CZ 457

[WeeHooker]

WeeHooker - That is a nice looking MTR stock. In fact, the whole rifle looks pretty special, with that stainless bbl and custom bolt knob. If that's your rifle, and not the one that the stock came off of, post some photos of the groups it produces, please...

Thank you! Yes, this one is mine as assembled this week. It started as a 17hmr Synthetic American donor rifle 6 months back and has been evolving since. It spent most of it's days in a MTD Oryx chassis with this 22" match IBI barrel .The chassis was good but I realized that I just missed the MTR stock after selling that rifle to a friend in need. Hopefully, this is the last of its major transformations. ( OK, maybe a Timney trigger coming up) . I haven't shot it since restocking it but hope to get to it this week.

It's hard to catch the depth and contrast of the grain with the cell phone but it really is a nice piece of wood. I got lucky to have been offered it.

Anybody using a MDT scope rail on a CZ 457? Please post a picture, like to see how far it extends past the action.

I’m interested too. I’m currently set up okay, using the Area 419 rail, but I’ve got the rings maxed out forward to get decent eye placement and wouldn’t mind a tad more in that direction.

Fits perfectly IMHO. Sits a little lower than the A419 option. Those are low rings on there too,

Thanks, exactly what I wanted to see.

WeeHooker - Is that MTR stock just as you received it, or did you re-finish it? The finish on the butt looks a lot smoother and shows the wood's grain/figure a lot more clearly than most of the MTRs I've looked at, including my own. If it was re-finished, whomever did the work did a really nice job of it. It looks as if the letters that spell out CZ 457 MATCH TARGET RIFLE in the upper/rear part of the stippling on the forearm were stippled-over, which doesn't hurt the stock's appearance one little bit. Kudos to whoever did the work, or if I'm mistaken, and CZ decided to leave the letters spelling out the model of rifle out of the stippling on later rifles, then my complements to them. Any way you look at it, the stock sure complements the appearance of the rifle. Enjoy!

Well done sir!
I know they now sell the Xray back half, if I can get a Canadian shop to bring it in I might just swap out my MDT XRS setup.

I’ve asked this question on a cz Facebook group and 20 people responded. But not a single one answered my question.

Does the 457 need to be drilled/tapped to mount a picatinny rail that has screws that install through the top? I was looking at getting a BScar standard length 25 MOA rail but was unsure. I like the 419 rail, but $100 is a bit steep to me and I prefer the standard length look.

My 457 Pro-Varmint Suppressor Ready model has holes on the receiver, but they are shallow with no threads. Do I need a rail that has screws on the side like the 419?

 

[Appalachian]

Either rail will fit directly with the screws provided. I have both. The rails that have screws on the top don’t actually screw into the CZ’s rail. They just provide tension to level it and hold it in place.

Thanks. I genuinely appreciate the answer. I just wanted to be certain before buying.

I have the 15moa version of this rail and it A) fits perfectly, and B) stays tight and in place. Well made piece.

 

[flatland1]

I've purchased four of BScar's 25 MOA picatinny scope rails for my CZ457s, and have had excellent service out of the three that are currently mounted on: American, VPT, MTR rifles. Have used scopes as heavy as Athlon Cronus, which is a 34mm, 4.5-29x56 scope, with no issues.

I have both Rails, the 419 and the DIP 25 MOA. I like the DIP rail better because it about 1/8" + lower and is half the cost at $51 delivered. Both rails use screws to pinch the dovetail. The lower scope height the lower the cheek riser needs to be and is key feature in getting a good ER setup. I think the DIP rail is a better deal in terms of cost/ design/ longer. YMMV but check it out. https://www.diproductsinc.com/Detail.aspx?PROD=1422402 . The level on the 419 is nice but is not user friendly. Save the money and get a "Send it MV3 LRA" level. 30 MOA for the 419 vs 25MOA for the DIP rail. No drilling setup the Set screws is where the holes that you talked about contact. Call DIP and talk to their tech rep he knows the details if you still have questons. Also get a metal Mag well and extended Mag release with the Rail order and ditch the plastic Mag well. Its just the typical stuff you have to do to fix the cheap parts on a over prices production hardware, they are all alike no matter what brand that you have.

 

[mwiggi]

My LGS has one of DIP rails. Just wasn’t a fan of the extended picatinny rail. I like how the standard one looks.

I didn’t know they made a steel magazine release. I’ll definitely be ordering that. The plastic on the mag well doesn’t bother me right now but I think it probably would now that I have a bravo coming. Thanks for letting me know about those two options.

The Mag well parts are 6061 aluminum. So you like the Dovetail receiver look, so how high are you scope rings and what are to using for a cheer riser ? The extra pic rail length helps in getting the ER with longer scopes that are in the 10-50 X 60 range.

 

[mwiggi]

I’m using a set of warne 22 cal medium rings. Not a fan of the dovetail look either. Just didn’t know there was a standard length picatinny until I had my scope mounted and zeroed using the dovetail. Don’t have a need for a cheek riser with my current set up. But I did order a KRG Bravo and I’ll put a hoptic cheek rest on it, if I can find where I put it.

Planning on getting the bscar standard 25 MOA and a different set of warne rings to help me reach out to 300.

My scope is just a Vortex Diamondback tactical 4-16. I’d have to look to see where it’s mounted exactly on the receiver. I don’t have any plans to get a scope with that much magnification.

 

[phantasm]

I just finished setting up my CZ 457 and was wondering what you all are using for ammo? I picked up an assortment to run through it and see how it performs. Aside from the subsonic rounds, which I don't expect much out of as far as accuracy, does anyone have any experience with the SK and Eley? I've heard good things about it.

 

[Shoots 700's]

Center x, eley, and both sk’s should give really good results at 50. Need to see what holds up at distance.

 

[mwiggi]

I shot my best group, .2” using CCI SV at 50 yards, but there are a ton of flyers. I’ve had good luck with SK Rifle Match with consistent .3” groups, sometimes .4”

I use Norma Tac for practice at $4 a box and get less than a half inch groups. Don’t think I’d use it when I eventually start competing.

Whidden gunworks has a handful of different types of SK ammo in stock. Including rifle match and SK Standard plus at $78 a brick and $16 for shipping. Planning on grabbing a brick Friday to test out.

 

[gunjunkie45]

Sk Standard + shoots the best out of my MTR. CCI standard does quite well for less expensive, easier to find ammo.

 

[GimpyGolden]

All you have pictured are subsonic except for the Federal and SK LRM. I understand you are referring to the A/E and CCI Suppresor but thought you should know that match ammo is generally always subsonic.

 

[fredfish]

To anyone using dowels like I do to eject fired rounds or measurements for tuners. DO NOT forget to remove them before the next round. I did. I now have a stuck dowel and a fired bullet stuck at 5'' in barrel!!! I would have though the bullet would push out dowel, was I wrong. The barrel is at local gunsmith now, see what they can do.

I have the Varmint Precision Chassis MTR
From what I’ve tried so far, my rifle likes (in order):
Eley Tenex
SK Long Range Match
Eley Match
Norma Match
SK Rifle Match
Eley Force (practice ammo)

 

[Gassoline]

Lapua Pistol King shot as good (or better) as Center-X and Eley Tenex in my CZ457. I have a Lilja Tight bore barrel though.

I'm an IDIOT I had 2 bullets stuck. They had to burn the wood it was jammed in there. Good thing my second case didn't eject or maybe I would fire more rounds!! Remind self be ALERT to sounds.

 

[Norman1950]

Done tinkering on the gun for a bit. Swapped out the varmint 21" barrel for the varmint 16", put on an ATS tuner with my ODIN Works Navi suppressor. While I had the gun apart decided to get a Timney flat face trigger set to 7 oz. Thanks to AandJ Sporting for shipping out the trigger so fast. Also decided to get a new forend for the Indian Creek Design chassis to make to 15" barrel and tuner fit and added the Gray Ops external weights. Running the Arken Optics USA Info new EP5 scope with Burris XTR signature rings with Scars scope base.

Now just need to go shoot and tune the barrel with the tuner. The gun out shot me with the 21" barrel, but just wanted to check out the shorter barrel. Only thing I might change is a new aftermarket barrel way down the road.

Now the idiot behind the trigger needs to get more practice time for PRS/NRL so the gun can actually perform to its potential.

I use a dowel to push out unfired rounds from my Lilja barrel as well. I made a handle for the dowel from a champagne cork( fancy, I know). makes it easy to push and hard to forget. Had to use it this weekend.

SK Standard + shoots quite well through my Lilja, though it is edged out for consistency and grouping by SK Rifle match, especially past 50 yrds. I last bought my SK rifle match from Whidden gunworks. Very satisficed and I think the greater cost of the SK rifle match over the Standard + is worth it (to me at least)

First time out with the 457 chassis.

Suppressed with CCI SV possibly the most fun gun I have. Very satisfied with the accuracy with SV but it seems noticeably better with the Spectre than the Oculus. Left target is Spectre and right is Oculus, switched part way through to see if it was in my head or not.

 

[phantasm]

Managed to get out with my CZ 457 today. I shot 50 rounds of Federal Champion (40gr) and 30 rounds of CCI Suppressor (45gr) ammo. This was the first 70 rounds through the rifle. I'm pretty happy with it so far.

This shot group was from the Federal 40gr ammo. I'm rusty as hell when it comes to precision shooting but I'm happy with it.

 

[mwiggi]

Any of y’all swap to a higher set of rings? I had a set of Warne Steel low with BSCAR 25 MOA standard rail on my KRG Bravo. But I had to use the lowest setting on the cheek rest. Something felt off and couldn’t get comfortable behind the scope. Ordered a set of mediums and everything feels so much better.

I’ve always tried to get as close to the barrel without touching. The mediums with the BSCAR rail are less than a quarter inch from the barrel.

On another note, I broke a screw off in the base of the low Warne rings. Emailed warne and they are sending a brand new set. No questions asked and didn’t even want proof. They have a customer for life. This is my 4th set from them.

Could have more to do with the CCI SV. I’d try different ammo and see if that helps. Hoping my Mask doesn’t increase my group size.

Yep. For me, higher rings is usually more comfortable so that's what I go with. I've stopped worrying about how close the optic is to the barrel. I suppose that could help in some situations but the elevation adjustment needed is a known and can be compensated for easily.

I use my 'At-One' CZ457, 24" for benchrest (it worked out cheaper than a 2nd hand Anschutz), and have no real complaints.
But I feel the Boyd's stock is not the best for my use (well...I know it's not the best).
I'm thinking about a chassis, and not a lot of choice here in NZ.
For availability and price the Oryx chassis seems OK.
Any thoughts on the Oryx?
https://www.deltamike.co.nz/product/oryx-chassis-cz-457/
No use telling me get 'this' or get 'that' as we simply do not have much choice here, and US folks won't sell/send to NZ...so the Oryx is the one I'm looking at as being a 'maybe'.
I can get an MDT ACC system but at $1800+ (NZ) I don't think I will (it's a bugger being retired and poor).

I have an Oryx on my Howa in 223, and I like it well enough. The only experience with chassis's I have is this and my 457 in a KRG Bravo. I 3d printed some of the spacers from the oryx and got a vertical grip instead of the stock one. Only real complaint I have is not a whole lot of options for a rear bag rider. But I did see a Reddit post where a guy made a bag rider out of a 6" x 6" metal bracket that I'm going to try out.

 

[Grey Kiwi]

Thanks @Voluble...I did a quick google and found this...
https://www.jamerllc.com/products-1/jamer-bag-rider-for-the-oryx-mdt-chassis
So that is on my list now.
Something I never thought of. Much appreciate the idea. I could make my own from steel, but I can't be bothered 'making' stuff now. I'm getting lazy/tired in my old(er) age.

 

[gkgeiger]

Well, I just picked up my second MTR. I sold one last year and bought a VPT with 24” barrel. It has been a good rifle but I wanted to try the MTR again. I’m going to mount my 45X45 scope and a Bscar trigger. I’m moving to Florida in a month and will be looking for places to shoot.

 

[Grey Kiwi]

Is the XLR Industries Element available there?

Only for the bigger stuff (Rem 700, etc). One supplier only. Nothing for CZ457.
Prices range from $1299 -$1749 (so I probably won't go there!).

Yeah. Shame that SCSA haven’t gone there yet. I have seen a Howa .22 long rifle, fitted with a TSP stock, as opposed to the standard plastic stock which influenced me to buy a Ruger .22 WMR bolt-action instead of the Howa equivalent. Jaco, who is NZ Outdoors’ Howa brand ambassador, brought the Howa rifle along to a product presentation at our Branch Range. I never got around to shooting it though, as I was too busy playing with Mauser (I like the M12 but not the M18, which is still vastly superior to the ‘bottom of the barrel’ U.S. economy rifles) Sauer, Blaser, Lithgow, etc. having a gossip and eating some nice hot tasty snags.

We can but wait and hope. I was a TF Engineer myself, as opposed to a gunner but we did share our camp with 22D battery for a while. We never mentioned the extra flames on our ‘flaming grenade’, much.

 

[Grey Kiwi]

We never mentioned the extra flames on our ‘flaming grenade’, much.

Yeah, 9 flames...instead of the obviously superior 7 flames!
I'm sure that some readers are bemused (?)...so here is the said article (a lapel badge, NZ Artillery).
Never figured Engineers and grenades. Although you guys blew up stuff too.
My old Dad was 8th Army Engineer (Tobruk, El Alamein, etc)...he had a lot of fun blowing up stuff!
Anyway, I have ordered the Oryx chassis and it arrives this coming week. Then I'll sell the Boyds 'At-One' stock as it won't be used again.
I'm only using my CZ457 for benchrest, and have other .22's for hunting.

Anybody know what the factory 16.5” barrel weighs? Debating on getting the proof cf 16.1” barrel at 22oz

[Rowdy99]

I am having problems with a CZ 457 MTR not extracting rounds after they have been fired. I am shooting SK Standard. When the bolt and extractors are clean it won't extract probably 1 in every 30 rounds and then after bout 100-150 rounds it speeds up to 1 in every 10 rounds not being extracted. Has a bartlein barrel on it

What are the solutions to this? New extractors? Polish up the chamber? Need to take it to a reamer?

Any input and advice is greatly appreciated. Thanks guys

 

[mikeshaw2]

All righty then! I've decided my BMR isn't quite the right tool for the job for PRS style matches.

I've got a line on a 457 in an at-one stock for a decent price.

What am I getting that's different than a BMR? I know about the adjustable stock, but the rest?
