brass for 7.62x39

Hello Scarletfire, welcome to THR.
Yes, the S&B brass would be good for reloading.
I'd suggest you find out the bore size of the barrel on your CZ as that would tell you if it may perform better with .308 or .310/.311 bullets. In 7.62x39 you may find all of those sizes in projectiles.

Those are good brass. Privi would be my first pick though. Their brass is top of the line IMO for durability if we're not talking about match brass.

I have used MANY different headstamps in my CZ 527M - the only ones I have trouble with is Fiocchi - REALLY tight primer pockets! I have great luck with WInchester brass - some of those have ten plus ejecter marks on the rim from the vz-58 in the past, still going strong. Jacketed bullets .3105 and cast bullets sized .311 seem to work just fine.

The bore on the cz 527 is supposed to be .310, and S&B makes some good ammo. There brass works great and lasts a while. Winchester ammo also has some pretty good brass.

The only "problem" I've encountered with S&B brass is there is very little chamfer on the primer pocket mouths. No big deal I just give the pocket mouths a quick twist with my countersink to break the edge...

i have loaded .308 bullets for my .310 bore AR in 762x39 and have good luck with them

Product Description
The Carbine is an intermediate range ‘brush gun.’ Weighing in at less than 6 lbs, this handy rifle has a straight comb walnut stock and open sights. For a long time this was our only model chambered in 7.62×39 (now joined by the 527 Youth Carbine), it combines low recoil with effectiveness on medium-sized game such as deer and wild boar, making it ideal for younger shooters. Both chamberings offered in the Carbine are economical to shoot given their service rifle heritage and the availability of surplus ammunition.

Built to CIP specifications, our 7.62×39 chambers are ideal for shooting steel-cased surplus ammo. Designed to shoot .311 bullets, some American brass ammo may not perform as well as the imported steel-cased variety because of SAAMI brass dimensions and varying bullet diameters.

yes, i have read that product description and have only shot euro/russian steel case ammo.
does anyone know if the S&B or PPU is manufactured to CIP specs (as opposed to SAAMI)?
thanks, Bob

I do not know for sure with today's "Global Marketing" have to check where any ammo is made.

JMO but in a bolt gun I would just neck size the brass after it is shot in YOUR rifle.
But then that brings up the debate of FLS vs Neck sizing. But for hunting I would think it is "good Enough"

Question for you guys that load this round. What kind of accuracy is the round capable of in a quality gun like a CZ?

Definetly sub moa like anything else. The cartridge is as good as anything else common when loaded with quality components and shot in a quality gun.

Mine does well enough, far better than I can shoot it.

Don't know about a CZ but my Mini30 with a .308 bore will shoot MOA at 100 YDS with Hornaday 123 SP if I do my part. I would bet you could do much better than that given a little load work up time with a quality bolt rifle. You can't go by accuracy of a worn out barrel in an AK or SKS with 7.62X39 IMHO.

PPU makes a good brass donor. Generally a little cheaper than S+B
Target Sports USA has some decent prices on it and offers free shipping on case size orders.
