Your rifle was clamped in a vise and three shots racked off as quickly as possible - next please. No sighting between shots (many CZ rifles don't come with sights). It's a function test only.
It's your job to extract the accuracy.

Was it supposed to say that "precision is not the only aspect" of deciding which one you shoot? If so, I agree.

When I worked in a gun store, I sold dozens of CZs. We learned to pretty much ignore the test targets. Some of the very best groups came out of rifles with the most awful test targets.

For function, there is no reason to print out a paper with measured groups.

Talk is easy, what are your sources? It is 5 shots not 3. There is no reason to sight in to shoot 5 shots. How fast? Really! What is that about? I have seen many cases where shooting problems discussed on RFC correlated very well to the test targets. Specifically, these targets were posted for 457 rifles with vertical stringing.

Obviously, I mean, mega obvious, an experienced rim fire shooter should be able to better a test target. Unless it was a total fluke. Now, one group of 5 is no way a through test of any firearm. I grant that. But; they are far far more than functional only test. It is a classy extra step that few manufacturers will take. I would not dismiss this. It is IMHO a good thing.

I am also going to guess, because I dont post more than I know, that if the test group was bad enough, the gun would not get boxed up and shipped out. That for a gun that functioned 100% and did not shoot for beans.

At one time they fired 5 shots, but now it is only 3. Since no sights have been ever put on the gun in the box I am looking at, I would have to suspect it was clamped in a vise and fired. It seems to have worked pretty well.

“Ammunition mgf: 22LR, RWS, 40 grs
Range of fire: 50 m
Number of impact: 3
Dispersion area: 2mm
Coord’s of mean point: -5mm;1mm“

Looking at the test target, there are 2 shots in one hole and one shot overlapping and 2 mm (.07) higher directly vertical. The shots are 5mm to left of center, and 1 mm high.
Good gun to buy?
CZ 457 American.

Well, I guess there is no rhyme or reason to the number of shots fired. I know it used to be 5, and was 5 on October 11, 2019, when the OPís was fired.
The rifle I am looking at was fired in August, 2019, and they only fired 3.
Very unusual?

Yes, that was the intention. My original post has been edited to include "not". Thanks for spotting my omission.

For another data point, my At-One was tested on August 2, 2019, and five shots were fired.

Assuming if it’s shot is a factory ideal condition using top grade ammo and it resulted in greater than moa pattern ... and this is an mtr, should it even have been shipped out for sale?
Any comments / advice appreciated.

Best,

This is a perfect example of unrealistic forum expectations meeting reality. I've tried to shoot once a month for the last forty years at a very busy range. .0325 groups @ 50 yards represent about 1% of what I've seen from hundreds of rimfires over the years. Hang out at BR matches where everybody has $3K bench whales and YMMV. MHO

MOA is a fine factory rifle at CZ prices.

Good observation. I know my expectations are unrealistic. My problem arises from the fact that my first 22 was pre letter Winchester 52 given to me by my Grandfather. My second 22 was a Marlin 39a, and my third was a CZ 452 that just happened to shoot 3/8 to 1/2Ē groups at 50 yards. My last 22 was a cooper 57M that shoots like the Winchester 52.
I will be getting a CZ 457 for Christmas. It will have to meet high expectations. I have steeled my self all ready as to what to expect. As a result, I all ready know I will do a trigger job. I all ready know it will have great ammo and a great scope to give it a chance. But in reality, it might end up a ďproject gunĒ and if that fails it will move on. Yes, I have (possibly) unfair expectations.
To get somewhat back on topic, even though I donít give much credence to the test targets, this one is impressive with a 2mm spread, and 2 in the same hole.

Ok guys. You are right. The mtr has proven that my concerns with the hit pattern chart were misplaced.

I took it to the range today and fed it an assortment of sk ammo and aguila rifle match and it seemed to do fine with everything. But in particular it worked well with Sk standard plus and biathlon.

Not much wind but frozen fingers don’t help.
On sand bags and a block. The following pictures are some Sk standard plus and biathlon.
all are 5 shot groups.



Thanks all for comments and helping me to cool it before you shoot it!
