CZ Factory Barrel Accuracy
      #73970 - 16/03/07 07:10 AM

Can anyone please comment on the accuracy of CZ factory barrels? SPecifically, the 375 H & H in the 550 Magnum. Alternatively, would it be recommended to get an after market barrel?

Thanks

Can you add a location to your profile ???
so we know what country / state you are in.


Re the question, Excellent accuracy
- and they last a long time.

CZ make good strong accurate guns.

I have a couple of 550's and more 602's
and they all shoot well.

If buying, try to pick a gun from the shelf
as opposed to ordering it in

Thank you. I updated as requested. I spoke with the President of CZ-USA today and she answered my questions concerning when she thought the company would be offering 550s in LH for 375 as I want to use it as the basis for a custom project.

Shall I assume from your response you would not buy an after market barrel but would rather be equally satisfied using a factory barrel? Also, the 550 in 375 comes in a 25" tube. Would that be too long for all round usage?

Thanks.

Yes, Keep the factory barrel - after all, why change when they work. And, if you buy the gun as the basis for a cusom project, you cn shoot it first to see that it shoots !

25" would be a great barrel length - nice and dandy IMHO.

Cool. Thanks for the input. If you don't mind my asking what exactly (er, if anything) would you change or improve about the 550? At this point your comments would actually free up money to direct at some good optics. The project is actually for my Dad and I. We have two lovley claro Walnut blanks (his is fiddleback and mine crotch-figured) that we intend to use. Looking at the gun I think I would perhaps talk to the gunsmith about a couple of crossbolts in the stock and a different bolt handle; I like the look of the longer straight ones.

Have you ever had a stock custom built for you? Did it make a difference? How about in terms of perceived recoil? BTW, our choice of 375 is based upon a desire to have one rifle to cover all of out intended sporting applications although I did recently see a beautiful 450-400 NE double...

All I can say: I own a 602 ZKK 375: accuracy is a lot better than most marksman could handle (hunting wise that is). It is quite capable of 1 MOA from the bench (it comes with an original Carl Zeiss Jena scope with integral mounts)
Of course, no two rifles are alike

JSL3170.

I own a CZ 550 in 458 win Mag. I have fired about 550 rounds through it with no problems. It is more accurate than I can shoot. There are two things I would do if I had the money at the moment. I would get the action slicked up and the feeding ramps altered to make it 100% reliable feeding. I have had failure to feed on several occasions when I have been in a hurry in competition. It is unexceptable for a DGR. The second thing I would have done is have a custom stock fitted. At the moment the gun is very comfortable to shoot, but the handling and comfort can certainly be improved by fitting a custom fitted stock. If you already have the blanks, it certainly will not cost much to have it made. I think they are a great rifle for customising IMHO and mine will receive the above in due course.

This is great! Thanks for the input. BTW, it was our gunsmith who got us onto the action. I have spoken with the President of CZ-USA in the last day or so and I will move on my gun when the LH is available. Our gunsmith is www.theworkshop.net if you care. I'll pass along your suggestions. Would you, like 500Nitro also be OK with a 25" barrel for general hunting; i.e. hunting in the woods and also hunting in more open terrain?

Finally, I have spent considerable time studying "Rifles for Africa" by Gregor Woods and there is lots of good stuff in there. In 375 would you try to develop one soft-point load for all applications? If so, what would you do? A 270 grainer or a 300? Would you load it down a bit and flatten trajectory with the scope?

Anything else you would care to share about your experiences with this caliber would be quite welcomed.

Cheers.

Jeff

Re Barrel length

I've hunted in the North of Australia - untig Buff and Pigs + culling Buff -and have used a large variety of calibres / guns - DR's and Bolt's. Some of these were also used to test bullets.

One of the guns I used was a Frankonia 9.3 x 64, long barrel job. IMHO, it was too long whereas all the other BA's I've used have been 25, 26" and they are great, fine. So generally, I have come to prefer barrels on the Short Side.

Bullets
Big Game - I prefer Heavy for Calibre Round Nose (as opposed to pointy shape) as I feel they "hit" harder, open up better and the extra weight gives more penetration. I AM NOT A VELOCITY FREAK so I tend to push heavy for calibre bullets at average to high speed. Kills everything I've shot.

I did use a 375H&H on a cull a couple of times -a Jeffrey Scoped 375H&H and it was devastating !.

Hope this helps. Ask away if any other questions.

Every .375 I've had, no matter whether it was a H&H, .375/350 or .375/06IMP (2), all bullet weights from 235 to 30gr. shoot into a 2 1/2" circle at 100 yards. Every one of them has shot individual groups of under 1", inside that 2 1/2" circle.
: Disregarding the 235gr. Speers, the remaining 250, 260, 270, 285 and 30gr. all shot into 1 1/2", so, you could have several different bullet weights for different game aplications, with never having to change the sight setings. Shooting iron sights from game positions, all have exactly the same point of impact.
: BRNO/CZ barrels have always displayed exceptional accuracy for factory barrels. The only time one would have to consider replacing one with a custom barrel, is after wearing one out which is highly unlikely except in varmint calibres.
: My BRNO's always were and now includes my CZ are the most accurate 'factory' rifles I have or have fired.

My only experience with a 375 H&H was with a Brno 602. I used this rifle on pigs, goats and culling other animals on a permit. It was very accurate with all bullets and as Daryl said, it grouped most of them together. I liked the 270 grain Hornady for donkeys and Brumbies. For purely spectacualr kills on pigs and goats was with the .375 winchester 220 grain big bore projectile loaded up to 3000 fps. I know this was not meant to be driven at this velocity, but it became my "Varmit" load. I took a lot of rabbits and a few foxes with it which helped me get used to the rifle. This load was good to shoot, very accurate and was a spectacular killer on lighter game. Over gunned, never. The 25 inch barrel never worried me and it balances the rifle quite well including the 550 in 458.
Go with what you want, but see if you can handle or shoot a few first. Try anything you like through it, it is part of the fun of learning.

Hello Wayne,

Thanks for the post. Here in Maine the snow is melting fast and the temps are rising. Already only 5 months and a week to the first goose season! Yesterday, my dad and I were in a large outfitter's here and they had two 550s - a 375 and a 458. Interestingly, the 375 said "CZ 550 Safari classics" and was missing the barrel band for the sling swivel unlike the online catalog for CZ here in the states, www.CZ-USA.com

At any rate, even though I am LH the rifle mounted to shoulder beautifully! I liked how the rear island sight was intergral to the barrel. I actually liked the 25" tube. It wasn't cumbersome in the least and the balance was great. I did, however, think the stock was awful; ugly and quuite blocky in my hands. But who cares as we already have ready stock blanks waiting.

Interestingly, the guys we were chatting with told us they much preferred the 375 to the 338 WM (which was our original choice) in terms of shooter friendliness. They also thought based upon their experiences in alaska and Kenya that the larger bullet offered a noticeable difference especially on the larger fellows they tackled with it. It was again reported that barrel accuracy was top quality. so, we'll be buying one soon to send to the gunsmith and then waiting on CZ's intro of LH later in 2007 (as told to me by Alice Puluchova, Prez of CZ-USA, last week). Thaks for the input.

So, what is the terrain like where you live? Many different species to chase? If you like doubles you may also appreciate the last guy we spoke to last night:

He offered us a gun he owned. It was a 500 BPE made 1883 or 93 ( I forget as I was a little bit enthralled!) by Joseph Lang and Sons of London and was a Best quality gun. Pretty neat to hold such an item. It was a real beauty and he reported it as a good hunting weapon. Currently on sale for $4750.00 USD.

Jeff, it is very dry here at the moment as we are in a bad drought. 25 degrees Celsius. I do a lot of hunting for ferals like rabbits, foxes, pigs, goats. I hunt Sambar deer, Red deer and Fallow deer. I am hoping to head north for scrub bulls and buffalo next year. I shoot in the Big Game Rifle Club. Look on the Web for Sporting Shooters Association of Australia (SSAA) and check out the site. I use a Ruger #1 in 450 nitro, Brno 550 458, a Baikal 9.3x74R DR, 1900 BSA 303 SMLE, Ruger #1 .243 with a Leopold 6.5 to 20 scope for general hunting. Until very recently, I hunted all of the above plus Donkies, Brumbies and Camels with a bow and arrow. I have given the archery away for several reasons. I enjoy the rifles much more.

The Black powder Double sounds realy good. I would buy that instead of the Brno and use it for hunting. It would be a investment as well as a hunting rifle.

I also agree that I would rather shoot a 375 instead of some 338 mags.

Great to hear form you. Let us know which way you go with the rifle.

Wayne

The double sounds good value.

I'd also buy that - you can buy a CZ anytime,
Good DR's come along once in a blue moon.

Out of curiosity, if you were willing to spend the dough on an action what would you use? Let's assume the same 375 H & H caliber for the same applications; general big game usage. In other words, would you use something different from the CZ? If so, is it due to some shortcoming of the CZ or another reason?

personally, I would stick with the Brno and keep the rest of the money to buy a double. It depends on how much you want it and if you want a custom rifle. It is a decisi only you can make. I would prefer a double if I could afford it.

I recently bought a CZ550 in 375H&H. After having it pillar bedded, adding a cross bolt, having barrel recrowned (it needed it)and a few other minor things; I am very happy so far with how it shoots. Am in process of getting some reloads but with Federal factory ammo (300grain) at 100m I got a 1.25 inch 4 shot group using a Leupold 1-4 scope set at 4x (picture on right on it's side)and a 3shot 5/8 group at 50 m.(300grain Federal ammo) I am going to try and post a shot of some 50m groups and the 100m groups; I am only doing this as it is my first attempt at posting a picture.Hope it works.

Yeah, I'm looking around at a few after market components but I like your sentiments about the actions itself. You might enjoy this one: go to www.huntamerica.com and on the left column see "Talk Forums" then proceed to "Hunting in Alaska" then see entry number 6 entitled "Polar Bear Attacked but her survived..." Ghastly stuff, really. lucky is what I say. I recall hunting with a guide one time who had a few photos of a polar bear hunt he made in the far north of Canada and the bear he brought down was so big he could not get his arms around its neck. The photo was of him behind and to the side of its head and it's no joke, its neck was larger than his chest.

we're travelling to the gunsmith's in a couple of weekends so I'll post the stock blanks when I get there and as I go along I'll keep posting the various stages of this fascinating project.

As for the next gent below, yes your photos came up and I'll remain curious about how it goes with the loadings.

Jeff

A friend of mine has a CZ in 375 H&H.

We have shot it on paper at 100,200, and 300 yards.

It shoots just fine.

Great! Another good report on this rifle. I was just telling another forum member I was looking at one the other day at an outfitter's and I was really impressed with how well the gun mounted and how I liked the feel of the barrel. Funny - holding that gun in my hands made me feel like I was holding a rifle that was quite well designed for practically any hunting application. Why don't more people seem to know about this seemingly great caliber? Well, whatever the reasons may be I am looking forward to getting one when CZ puts out the LH version later in 07.

500Nitro,

I was speaking with someone the other day and they mentioned a "1920's Sari Rifle Barrel Contour". Never heard of such a thing. He told me it included a barrel bandfed rear sight. Any ideas??

CZ factory barrels are very accurate , I'm in my second CZ Lott ..
This one has been slicked up a bit ..

Two things on this one that my friend had "fixed" before I got it :

1) three crossbolts , probably not needed in the 375
2) reshaped the bolt handle

There is a CZ firearms forum that used to have LOTS of discussion about the rifles and the issues they came with from the factory. I haven't been on it in a year or more.

I am not beating up on anybody's favorite gun here, but I used to spend a fair amount of time on the CZ forum and I can tell you that poor bedding, feeding, cracked stocks, etc seemed to be very common complaints, as well as frequent references to poor factory service.

This was a few years ago.

The guns themselves everybody raves about after the sloppy factory troubles are alleviated. I have one CZ only, not a big bore but I've had my troubles, too.

I personally do not mind fixing bedding problems and muzzle crowning and feed adjusting, etc myself. Others do not have the knowledge or desire to do so. If you find yourself in the tinkerer category I'd say CZ's are GREAT rifles, as the basic actions are really sound, sturdily made and have excellent potential.

If, however, you are a guy that wants to open the box and have a guaranteed 100% perfect gun, go elsewhere. Others have potential problems too, but the CZ's seem to have a reputation for a certain crudeness of manufacture and for needing TLC right out of the box.

I caint say for certain about now , but you're right about sloppy finishing touches several years ago .. My other Lott CZ was one of the first to come over the pond .. Back then , I knew of 2 375's and one 416 with split stocks before the first magazine was emptied .. Along with sevreal other minor ( here , major on a hunt ) issues ..

As a mater of habit , all mine are worked over not long after I get them .. CZ or any other brand ..

Short of spending 3-4 grand or more on a custom rifle , I think the CZ is the best foundation for the money to work from ..

One thing I like in the CZ Lott is , it's a 5+1 ..
