CZ455 Varmint vs CZ457 AT-One 

Hi Tyler! Appreciate you making this video, it's well done! I upgraded all of my older CZ .22lr rifles to the 457 after picking up a CZ American 457 .17 HMR and finding that for me, it was the perfect action and over-all rifle design. I field shoot and informally target shoot year round, to keep in shape and good form and these rifles are great for that. My most used 22 rifle is a CZ Royal that I equipped with a Vortex Tactical 4-12x scope on a Area 419 30moa rail. I shoot CCI Velocitors in it for field and long distance, but it will shoot like a target rifle when I switch to target grade ammo! It's one of the most accurate sporter 22 rifles that I have seen and does give my MTR a run using the right ammo! That MTR shoots an average group of .719 at 100 yards, so the Royal is earning its keep. I have a CZ Trainer that I'm glad I picked up, since CZ isn't making this basic model now in 2022. I leave it open sighted for old times sake... It is another very accurate rifle. The American in 17 HMR will often put three shots well inside a dime at 100 yards, and generally shoots extremely well for a sporter. There are a lot of real good 22 rifles around these days that shoot very well. I like CZ because they are an all around great, traditional style rifle and they provide reliable, accurate service.

There have been tests of the effects of barrel length on accuracy using 1000s of rounds with different ammo. 16 inch and 24 inch barrels were compared on the same gun. The result was that the longer barrel provided more consistent accuracy, at the price of about 50 fps in muzzle velocity. Generally testers do a poor job of explaining this, but from a physics perspective, I am shocked no one mentions the effect of rifling. Bullets don’t immediately assume the rotation rate of the rifling, but rather “spin up” to the rifling in the bore. This takes time and a longer barrel allows more energy to be transfered into bullet rotation which is key to in-flight stability. The barrels on the 455 and 457 are, as far as I know, interchangeable, and since you are using a sled, the main difference in the two guns isn’t the cosmetics of the stock, but barrel length. To me, it appears the 457 created more tight groups, and I suspect this is strictly due to its longer barrel.

Can’t have to many CZ .22s!

I guess what worries me is that first shot being a flyer. I wouldnt like that for a rifle im gonna hunt with..

I appreciate that you provided a time link to each rifle's "wrap up".

I like the looks of the 455, it's more traditional.

I’ll stick with my 455 Varmint even though the 457 has some nice upgrades, you just can’t beat the classic look of the 455.

Once again, looks like everybody's CZ's do the same as mine...first shot, cold bore is a whoop de doo, could be anywhere. I've had them go as far off as 6 inches. Once that first shot is gone, it's right on to tackdriving.

Would be nice if you stated which target you wear shooting at next

I have the 457 Varmint and it shoots very well. Wolf and SK standard work well in mine.

Apples and oranges. Cz455 at-one v’s cz457 at-one is a true comparison.

That's crazy accurate! What scope, and what power?

have you noticed if the at one with longer barrel is quieter than the 455? some say longer barrel .22lr rifle will be quieter than the shorter barrel.

Nice video , what bipod are you using on the 455 please?

Problem with this platform is constant lack of magazine availability for CZ 452/455/457 rifles. This issue has been ongoing for years. When they are in stock, they can be $50 plus. Guys have been paying $70-$100 each, so a handful of mags can cost more than the rifle. Get it together, CZ.

The top one is the 455? That's the one I like cause it looks more conventional, that said, I'd.keep them both. Don't get rid of either, just add more.

Holee crap i can't believe how many small groups those things are shooting with so varied a bunch of ammo. And shot right over the previous groups too. I been told you have to shoot at least 5 of a new brand before you shoot for groups. Very good outing there. I have three C Zeds meself but they are more finicky.

Take 5 Practice Shots To Heat Up The Barrel, Then Shoot Ur Groups, For Best Results...

New to CZ 457 MTR varmit. Love so far .just wish mine was threaded barrel

You ever tried cci stingers? Ive had good luck with them

I liked the 455

What is the tripod on the 457? Is it stud mounted or something else or m-lock?

What’s with ELI ?

The 457 is cheaper to produce. That's the difference. Have 3 455s and one 457.

What does at 1 mean. It makes no sense

50yds that's disappointing

😁😁😁👍👍👍verygood

.22's Are For 50yds & Less, .17 HMR Are For 50yds To 100yds...

Pretty much meaningless "test".

CZ 453 is still better. Also it is CZ, not CZEE. No ee's on the name!

You should learn to shoot without that lead sled.
