I don't wanna be that guy...

But you can shoot .303 bullets through them as long as they are on the smaller end (.311/.312). Sorry, had to say it :lol:
If something doesn't work, apply rule .303!

I've been interested in this cal lately, and this rifle in particular but the synthetic stock version without iron sights. The fact that factory ammo is only around the price of 223 makes it even more appealing.

Here's a link that I just came across while researching something else. http://youtu.be/jcRE5j8e-vw

I saw that video - confirms that it's indeed possible. That dude is incredibly thorough (hats off), but you probably wouldn't need gas-checks so long as the projectile was a little harder and you didn't try to push it too fast. A simple pan-lube would probably also be adequate if you weren't pushing them crazy fast.

If you want to reload jacketed projectiles for your rifle, Hornady 150g 303 projectiles are .3105" diameter and perfect for the Russian calibres. I load them in 7.62x54R for the Nagant. I have been thinking of a short rifle in this calibre, due to access to 1000's of rounds of leftover Norinco ammo, and this one looks very good. Just need a Howa owner to post his for comparison, Cheers.


If you intend to shoot mil surp 7.62x39 ammo then the CZ is actually designed for it more so than commercial brass. The CZ web site even actually states that commercial brass may have troubles in the CZ. Pretty much the reason I bought a Howa Mini 20" varmint over the CZ. I have no intentions of firing mil surp or lead projectiles in my 7.62x39.
PPU factory ammo works great in my Howa. And at $79/100 it is cheaper than the brass lol. PPU brass reloads fine. I am on my 3rd loading for some, but have only neck sized so far. Brass is still under max length.
A great projectile is the Australian made "The Bullet Factory" .311 130gr HP. Excellent groups out of the Howa Mini. Their .311 150gr HP work great in my 7.62x54R Nagant M44 as well.
Hornady make the 123gr SST that shoots great also.
Not sure why anyone would want to shoot a 150gr out of the little 7.62x39. The 123-130gr is all that's needed.

Not bad - but the again not great either. As a comparison, here's a 5 shot cast-lead 100yd group out of my 30/30:

Check the Berry's web site. https://www.berrysmfg.com/item/bp-762x39-312-123gr-sp
They state that their 123gr plated projectile is only rated for speeds up to 1900 fps. My manuals list minimum loads around 2170 fps for the 123-125gr. So Berry's needs some magical load to produce these reduced velocities. Thinking the only safe way would be something like trail boss. I have no experience with trail boss as i do not load reduced loads.
I am very cautious of playing with minimum loads, let alone trying to load less than minimum to stay around Berry's recommended 1900 fps.
I would steer clear of Berry's. And would rather try HRBC cast projectiles if I wanted to try cast. Gas checked and driving them at more suitable velocities.
I have loaded HRBC cast projectiles in some of my mil surps: 303, 308, 30-06, 7.62x54R, All gas checked, and all at normal velocities. They all worked good except some 303's. Only successful in about 2 of the 8 x 303's i tried. Some of these old clackers have terrible over bored barrels and only produced big clouds of smoke and 2 meter groups lol.
Have since given up on cast projectiles and only shoot jacketed projectiles now. Not worth all the extra hassle loading them.
Only cast projectiles i use now are in the 44 mag lever action where you can drive them full speed without gas checking the. Great cheap fun.

Tested some of the Bullet Factory .311 150gr HP in my 7.62x54R M44 Nagant today. Very impressed
Great grouping for open sights.
Great results in the Chrony.
Will be sticking with these Bullet factory projectiles in my 7.62x39 and 7.62x54R.
Will order some .308 150gr HP to try in my 308 (7.62x51) Israeli Mauser 98.

Neat rig SHV. I've had half an eye on one of these or maybe a howa for some time, but then the pendulum goes full swing & I tell myself what I really need is a lever gun in 30/30. End result, no new rifle.

Very nice.

I'm waiting for the 6.5 Grendel version to come out, though. - got cases and dies already.

Dear MickW,
I am sorry to hear your vacillation regarding 30/30 lever or 7.62x39 bolt is causing hardship, so may I offer a way to ease your suffering that I have used for many years? Find a quiet spot near your gunsafe, assume the Lotus Position, close your eyes and repeat, "I can have BOTH...I can have BOTH...I can have BOTH" before you know it, you will be at peace.

In regards to the CZ being designed to shoot better with milsurp 7.62, does this principle still apply to the .223 version of the 527 carbine? Or were they also designed for 5.56 rather than commercial .223. Either way would I be correct in saying if it was chambered in 5.56, shooting commercial .223 shouldn't be a problem?

Straight from the CZ web site: http://cz-usa.com/product/cz-527-carbine-223-rem/
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.

Our .223s will happily eat 5.56, since CIP doesn’t differentiate between the two cartridges and just has the higher pressure as its standard. So our .223s will shoot everything from the cheapest Russian steel to match .223 brass ammo.

I believe the main thing is the bullet size, 311 or 308, CZ527 carbine designed for 311, some commercial 7.62x39 ammo got the 308 projectile so the accuracy is not good ...

I have one of these rifles in 7.62x39 and it's horrible. It's been back to Winchester 3 times already. I have only shot about 150 rounds through it. Mine does not like milsurp ammo at all. In fact, milsurp ammo broke the extractor. There are heaps of these guns second hand in gunshops....Ask yourself why???? Just look at how many are for sale on any internet second hand gun sales site. This is the worst gun I have ever bought.....It's looks beautiful, however, it's just not reliable.

Most of these are second hand, AND not very old....Not a good sign when everyone is selling them.
