7.62×39 CZ Carbine. Rebarrel to what?????

[Four Fingers of Death]

This is a nice little bolt rifle, virtually a minature Mauser. It has seen a lot of Chinese ammo and I am thinking of rebarrelling it in the near future.

Any suggestions???

[Lonegun1894]

If you're open to a wildcat, or at least it would have to be treated as a wildcat due to ammo availability, how about re-boring it to the Russian 9x39? And then maybe let me play with it for a day or two?

[Mica_Hiebert]

6.5 Grendel

[Four Fingers of Death]

Both look like good options, the 9mm especially suitable for cast boolits.

Can the 6.5Grendell cases be made from 7.62x39brass?

[rollmyown]

I like them in the chambering they are issued in. Why do you want to change it?

[rwadley]

You may be able to even get it re-bored to 9x39 instead of re-barreled. If it was just a smidge longer, it would be a good candidate for 35 Remington (I read that it is just a little short).

I suppose another option is 6.8 Remington SPC. It has a slightly larger rim diameter, though.

Yes, I have read that you can make 6.5 Grendel out of 7.62x39 brass. It may be easier out of virgin brass, though. Not that it matters a lot, but I think most Grendel cases have small primers and most 7.62x39 cases have large primers.

[RU shooter]

22 PPC , 6mm PPC , 6.5 Grendel , as others have said 9x39 or the blown out version the .358 gremlin all would be suitable and I'm sure there's a few other wildcats based on the x39/ Grendel case .

If yours has the single stack magazine like the one they sell in the US, I think it would make a neat little .38/.357. It might even work as a .357 Max.

If starting with a new barrel, I would use a 5 groove with equal lands and grooves and a little deeper grooves and at .308. I would set the shoulder back on the 7.62x39 case for a longer neck wildcat. Maybe 0.10 or more. I would decide what boolets I wanted it to shoot and taper the leade for those.


Ok Sir...you can quit laughing now....But that is what I would do.....:-o

I think that is kind of like a 30 ARX (6.5 Grendel necked to .308). Or you might be able to do a 30 Remington AR (slightly larger diameter case).

Sounds kind of like a 30 ARX (6.5 Grendel necked to .308). You could also try a 30 Remington AR (slightly larger diameter).

[Earlwb]

Didn't they make a few different .22 caliber cartridges based on the 7.62x39 cartridge case? One of them would be almost a no brainer. I would likely just stick with the 7.62x39 as ammo is pretty common and fairly cheap too. Plus it is a fairly versatile cartridge too.

[Four Fingers of Death]

Keeping it standard is probably the most sensible option, with a 308 barrel, rather than the 311. I have a lot of 308 moulds, including a 6 Cavity Cast Boolits group buy soup can mould which would be a great plinker / small game option.

I like the idea of the longer neck, but I think that may cause more problems than it would solve for future owners.

It has the 5 shot single stack mag and is the carbine version with the open sights (I use a scope though).

FFoD: IMHO, Do what you want, reform the case in any way you wish, blow it out and push the shoulder back giving you what ever YOU want, and don't even be concerned with the future owners. They make reamers every day.

This is a one way ride we are on, there is no reset or do over button, Make it yours and enjoy it now!!!

Neat idea re-bore to 0.350 with a .358 groove dia, it be close to a 35 Rem / 35 BR.

[Four Fingers of Death]

Reboring is not available in Australia. Sprinter Arms in SA used to do it, but one of the brothers died and the surviving one cut back on what was offered.

[rockrat]

I make 6.5 Grendel from OF x39 brass. No big deal to me with the large primers. Gun still shoots better than me!!

[Four Fingers of Death]

OFx39?

[Screwbolts]

OFx39? I believe the "OF" is making reference to "Once Fired "

Personally I would rebarrel and have it the same caliber as the caliber is a good one for that rifle. Only change would be to have it 308 diameter like Ruger did with the Mini 14. Many have shot the 310 factory loads in 308 barrels in the TC pistols also. The original 303 Savage used that idea by pushing oversize bullets tyhrough a 308 barrel. Don't know the strength of that bolt action however. 308 bullets satisfactory for the cartridge are numerous, cast work well. The 5.45X39 Russian might be a good match but it is adifferent case. I have used a 32-20 and a 30-30 quite a bit and still think the original cartridge is a good one for that rifle. On a rebore I would go 35 as bullets and molds are so readilly available. But a 308 barrel would offer the same thing.

You'll gain a couple of grains of space when you reform a 7.62x39 case the first time to 6.5 Grendel. But its a great round once its fireformed and the shoulder is blown out.

Bruce

[Four Fingers of Death]

OF, Once Fired, of course, I knew it would be painfully obvious when I asked, but no amount of head scratching at the time would reveal it, haha.

[CHeatermk3]

I highly recommend going with the original ctg. and get you one of these:

http://noebulletmolds.com/NV/product_info.php?cPath=30&products_id=1727

They shoot lights out in my Zastava carbine.

[Four Fingers of Death]

As soon as I saw the depiction of the bullet, I thought 'that is a Ranch Dog boolit!' I suppose it must be as hther letters RD are there. I procrastinated with the RD moulds and missed out on all but the 44/230 odd grain boolit.

NOE make great moulds, I have a few of them.

[W.R.Buchanan]

FFOD/Mick: I got here late but the .35 x 39 was what I was going to suggest as the barrel could simply be rebored and I just bet you have all kinds of brass as well.

I got that there wasn't anyone reboring in AUS, but what would it take for you to send just the barrel to JES here in the states?

I don't think the shipping would be that bad unless there was a bunch of import/export BS to contend with. I know that I have had no problem shipping sights and other gun parts there form here.

Randy

[Four Fingers of Death]

Shipping the barrel to and from the US is doable, but such a nightmare that a new barrel is probably a more sensible option unfortunately.

[CHeatermk3]

For the 35x39 you'd likely hafta have a reamer made too.

[Whiterabbit]

Gotta go with 6.5 grendel if it was gonna be a bipod/scope rifle. but the wildcat with a 356/358 cal lead bullet sounds like a dandy standing offhand shooter for steels at 100 yards.

Since I have lots of standing offhand shooters already, I'd have to pick the grendel.

[badbob454]

im a horse of a different color i say keep it as it is use the money to rebarrel it and buy a new rifle.. 2 rifles for the price of 1 you have to count your time and time is money..

[Mr Peabody]

I'd stay with the 7.62x39 chamber. The .311 bore works with cast just fine, but I think I'd slow the twist down to a 1-12.

[leadman]

I have a 6PPC 15" barrel which the 7.62X39 is the parent case for on an Encore frame. Shoots excellent with groups around 5" at 485 yards but have never shot cast in it. If you wanted it to shoot cast the rebarrel with a .308" bore in 7.62 X 39 would be excellent.

[wonderwolf]

I have one of the 527 in 7.62x39...had it for a week actually, ended up sending it back as the stock cracked at the tang on the first range trip. Its at CZ right now getting looked at. I would recommend checking your stock fit if you get one in 7.62x39 and contemplate glassing the stock. If CZ just replaces the stock i'll proabably still glass reinforce it. I don't want to worry about cracking another one. Other wise I was happy with the 100 yard accuracy I was getting with it shooting Lapua, WOLF and TULA ammo

[Four Fingers of Death]

Mine must be set up right, I've run 800 odd Chinese FMJs through it without a problem. I will be taking it to the range tomorrow and it will get a good inspection. They are an extremely popular rifle here (mostly in 223 and 17 Hornet) and I have never heard of any problems (apart from the hefty price tag!). It is a shame you struck a problem one. No doubt the accuracy will improve without the split stock. The older BRNO 601s and 602s had a bit of a problem with stocks splitting (breaking clean off more like) due to the big trigger assembly which didn't leave much wood in that critical area.

[Lloyd Smale]

id say 300 whisperer but to be honest id go right back to the 762x39. Whats more versatile. Good with 30 cal cast, cheap wolf ammo can be used, even a decent shtf caliber. It can be loaded anywhere from powder puff loads like a 22 to full power ammo that decent on deer out to a 150 yards.

[warboar_21]

When the Grendel was the hot flavor of the month there were several people converting their CZ carbines from 7.62x39 to the Grendel. I had thought about it myself but the cost of the project was more than I was wanting to spend. I would've had to special order a carbine and then have a smith do all the work.

[TCLouis]

.308X39 would be my choice.

All the same except for the .308 bore.

Best selection of molds/Boolits and it will do most things one needs done.

[Four Fingers of Death]

There is also a better choice of twist rates in the 0.308" barrel size. I have been using this rifle plinking at the range and for my severely financially challenged rifle loving but non rifle owning offsider range officer and I expected the barrel to be toast about now, but it still looks fine, so it may be awhile. I still have a few thousand Norinco factory rounds, which shoot surprisingly well out of this rifle. We shoot 40-60 rounds a session 2-3 times a week, but ammo seems to come out of the woodwork regularly from guys that used to own SKS and SKK carbines which are banned now. There are not many 7.62x39 rifles around in Australia.
