All you have to say is WOW on these new rim rifles, you thought the 452-455 where good >>> these rifles take it to a new Level!!

The CZ 457 in .22 LR cal. target model, a so-called ‘Match’ chamber has been used with dimensions on the tightest limit of allowable parameters. In combination with the other upgrades, this rifle guarantees 15 mm groups at a distance of 50 m!

Someone needs to stop listing sheit in the fugged up metric system.

0A length of 15 millimeters is the same as a length of 0.59 inches.

1.5" @50yds is doing real good using a 4x scope....

You are kidding - Right ??

If I had a 22 that shot 1.5" groups at 50 meters it would be gone in a heartbeat.

My standard for any of my 22 rifles, including my CZ 452 American, is a half-inch at 50 meters for 5 shot groups and certainly no more than 3/4 inch 10 shot groups.

CZ web page says nothing about a "Paragon."

Do you have a link?

Don't feed the cut 'n paste monkey bot.

Took me all of two minutes to find where "his" post originated.

Ha, ! I cannot help it.

Regarding the chamber. In certain hi-end models of the 457 the literature claims the chambers are cut to CIP spec. I mean all CZ are cut to CIP spec. That is not the same as a chamber that only accepts certain ammo, pushed in by hand one at a time and engraving the bullet into the rifling. There are a variety of "match" chambers used in the industry. Because the customers may use Remington ammo or worse and return the gun if the junkola ammo does not feed, CZ held the chamber to CIP spec. So what did CZ do you ask? In certain models, they ground the chamber reamers to minimum of the CIP spec. The closest min they feel they can hold in there manufacturing facility. Any way it sounds good to me, but this chamber is not like an Olympic rifle. Over at Rim Fire Central there are a lot of enthusiastic fans of CZ eager to try these new guns out.

The bad news is CZ no longer manufactures the old classic Brno based rimfire rifles like the 452 and 453. Well everything changes and these 457 are modern rifles with short bolt throw and 60degree (or so) lift. Designed for modern manufacturing. One popular feature is convention push to fire safety. I prefer a old school safety on the bolt. Like the M70 but CZ was backwards. The 457 safety is on the sear not the firing pin (bolt). The barrel slips in place on 457 rifles. The 455 had the same slip fit barrel and when the occasional lemon come along the owner can replace the barrel. I prefer a quality product where the barrel is rigidly attached and does not need to be replaced. I will miss the old guns. The 550 center fire has also been replaced with a 557. The magnum length 550 is till produced. The std 550 is gone. The 527 remains for now. I got two because I suspect only a matter of time before that line get "improved".

One by one the set triggers are being phased out. That reminds me the 457 rimfire is advertised to have a much improved and fully adjustable trigger. Not everything new is worse. The trigger sounds good. This should put an end to the practice by some to make unsafe modifications to the 452,453,455 triggers.

He's the newest guest of honor to my ignore list.

If I had a 22 that shot 1.5" groups at 50 meters it would be gone in a heartbeat>>> You try to put a 5 shot group into 1.5>>> I say you cant do it!! >> do it and then put up the picture!! and this we are talking about over the counter rifle!! Enjoy

A nice tuned not out of the box can put 5 shot group in a dime is good and that .5 Enjoy

Oh boy.......

CZ 452 American, only thing done to it is to adjust the trigger to a lighter pull, the bedding or barrel free-float has not been modified from the factory.

5-shot group at 50 yards from a Caldwell front rest and Protektor rear bag, ammo is SK Magazine. For reference the squares are one inch.

So yes, I can do it. Can you? I doubt it since your only skill appears to be as a poor linguist and typist with very little knowledge of what is and is not possible.

Ranting,

I don't say this to be demeaning in any way, but You need to learn to shoot. If you can not do better than 1.5 inches at 50 yards... a CZ 457 is not going to shoot any better for you.


A bench is OK to work on trigger control and sight alignment,

But after you iron out your trigger control and sight alignment===> get away from the bench and learn to shoot offhand, kneeling, sitting and prone.

After you learn to shoot a group as opposed to a pattern, try different ammunition in your .22 rifle.


I have had several Ruger 10-22's, most with a trigger pull heavier than the weight of the gun and I have not had one that would not do better than 1.5 inches at 50 yards. If one shot that bad there would be something drastically wrong ie. a bad barrel or chamber or?

There’s a reason his handle is ranting.

"He's" a bot. See the other thread "he" also started called, "Fading Fad" and put together all the nonsensical posts..

Drover-

You had nothing to prove but that is a nice target. When I first read his post I thought he'd made a typo. Obviously it wasn't. I'm glad I took your advice and got a 452. Your advice and pics have been great. Happy New Year my friend!!!

Take care,

Razorhog

Anyone know where I could pre order a 457 American? Been needing a 22 and I think this will fit the bill nicely.

Any good CZ dealers you guys prefer?

Correction, checked out it's profile and posts.. it has started a boatload of nonsensical posts and followups all over the 'Fire.

"He's" a bot. See the other thread "he" also started called, "Fading Fad" and put together all the nonsensical posts.. >> with 1,500 posts your not that smart!! Are You>> I have some swaMP Land >want to Buy??

As they say monkey do as monkey sees>> Some one Did >and does not like that I think the 17, is garbage so Im BAD!!>>Very Intro!!

You are an absolute moron.

You are an absolute moron.>>Not at All? Enjoy

Very intro>>>yes you are a moron>>?!! Enjoy

Happy New Year to you Razorhog.

Get out and enjoy that 452.

Hope you have a great year chasing hogs.

Not enough snow here so far this winter but still have deer every day, sheep a couple of times a week, and the elk are coming in at night this year. All the fence repair I did last spring was pretty much for naught since they have rode it down in a lot of places all ready. The place it is rode down worse is about 10 ft away from an open 12 gate but they choose to cross the fence rather than walk through the gate.

Well no idea about a CZ 457, but I do know what a 452 will do, 1.5" at fifty would be a VERY bad windy day. Dime size for 10 shots is about right when things are normal.

Don't know about all the BOT stuff, but I think a 457 is in my near future. Just fixing the safety is a great start.

Nice FYI Jerry. Nice to see one in a normal stock. Thanks!

Some of the new heavy barrel models look interesting.
I don't get "that CZ feeling" from the other models though.
They look like they're another company's rifle, designed to compete with CZ.....

reckon there'll be something left-handed show up sooner or later?

or just don't ask?

I see there is a lot of JIVE>>TURKEY >>TALK>>> anyone have one?? aNYONE SHOT ONE?

457 Paragon???

Mouthing Off I see >> but no shooting going on!!

Gotta say that the MTR looks good if youre into just benching small groups.... Assuming that the barrel quality is there consistently.

I have 1 model 455 (the short barrel version they started calling a Lux) and its an impressive shooting sporter.
I don't know if I got lucky or not but I have read online (FWIW) that when borescoped the 455 barrels have ranged from excellent to crappy.
I don't know anything about that, but I can say that using a slip fit barrel is really shouldn't be a downgrade accuracy-wise over threaded, and I'm a purist who wants a 452.
Why - modern manufacturing is especially good at making precision "rounds", both internally and externally.
And it's definitely less expensive than threading.
I wouldn't want to remove a barrel so the ability to swap is lost on me. I just don't see a problem with the new barrel mounting.

The front of my brain likes the changes, especially the 60° bolt.
The back of my brain doesn't want to see the old style go.

"Jive Turkey" ?! Really??

Now there's a term I haven't heard in years. Just how dark, I mean old of a boy are you??

As to the 457, I have two 452s and a 455 that shoot quite well but may have to complete the collection with a 457.

This is America........If God wanted us to be on the metric system he would have had 10 disciples......instead of 12.

Ranting , you could not hit a bull in the ass with a scoop shovel ....at 1 meter.

You will be on ignore ...before you can reply.

"This is America........If God wanted us to be on the metric system he would have had 10 disciples......instead of 12."

Wasn't that before King George?
