The difference is the chamber and only the chamber. The MTR, theoretically, should be more accurate. In reality, though, some standard barrels shoot as good as or better than some MTR barrels. You pay your money and take your chances.

 

I bought a Varmint for the wood, and debated picking up an MTR to go with it.

During my research on the MTR, I could swear that I read somewhere that the MTR barrels (all varieties, not just Varmint MTR) were hydraulically lapped. I took my Teslong bore scope to the LGS and they let me scope 2 MTRs. Both appeared to have a near mirror polish.

 

Do some research here in the forums. It seems that question is asked weekly. Answer is always just as Barrelhorses states.

 

My 1st CZ457 Varmint MTR was purchased preowned but was sanctioned ARA factory class winner with RWS R50 straight out of the box with only a scope mounted to it. My 2nd VMTR was purchased brand new several months later and is equally as accurate so imho the odds of getting a very accurate mtr barrel are very good. Good luck and happy shooting.

 

I'll chime in also; I have both a CZ 457 MTR 20" heavy barrel and a CZ 455 VPT 20" heavy non-match chamber. the older 455 is way more accurate and a LOT less picky on ammo. It's a barrel lottery my friend!

 

I may be wrong, but I believe the MTR barrels are made in the US, the "Varmint" barrels are made in europe. North American Barrels are SAAMI Standard; European Barrels are C.I.P. So, what does this mean?
SAAMI Sporting standard is considerably looser than the SAAMI Match Chamber.
SAAMI Match Chamber is virtually identical to European C.I.P Chamber.

So, all CZ Barrels made in the Czech republic must conform to C.I.P standards are therefore "Match Chambers" by definition. All barrels made in North america, must comply to SAAMI Sporting chamber unless marked "Match Chamber"; I don't think that MTR has to actually comply. MTR means "Mountain Tactical Rifle"

You are wrong.

CZ makes its rimfire barrels in the Czech Republic. All CZ .22LR barrels conform to CIP specs.

CIP specs for chambers show the smallest dimensions allowed by regulations. Some chambers may be larger than others. CZ doesn't specify the precise chamber dimensions found on various models.

It is reasonable to suspect, however, that the chambers on the semi-auto models are a little bigger than those on bolt actions. With the bolt actions is is reasonable to suspect that the MTR (which stands for Match Target Rifle, not Mountain Tactical Rifle) and other models with the "CZ match chamber" have somewhat smaller chambers than other bolt action .22LR CZ models.

 

Thanks' Guys, I am in the process of buying a MTR barrel, I was just wondering what the extra $140 was buying me. More accuracy, I HOPE.

 

 

I had to ask about hydraulic lapping when I first read the CZ advertising.
The neoprene plug is pumped back and forth in the bore a set timeframe.
No method to ensure that the soft neoprene surfaces the bore
in the same way that a lead lap that is formed to fit the bore
and applied in a manner that a skilled technician can.
That was one of the reasons given that true match barrels cost more.
Hand lapping is an art. Hydraulic lapping is a basic mechanical process.

 

Going back to the original question, I built my chassis MTR by starting with a Scout, and probably saved tens of dollars doing so. It shoots great with the 20" Varmint barrel, but I recently got the MTR barrel. Once installed, I'll get to find out if it shoots better, or is just more fussy about ammo like my last two match chamber barrels were.

 

Actually good to know that a MTR barrel is $319. Most aftermarket barrels are $450+

That cost Is probably to keep people from buying varmints or cheaper and simply barrel swapping.

 

If CZ barrels were hand lapped, that information would be identified. It costs more to hand lap a barrel than to do something mechanically. For more details, see posts #9 and #12 here (212) Are CZ Barrels hand lapped??? | Rimfire Central Firearm Forum

 

I have the CZ 457 Varmint and my shooting buddy has the MTR. We have shot each other's rifle and have concluded that they are approximately equals, depends on the day and the ammo.

 

If you are only going to be shooting from 100 yards on in, I would probably get the Varmint model. If going for longer distances, get the MTR as it has a match chamber.

But, also keep in mind that the MTR is best used shooting off a bench or prone while the Varmint can be used in these positions plus shooting offhand. You have to decide what your use(s) will be.

 

A few years back I read on CZ's European website that all of their barrels are made with match chambers. Having owned quite a few Brno and CZ rifles over the years, I would agree. My latest experience with a new 20" varmint barrel. Following installation I found that i was having a lot of trouble chambering as it was almost impossible to close the bolt. I measured rim thickness before and after chambering and found that the rims were being compressed measuring 0.0015 smaller after chambering; I added a shim the same thickness, now the rifle still is slightly tighter when chambering than it is dry cycling the bolt.

Also CZ advised against using CCI Stingers; the longer case can cause chambering issues and I can verify that this is indeed the case with the supermatch, trainer, Brno Mod 2 and 20" threaded varmint (I have tried it); BTW, European CIP chambers are the same dimension as North American SAAMI Match Chambers; Standard SAAMI chambers are substantially larger. Regardless, when you find a barrel that shoots for you, keep it.

 

Hello. I have a CZ457 VPT MTR. It has the Manners stock that is available with both LOP and cheek piece height adjustments. The barrel is the 16.5" version. When I purchased the gun, the 20" MTR barrel was no longer an option...16.5" only. The gun has been accurate with match ammo and noticeably better with upper tier match ammo.
The barrel is excellent as far as looks are concerned when using my borescope. The barrel appears more or less mirror with the normal faint concentric rings preceding the leade area. The bullets drop in and stop with about 0.100"-0.150" protruding. closing the bolt causes the bullet to slightly engage the lands. I replaced the CZ MTR barrel with a Lilja barrel. Both barrels borescope views are very similar with sharp rifling and they are very smooth. The Lilja is more accurate by close to 0.12" on average with match ammo. Both barrels are threaded for suppressors. The 16.5" MTR barrel would crack some with subsonic ammo even suppressed. The 21" Lilja barrel does not. That is a small part of why I upgraded though.

 

A few years back I read on CZ's European website that all of their barrels are made with match chambers. Having owned quite a few Brno and CZ rifles over the years, I would agree.

CZ hasn't claimed anywhere that all their .22LR bolt action barrels are made with match chambers. There are a few models that are made with CZ match chambers, the CZ 457 MTR being the most well-known.

CZ makes it's .22LR firearms to meet CIP specifications. CZ Match chambers will be closer to the minimum dimensions allowed by CIP specs, other CZ chambers will be a little larger. These firearms and barrels of course are manufactured in the Czech Republic.

BTW, European CIP chambers are the same dimension as North American SAAMI Match Chambers; Standard SAAMI chambers are substantially larger.

Readers in general may find it worth noting that CIP .22LR bore specs have smaller dimensions than those allowed by SAAMI .22LR bore specs, whether for sporter or match.

Glad the "aidians" figured that all out
does it make one barrel shoot better than the other?
