CZ 527, 7.62x39 success

My fondness for the 7.62X39 cartridge is almost equal to my dislike for the SKS rifle.

In my bolt action rifles I load 130 SP's over 27.5 grains of H4198. I just picked up a couple pounds of CFE-BLK to try, but have no report on it yet.
 
Following the guidelines in the Hornady Handbook (7th ed.) I load 123gr bullets and 26.0gr of Re7 in my Mini-30 and Remington 799 for a muzzle speed of 2350 fps which approximates factory load ballistics. According to SAAMI standards, pressure limit is 45,000 psi, low compared to, say, the .308 Winchester at 62,000 psi. I would guess the lower pressure factory ammo is suited for the SKS and the like.

My particular x39 Ruger No.1 (only!) can safely handle any listed maximum load - plus a bit more. A muzzle speed of 2700 fps is safely attainable with 123gr bullets. :d
 
I was at Cabela's today and happened to notice they have one of these CZ 527 Carbine's on the rack. What a nice rifle! It fit me well with beauty wood and a smooth action. I'm not sure how much it weights but it seems perfect for carrying around the bush.

What is the realistic effective range of the cartridge?

Great deer round............ I load 123gr SP/25gr- H4198/Privi cases/Fed mag primers for deer [two kills] And Speer .311 /150gr can be used for heavier game with the same powder or the IMR version.The mag primers cut groups in 1/2 from standard .Also loaded 93gr cast Tokarev pistol bullet over 2.7gr of Bullseye for chickens at 900 fps/standard primers.Harold

Hmmm... you got me on the chicken round, sounds awesome, didn't think of the tok bullet! Where do you find them?

"As a general hunting cartridge, the 7.62x39 is best utilized at close ranges, employing select shot placement - adequate for shooting lighter framed game..."

My son has blazed a couple of Muleys with the x39, hornaday ammo. Single shot, couple of steps, down and done. Longest was just under 250, shortest 190. I limit him at 250 with that round, and only with a clean boilermaker shot, you could likely stretch it a few more yards but realistically and ballisticaly, 250 max. Great expansion on both though, velocity/ expansion is going to be the limiting factor on the x39...
Plus trajectory of course, much past 350 and it starts to become artillery!
 
I have had my Vz58 with red dot out a few times as my bush gun but haven't had an opportunity to try a shot yet. I've been stockpiling boxes of Hornady sst with the hopes of putting them to use. I've watched for a Cz527 but will maybe start looking more seriously now. Thanks for the reports everyone.
 
Cool little round good for close range Deer hunting in my experience. Factory load ballistics can be improved somewhat by handloading but would never equal a .308 which has about 700 fps more muzzle speed with the same weight bullet. Knowing its limitations it works fine.

I have found the Ballistic Studies site (noted earlier) seems to paint a morbid picture of most well proven rifle/hunting cartridges. Among it's victims are the 6.5x55 Swede and the .303 British. To read what was said about these cartridges would make you think these were 125 yard cartridges, 150 at best. A limit of 200 yards on a broadside whitetail is my self imposed scenario with the 7.62x39. That is my practical limit on my shooting ability as I age gracefully.

The TBR range limitation for the x39 is probably based on the minimum 1000 ft-lbs at 100 yard rule in some states and supported by their field experiences. The threshold is about 150 yards at factory load power level.

With my Ruger No.1 I can extend the threshold to 300 yards. :cool:

My self imposed limit for a handloaded bolt-action 7.62X39 is 100"ish" yards... I don't see the need (or like to) push the limits on game... that is not to say that if I see a nice buck at 125 yards I won't take the shot... my accuracy is not in question, nor is the performance of the bullet, but with it's limited powder capacity, if I suspect shots of 150-250 yards, I will carry a rifle chambered for a greater cartridge.

Agreed... really though once your outside 7.62x39 capable range your our of range for most hunters and otherwise are going at least .308 but starting who get into the win-mags etc.. short and simple it should be an effective deer round if your shooting within 150m, ideally within 100m. Beyond that distance if sniping deer in the open presents on your property use something which carries energy further.

Possible for a 150gr bullet to do 2200 fps MV as listed in the Hornady Handbook. Then the 1000 ft-lb threshold is now at 250 yards.

And nearly 400 yards with my Ruger No.1. :cool:

Post a pic with your 400 yard deer and your No.1-A 7.62X39... that will be one I want to see.
