CZ 457

#1,801
The only differences I've seen in the several 457 rifles I've bought was that the latest VPT had a trigger shoe that's matte black instead of shiny silver like the others (2 Americans, Varmint, Varmint MTR) I've got. I seriously doubt there's any differences other than that in the 457 actions, no matter what model you buy. If I were buying one just for the action, I'd get the Scout, as it's the least expensive model I've seen listed. BTW, I've re-barreled two of mine - an American that really didn't shoot worth a hoot, and a Varmint MTR just because I wanted to compare the OEM bbl with its 'match' chamber to a Shilen select match ratchet rifled blank that I chambered with a PTG EPS reamer. The improvement in the American's accuracy was huge, and there was quite a bit of improvement in the MTR's accuracy as well, even if it wasn't nearly as noticeable because the OEM bbl wasn't bad at all - at least, not compared to the American's factory tomato stake.

So I’ve got almost 750 rounds down the barrel now. After 500, she really tightened up!! Here’s a 50 shot group at 275 yards this morning with a 6 mph head/cross wind. The first shot, that is way right, was my first guess at the wind. This is a 7x8” steel target for size reference.

Welcome to my world…I contacted Cz and was told they have no idea when they’re going to restock. I think I’ve looked everywhere imaginable. I did happen to come across a 455 extractor but wasn’t sure if it would work in the 457. Looks the same but you never know.

Good luck

I contacted CZ a few months ago wanting to buy an extractor and spring. They said they would send them under warranty, but they were out of stock. They sent me a spring, but I'm still waiting on the extractor.

I've read some pretty negative posts concerning Lilja's barrels here over the past several months. My experience with Lilja 22RF barrels is limited to one titebore blank I ordered from them for a CMP Rem 40XB that I had Jonathan Elrod at Modacam Rifles convert to a repeater using V-22 mags back in 2015. I ordered the blank in Rem sendero contour to finish at 26" - my thinking at the time was to keep the finished rifle as close as possible to my CF PRS rifles. I did the fitting & chambering on it, and also did a Krieger blank in the same contour, but finished at 22" at about the same time. I've shot this rifle more with the Krieger barrel than with the Lilja, but have enough experience with both to make a valid comparison. The Krieger is a hammer, comparing favorably with Bartlein & Kriegers on a couple of my Gen 1 V-22 repeaters - but the Lilja consistently shoots groups just a bit tighter.

Since then, I've fitted & chambered barrel blanks from Bartlein, Benchmark, several more Kriegers, and several Shilen select match ratchet rifled blanks for a couple of Gen 1 V-22s, one Gen 3 V-22S, and several CZ 455/457s. That single Lilja is still somewhat of a standout where accuracy's concerned, and may be the single most accurate barrel I've done for a repeater. The only thing I've noticed is that it likes to be cleaned every 120 or so rounds to maintain its best accuracy, but all I'm doing is a couple of wet patches (using Ed's Red), followed by a couple of dry patches.

Note that I have no experience with any of the pre-fit Liljas, and the Shilens I've done for the CZs were all glue-ins, allowing me to omit the cuts for the grub screws their OEM barrels have. Aside from a JGS Nevius reamer I used on a Shilen for my V-22S, all the other barrels were chambered with a PTG EPS reamer. I have no idea what reamer(s) Lilja uses on their pre-fits for bolt rifles. Certainly not a definitive study in typical quality of Lilja barrels, but I wanted to throw that out there for anyone considering buying one for a CZ455/457.

With Lilja it is true about the tenon diameter. With the barrel Lilja provides a set of five shims, .001 - .005., which allows you to set the headspace. I recently got one of their barrels for my 457. I set the headspace at .043. I took it out yesterday for the first time and put 75 rounds through the barrel. I really can't speak to the accuracy because of my skill level.

I put a Lilja prefit varmint contour in my 457 and couldn't have been happier. CenterX is a consistent performer at <.5in groups at 50yd. SK Std+ also does very well just has a flier every couple of groups. Fed Automatch also does well for plinking and higher volume shooting.

I can't remember what I set my headspace at. .043 or .042 sounds about right from what I can remember though. At one point I was going to play around with headspace and see what gave me the best accuracy. However I've been satisfied with the accuracy (and a bit lazy) so I haven't tried tested it.

I've been pleased enough with the factory triggers on my 457s after getting them adjusted down to a pound or just over to leave them alone. But after shooting my V-22S BR/F-class rifle with the Flavio Fare trigger set at a couple of ounces, I can see why someone might be wanting a lighter trigger for their CZ 457. If I were going to invest in changing out one of mine, I'd go with BScar's 2-stage trigger.

I'm waiting for a flat version of the Timney. With the YoDave spring (and BScar's trigger pin with E-clips), I've reduced my pull to around 9oz with minimal over- and pretravel. This is good enough for now, since what I really want is the flat shoe.

keep us in the loop. I'm on the Bscar trigger wait list. I'm in no hurry with a similar set up as yours.

BTW - I installed a Kidd trigger on a 10/22 I got for Appleseed this summer...man, that trigger is heaven. I had no idea it would be that good. I had to work hard to avoid the temptation of buying a complete Kidd rifle after all I put into that 10/22...should have got the Kidd rifle in the first place. - typical lesson repeated many times with my gun gear purchases in general.

Before installing it, I had tested the trigger weight when I first got it. From the Factory the pull weight was 2 lbs 3 oz. It felt a little heavy but not too bad. Installing the spring took less than ten minutes (pull weight now 1 lbs. 3oz just by installing it). It feels 100% better, smoother and light.
With that said, I did get the Timney CZ 457 trigger. Is it worth it? I guess that's an individuals answer. I myself am glad I got it. Simple installation and i have it down to 8 oz. with zero creep. Really like the curve (less then the CZ). The pull is very nice and breaks like glass.
Could I have done that with the CZ trigger - most likely. I got mine directly from Timney with a discount for being a veteran.

Got out to test some SK Match, Long Range Match, Lapua Center-X and Midas +. The Long Range ended up being the obvious winner, with Midas + as the runner up. The Match was a mess and the Center-X was similar to my SK standard results.

this thread is going to be some long reading, I just picked up my CZ 457 At-One (16.5”), this afternoon. I already have the iron sights for my shooting league, hopefully will get a chance t take it to the range, early tomorrow morning.

The Timney is worth it. Its not like the 457 factory trigger is horrible, it isn't. With the Yo Dave spring mine averaged around 12ozs. I say averaged because when I tested it recently I discovered it will break anywhere from 11 to 13ozs. Playing with it on a bench, it feels fine.

But there is a definite step up in the Timney. More crisp, more consistent. A half dozen tests on the trigger gauge gave me 11ozs every time. The quality of the components is better than the factory trigger. It is a better quality of manufacturing. Given the fact that I compete with this rifle out in the elements and the dirt, combined with the high usage, the Timney is absolutely worth it.

Got this in a trade. First CZ. Paint was horrible so I threw some left over stencils on it right over the Manners sponge. This was the unthreaded version, so we had to fix that.

Got scope and rings, just haven’t got around to mounting it.

Shot mine for the first time today, I’m not impressed. The CZ part is very good, the Boyd part is pure junk. It’s like shooting a 2x4 with a barrel attached. It’s extremely heavy, rougher than a Cobb, two slivers in my fingers already, balance is terrible. The adjustable cheek piece and butt plate, need a pry bar to move, the adjustment buttons barely move. its akin to 7th grade wood shop project, that got a C-. The CZ part is a solid 9 on the 1-10 scale, the stock is a solid 2, on a whole the complete rifle is somewhere between a 5 and a 6. A gun show purchase, you live and you learn. Probably either a candidate for a new stock or life as a safe queen.

I was playing with some SK Rifle Match and Wolf Target Match today at 100 yards with the CZ457 VPT. Range conditions weren’t horrible but the wind was consistent. @ 100yds had to dial .6 mils. For the first target I uploaded I would have to hold an additional .1-.2 mils depending on the gusts. The wind died down for the second which showed a little better result. That said, this rifle shoots like a dream and loves both types of match ammo. Dope was consistent between the two manufacturers. I was only able to shoot two 10 shot groups at 100yds and had to leave, but thought I would share none the less. Shot off of a bipod and rear bag.

Can't wait for the availability of match ammo to come back.

Don’t mind my thumb, I had a misplaced and unwanted 30cal hole on my target so I covered it up.

Does anyone else here have issues with the Anarchy Outdoors 10 round mag extensions? Both of my mags keep jamming up when loaded past 10 rounds. I still leave them installed just for ease to hold onto for reloads, but would be cool to get them working properly.
