CZ 457

[AirGunShawn]

Martin, I would say its the last piece of the puzzle. I just happen to have the cash and wanted to know your question as well.
Better ammunition seems to play a much bigger role fore accuracy to me. I have 5 guns that I can clamp this unit onto and play with. The group above was shot without a tuner and reasonable with ammo.

 

[Mallison]

Is the American able to be customized
Or just the precision trainer and mtr

? What do you mean by customized ? By the factory, or ....?
I customized my 457 American by doing a Shilen select match ratchet rifled bbl for it - is this sort of thing what you're talking about?

Yeah, sorry, should have specified, how accurate are these for 50-100yds training
Do I need a custom barrel etc

 

[flatland1]

My American's factory bbl was a bit of a lemon - consistently shot 2 MOA 'groups' at 50yds with a variety of proven good lots of SK & Lapua ammo. I didn't want to screw around with making a warranty claim on it, so just ordered in the Shilen and replaced the factory bbl with that. The Varmint MTR OTOH, has shot pretty darned well from the beginning. It shot good enough with the factory bbl to use as a trainer or to compete in NRL22 matches. However, it wasn't as consistent as the custom bbls on my 40XB repeater and V-22s, so I've replaced the factory MTR bbl with another Shilen. Planning to do an extended comparison of these two Shilens to the Bartlein, Kriegers & Lilja bbls on my other repeaters over the summer months. I bought the Shilens because of their reputation in the .22RF BR world, and because they were available quickly. Time will tell how well they shoot compared to the cut-rifled Bartlein & Kriegers.

I see!
Thanks!
I'm not quite there for the moment...still don't know if a got good ammo and good barrel.
I'm working on it!

I love my 457 MTR. It shoots the CCI SV very well. I zeroed at 50 and took it immediately to 200 and 300 yards after shooting a ten shot group that was a little under .5 MOA. 200 yards was stupid easy with 7.4 Mils of drop with a light wind. 300 was a little more challenging when the wind picked up making hits on an 8" plate much harder. 14.2 Mils @ 300.

My 419 rail came loose somehow when I went to test Norma, Eley and Wolf. Of course the bolts are metric and I didn't have it in my tool bag at the range. I torqued them a little tighter and will go back to the range when i can to further test the rifle.

I changed the bolt knob after the first trip because the stock knob is too small for how hard the bolt close effort is. I was a little surprised how hard it was. Does everyone else notice this too?

 

[flatland1]

I made a bolt knob for my MTR that's fairly close in size to the 419 knob, and have been pretty pleased with how much easier it is t run the bolt on my rifle. I did put some NECO Moly Slide grease on the cocking ramp and thought that helped a little, on both the MTR & American. I kinda hated to put a big knob on the American's bolt handle, so have left the round knob on it for appearance sake.

Only with wolf ammo, which my MTR hates.

Do you have the stock plastic magazine release? DIP offers one that is all aluminum and is flush to the bottom of the mag.
It is only .07 or 08" longer but it helps

 

[BigTex]

It's the lightweight cheek that Manners offers on their compact stocks. Pretty straight forward install, if you're comfortable drilling 2 1/2" holes in a brand new CF Manners. It comes with 2 1/8" spacers and 1 1/4" spacer for a max height of 1/2". I have the 1/4" in it and its perfect.

I was contemplating having StockDoc do a full Loggerhead job, but I HATE sending stuff out for work. After speaking with Jim at Manners, I went with this option and did the install myself with a drill and a little MarineTex. I am in no way disappointed. It looked like it might have too much flex in the pictures online, but it is solid as a rock.

[BigTex]

It has been shooting 0.5-0.6 @50yds and 1.25-1.5" @100yds average with SK Rifle Match. I was hoping for better, so I bedded it with marinetex. We'll see today if it helps anything. I have some groups posted in the 6x5 thread.

 

[flatland1]

For any of you guys who've got a Precision Trainer and want better accuracy, I've got a 457 Varmint MTR (with the match chamber) take-off bbl after replacing mine with a Shilen select match ratchet rifled blank. I kept a loose track of how many rounds I fired through it, and it's under 500rds. I haven't threaded it, and it's still the stock 20.5" length. If there's any interest in something like this, and someone wanted it threaded, I can certainly dial it in and thread the muzzle. Not at all interested in cutting it back from the 20.5" length though.

Just fishing to see if there's enough interest in it to make it worthwhile to take the time to list it in the classifieds, and to give the 457 owners here a heads-up.

 

[Mallison]

if you were to buy a trainer, cz457 precision trainer or mtr
or would you go up to an mpa ba22?

Bedding made a huge difference. shooting pretty consistently in the .3s and .4s after bedding.

2. Vortex Viper HST 6-24x50mm 30mm tube + Warne rimfire 30mm rings, medium height (0.990''). Product code # 731M

731 30mm 7.3/22 Medium Rings -

All steel rings with a horizontally split design and only ?" wide. Assymetrical reversible side clamp fits a 3/8" or 11mm dovetail. Securely mounts to firearm with Torx style T-15 socket cap screws, 25 in/lb. of torque recommended.

warnescopemounts.com

The 50mm objective bell diameter is 2.26'' and almost touching the barrel with 0.045'' of clearance. Same thing with the bolt handle. The eye piece diameter is 1.745'' on the widest (zoom ring). This set up is 0.130'' higher than the previous one… so not exactly the perfect eye alignment with the scope… but this is the lowest I could put my Vortex on.

3. As you probably noticed, the bolt body of the new 457 slides in the receiver differently than the 455. As I saw on the previous pics that some posted here, we have to be carefull not going too wide with the ring clamps. Some rings won't prevent the bolt to slide properly. The width of the clamps of the 2 sets of rings I proposed here are pretty slim. I'm almost sure the new 457 bolt body/handle will clear these rings.
View attachment 7052268

This bodes well for me, I have a 457 Pro Varmit Pro SR coming, and the dovetail/ring height setup was new to me. I looked at the BScar rail hoping to use one of my many pic ring sets, but they were out of stock. So I grabbed a set of Warne 732M (highs) since they spec'd 50-56 fit. I have the rings now, they look really low compared to Pict rings lol. But from the looks or your setup with 731M's they should work fine with my 6-24x50. I may grab a set of 731M's to try as well depending on how cheek weld turns out, actually since they worked for you.

Tell me more about installing the Atlas Rail - I have several bipods but there all either Atlas's or Harris's with Larue pic mounts - so having a rail there instead of the two studs would be perfect .

You will see if the fit is too high for you... If you have a caliper, you could measure the clearance of your set-up (between the objective and the barrel) and if you measure 0.125" or more, the lower rings (731M) will fit 100% sure!

If you have 2 studs, you just need an Atlas rail and 2 10-32x3/4" screws. I only had one stud so I had to drill and install a T-nut in the barrel channel.

.071 with a Butler Creek. BC's are typically 2mm so if I did away with it that would jump me up to .149-ish which would work with M's. I'll wait and see how cheek weld looks. Right off the bat the stock seems short-ish, but that may be b/c I am used to running a PRS on a RPR 6.5.

 

[10ring1]

Just asking for a friend. Where, if any, can a 457 MTR be located? Anyone have any leads?

 

[billmeek]

Looks like the online dealers / distributors are currently out of stock.

 

[David Canann]

My local gun store is willing try and obtain an 457 for me. I am torn between the MTR and the Varmint AT-ONE and would like some help choosing.

I really like the idea of the Varmint AT-ONE as it has both the adjustable stock which I believe every modern rifle should have in some form or another as well as a threaded barrel. I am okay with either 16.5" stiffer or 24" to help keep bullets subsonic. I have no idea why CZ did not give this rifle a match chamber/barrel!

Because CZ only allowed the MTR to have the match barrel I maybe that would be the most accurate and therefore the most enjoyable. But with out being able to see this rifle in person I have no way to tell if I could get a good cheek wield. Also having read reports of accuracy from the MTR being similar to other 457 rifles and some people even replacing the barrel I am not so sure the "match" barrel is worth it.

 

[78Staff]

I thought about both the Precision Trainer and the AT-ONE models - in the end I was exchanging an RPRF so had to go with what the shop was able to easily get, and both of those were OOS/BackOrders. So I went with the Pro Varmint SR model. I'm a bit worried about LOP, seems shortish but might just be me getting used to it. Still hashing it all out with scope setup etc.

 

[flatland1]

David,
If you're referencing me replacing the factory bbl on my MTR, don't be mislead - I was being nit-picky because the MTR wasn't shooting as consistently as the custom bbls on three V-22s and a jelrod-converted 40XB with a Krieger that I'd done for it. FWIW, the MTR bbl had shot a couple of 10-shot groups at 210yds that were no more than a half-inch larger than what I usually see out of the custom repeaters. That's pretty salty for a factory rifle in my opinion. Since the 457's bbl is easy to remove from the action, a decent smith shouldn't charge an arm & a leg to thread one. I think the tight-chambered MTR bbl is worth the risk of finding out how well the stock fits you - I get a nice cheek weld on mine by using a BScar 25 MOA rail with Seekins .92" rings on an Athlon Cronus.

 

[David Canann]

Dennis,

So you would go with the MTR over any other 457's and over any other 22 bolt action that is not v-22 money?

Living in Utah I am surprised by how much people are willing to pay for the Vudoo and Desert tech firearms. May have to tour those facilities if they allow it.

Anyone know if it possible to obtain just a 457 barreled action? I do not see them on line. Would love to drop one in this:

LSS Gen2 Chassis

Our LSS Chassis converts your rifle to an external box magazine fed rifle, while improving accuracy, and giving the rifle superior ergonomics.

Would be a nice companion to my 6.5 MPA BA

 

[flatland1]

David,
That's kind of a loaded question. As much as I like the MTR's stock & tight-chambered bbl, I'm every bit as attracted to the precision trainer with the Manners PRS1 stock. It's a shame that CZ didn't make the same 20.5" MTR bbl available in the prec trainer, and to thread it too. But in my very limited experience, their factory bbls can and do vary quite a bit where accuracy's concerned. I believe I got a lemon when I picked up a 457 American, and so compared to that, my MTR is a hummer with the OEM bbl. So, if accuracy was the #1 most important thing to me, then I'd go with a MTR. AFAIK, CZ has never sold any of their .22RF rifles as bbl'd action, and I have no info to the contrary in the future.

I've heard glowing reports on accuracy from a few guys online that bought the precision trainer, but if you invested nearly a grand in one, I feel you'd have the right to expect very good accuracy. If you buy a 457, and find the accuracy to be unacceptable, I guess you could always contact CZ's customer service and see what they'd do for you. Or do what I did, and buy a custom bbl and fit it myself. Whatever - if your luck fails you, and you wind up in that situation, you'd probably wonder why you didn't just plunk down the price of admission for a V-22.

If the only thing about the MTR that you like over the AT-One I would go with the AT-One. A barrel change on the 457 is to easy. So if somehow it’s not shooting tight enough groups it wouldn’t be anything to rebarrel it.

 

[flatland1]

No question that bbl swapping on CZ 455s & 457s is easy - and if CZ starts selling MTR bbls as they do stainless American & Varmint bbls, buying direct from CZ isn't expensive. The big question in my mind is, if you weren't happy with the original bbl's accuracy, how do you know you're going to do any better with a factory replacement bbl? Best bet would be to go with an aftermarket semi-custom or have a gunsmith fit up a custom. Get the desired results the first time around, and you're gtg. If you hit a snag, then the question of going with a V-22 in the first place is even more valid.

ETA - I machined & chambered a Shilen ratchet rifled .851" straight blank for my MTR; did some shooting with it today at 50yds, even though it was pretty windy. It appears that the Shilen is enough of an improvement over the factory bbl to be worth the cost & effort, and that's saying quite a bit, since the factory MTR bbl was no slouch in the first place. If I didn't like the CZ457 Varmint MTR so much, I'd have just sold it and stuck with shooting my 40XB & V-22 repeaters. I saw improving the MTR as a challange, one made worthwhile by the quality of the new 457 action, trigger, and stock. Only more trigger time with it at 100-200+yds on a day with decent conditions will confirm the impression it made on me today.

Does anyone make an aftermarket chassis for the CZ457 action? (I was told by 2 manufacturers it has a different bolt pattern than the 455.) Got an MTR action I'm getting a Lilja bbl for and want a better chassis than the wood stock. (Stock and barrel already sold.)

Help ! Please !
