires. They do not shoot well from a clean bore.

Secondly, when changing ammo, run a dry patch through the bore between brands AND take 10 fouling shots with each brand BEFORE trying to make a group with it.

If you don't you will see very poor results.


When I change from 40gr solid points to Hollow points my groups will open almost an inch at 50 yards with a CZ452 Varmint.

But then a quick boresnake or dry patch and 20 foulers later, it will print a decent group with the hollowpoints.

test

I wouldn't consider 4 boxes of ammo much of a test to determine a brand my rifle will like, especially a semi auto. That gun should feed any type of rimfire ammo. If it were me I address that for sure. Then test after that. FS

My R55 Benchmark will shoot 10 round dimes at fifty meters using Remington Target ($30/500) if I really focus, nickels if I focus less, quarters require little effort. My 452 Varmint would do he same thing with less effort and Federal 525 bulk pack ammo. I've tried several types of ammo and the only feeding problems I've had with the Thompson were when firing standing and using the magazine as a hand rest; bad idea. The 452 was certainly a little more accurate and definitely a lot less ammo sensitive. Your results are not typical of these rifles from what I have seen in my own shooting and seen on the net.

didn't clean between ammo types, barrels were uncleaned
(about 400 rnds quick boresnake to start) as i know from past experience my cz likes dirt! this was meant as a comparative test with same conditions for both guns the point was to show that the cz takes things in its stride the r55 not. i've tried about a dozen different types of ammo,clean or dirty the r55 does not show any consistency. anyone recommend an ammo type that works well in theirs? i'll be buying a 10/22 soon if this continues as my marlin 795 shoots better and feeds anything and it was half the price!

Check action screws like lineofsight suggested. My stock was a bit loose on delivery.

My R55 loves cheap CCI Std Vel. Tight groups all day long. I give it a very light cleaning every few hundred rounds.

Is your scope defective (sloppy reticle)? I changed scopes to one with an adjustable objective and my groups tightened up more once the parallax issues were reduced.

i've had it apart a couple of times action screws are tight,it groups like this every time,been down the scope route,thought the bases might be the issue as the weavers i had on had a slight gap,swapped to t/c correct bases,replaced scope,these were the latest results.

My r55 likes cci minimags and eley sport, it took 500 rounds of minimags before it would cycle the slower ammo, groups are dime size at 50m with both types of ammo and not trying too hard. I wouldn't give up on it just yet.

Couple of things. 1) Yes the T/C base is the way to go. I had the same problem when originally the Weaver base was ordered. Never shot with it, the store that ordered the bases told me right off that it wasn't acceptable and ordered the T/C bases.

2) The other guys are trying to tell you to get a proper torque screwdriver and set it to 25 inch pounds. Not just "tight". The correct torque makes a difference.

3) Mine wasn't shooting properly until I used a torque screwdriver and followed the above. I kept getting strange fliers. My rifle was the one Lineofsight was referring to. Afterward it shot fantastically. We set up Lineofsight's little 22 Canadian tire metal target stand at 100 yards. No missing on the small triangles. Shotgun shells, no problem at 100 yards. The rifle shoots exceptionally.

CCI standard.

The end result. 1 moa at 100 yards with 5 round groups (no wind).

Give G96 a try for metal conditioning. Then use some oil on the high friction points such as where the bolt contacts the receiver etc. This should help limit failures to nothing. Plus cleaning is fast. You only have to wipe down the receiver. No scrubbing.

And if Epoxy7 can do that it really tells you how good the rifle is. Looks like it is another week of throw Epoxy7 in front of the bus

You mentioned you went the scope route / checked bases. By "replaced scope" do you mean you put the same scope back after swapping bases or did you try the CZ scope?

Went with the Weaver 411 bases while waiting for the T/C & Warne setup. The 411 had slightly smaller radius so only the edges touched but even with that setup no issues at all thus possibly your scope.

Again, try 24 inch or 2 feet pound on the action screws - if you dont have a torque wrench get the Wheeler FAT Wrench for $70 or so, useful on rings, bases, action screws... and also comes with proper bits (not tapered that tend to strip) well worth having in the kit.

Presumably you inspected rifling & crown and no issues?

Have you send an email to tca_customerservice@tcarms.com (Gail Lynch?), perhaps they have a suggestion.

ok then,have torqued action screws to 25 in/lb,the scope is a new vortex crossfire 4-12 40 ao (used the inaccuracy to justify that buy to the wife!!)put previous scope on cz and it works ok. going to try previous ammo and another few other types over the weekend,thanks for everyones input so far
to be continued..........

CCI standard. It's also a best buy for decent grade ammo. Not full out match grade but it's also nowhere near the cost either. This will give you an idea of what the rifle is really capable of. It's been shown to shoot extremely well out of 3 R55 rifles that I know of. So I pretty much consider it a known quantity with the R55. The other ammo choices may be hit/miss. Save yourself some time and grief. You can always go and try other stuff later. I did and guess what, right back to the CCI standard for this rifle.

As much as I like my Ruger 10/22 rifle, realistically the T/C is what the Ruger should have been. The Rotary mag and all the aftermarket parts have been the saving grace for the Ruger. T/C, steel receiver, match barrel screwed in not the Block garbage of the Ruger, and a last shot hold open. Great shooting semi out of the box. The trigger is a bit heavy but still beats the crap out of the stock and even the "target" trigger that the Ruger comes with.
