so I actually have 4 guns in this caliber, 3 assorted semi autos, & a CZ Bolt action...
looking at this cartridge, it sure looks similar to what all these "new" AR cartridges are trying to do... in the past, I've shot mostly steel cased ammo, so I didn't pay much attention to the cases, other than it was nice to pick them up with a magnet on a stick... but with the introduction of the bolt action carbine, I've begun buying brass cased ammo, & starting to reload for this cartridge...
I sell brass at one local gun show, & recently I bought a big box of assorted brass cases... included was a good sized bag of brass cased 7.62 X 39... in processing them, I noticed that nearly every case mouth had some sort of damage... I don't know the conditions with which these were shot, some case mouths have the tell tale dent from hitting the receiver on the way out, but lots of them have other damage ( perhaps they were treated with the respect of the steel cases, & were shot in high numbers & walked on, before they were recovered??? ) I still have plenty of the steel cases, that I'll continue to use in the semi autos... but I'm curious if any of you guys reload 7.62 X 39 that has been shot out of a semi auto, & see as high a percentage of damaged cases???
thinking if loaded "properly", that the cases should clear the rifle... of course powder charge, & bullet weight & shape will effect case "trajectory"
I really like this cartridge, & have had good luck, getting MOA 10 shot groups out of even the cheapest of steel cased ammo out of my accurized "$89.00" Chinese SKS, & do better than MOA out of my Bolt Action... one thing I do though, is not try to shoot 30 caliber ammo... I look for the correct diameter bullet
thoughts or comments on shooting & reloading the 7.62 X 39, out of the big assortment of rifles, & with the assortment of reloading components???

I have a Ruger #1 in 7.62x39 and love it. It has a .310" bore and shoots bullets .308-.311" equally well.
Also using Unique Powder and the 100 grn 32 Caliber XTP it mimics the old 32-20 with little noise.
I simply love the little cartridge. May well be my favorite #1.

I've never owned a rifle so chambered but have been sorely tempted by the left handed mini Mausers that show up from time to time.
If I lived somewhere I could still hunt, whitetails or hogs, I'd be very inclined to get one of the lefty mini Mausers, lop the barrel off to 18 or 20 inches, stock it with a mannlicher stock, top it with an old Weaver K1x or K1.5x and go hunt the thick stuff.

I had a SR Mexican 98 in 7.62x39 that I wish I had not traded. I got the better end of that trade but find I don't shoot the new rifle as much as I did the 7.62. I also have two cz527 carbines. Love them.
I think the cartridge doesn't get much love because people are more concerned with ballistic charts than real world performance. The 123 grain bullets don't have a very good BC compared to say a 123 grin 6.5mm bullet. But at 150 yards or so, it is very effective on deer.

It parented the most accurate short-range round in the world...the Palmisano & Pindell Cartridge (commonly known as the 22 & 6mm PPCs). Its stout shape and volume are ideal for calibers between 22 and 30. The limiting factor has always been brass. That’s why Palmisano & Pindell started with the 220 Russian (which is a 7.62x39 derivative.) They convinced Sako to decrease the flash hole diameter to 0.060”, harden the case, retain small rifle primer pockets, and hold higher extrusion tolerances. Nowadays, we use Lapua or Norma to form PPC. But put them next to a 7.62x39 and their origins are obvious. Three years ago, I decided to add a .30-caliber barrel for benchrest score. Problem was, I couldn’t run the .30 BR. My bolt face was “PPC only”; I had no desire to rebate rims and deepen extractor grooves. So I necked 6.5 Grendel to .30 caliber. The shoulder was improved to 40 degrees and the datum pushed ahead 0.035”. I call it the .30 Stingray. Truth be told, it’s an improved 7.62x39 on match quality brass. I’ve shot it in the same action as my 6 PPC and can’t pick a winner. They both shoot dots when properly tuned. .30 Stingrays – based on 6.5 Grendel, which is 6 PPC necked to 6.5 with the shoulder moved forward 0.070”. I turn my brass to 0.0103" wall thickness. Loaded necks are 0.329" on a 0.331" chamber. If anyone is interested, I'll send you the reamer print. Pacific Tool & Gauge also has it on file.  Long-winded answer, but yes, the 7.62x39 is an inherently accurate cartridge. -Lee www.singleactions.com"Chasing perfection five shots at a time" |

Lee, the AMU made a 30 cal round off the 6.5 Grendel a few years back. I believe they called it 30 amu, or 30 action. It was supposed to make major power factor for IPSC/ 3 gun, it was used for a year or two basically to prove a point and gobble up some incentive money that was out there for a shooter to win a major competition/ nationals with a major power factor round. A special scope reticle was made to compensate for holdover for targets out to 300-400 yards. After the incentive money went away everyone went back to winning with minor power factor guns, 5.56x45.
I’ve got a couple of the rounds as the multigun/3 gun team at AMU at the time was very good friends with us.
I use 7.62x39 brass for my Grendel brass by sizing down, loading and firing, it’s cheaper and easier to find than Grendel brass.

The AMU among many others. After the 6.5 Grendel was released, a lot of guys necked it to .30 caliber. The .30 Major, .30 Largo, .30 ARX, and .30 Walker are essentially .30 Grendels. Powder capacities are in between the .30 PPC and .30 BR. I duplicated the .30 BR on a PPC head via the Stingray's 40 degree shoulder and +0.035 datum. This allows the Stingray to hold ~1.2 grains more than a straight .30 Grendel. Doesn't sound like much, but my upper node is 3,020 fps with a 114 grain bullet. -Lee www.singleactions.com"Chasing perfection five shots at a time" |

0late this summer or early fall i'm going to a cz 527 in 7.62x39. singleactions.proboards.com/thread/23607/7-62x39-ruger-mini-30 it will, someday, be my close cover deer rifle, when i can no longer use big bores. i have shot the new and old 6.5's, 7mm's, 30 cal... galore. the 7.62x39 i just plain forgot about it. maybe it was because of my army days. i was a op-4 for a few months and i was completely in awe of the cartridge. more so than the ak-74 in 5.45x39. i could shoot the -47 about 350 meters(about 380ish yards)consistently at a man sized torso target(prone and sitting) using open sights. or the 7.62x39 was an "assault rifle" not a hunting gun. was i wrong on that one!!! you gotta hand it to the russians, they came up with a suitable cartridge for deer and man. (suitable to me means a cartridge that goes roughly 350-400 yards and impacts a man's chest/stomach.) the cheap steel 122-125gr fmj, sp, hp factory loads are so-so accuracy wise. you can find that wolf fmj is more accurate than tula hp. and vice versa. i am planning on handloading my cartridges. i will take a bullshop .313" 165gr rn gc(11 or 12bhn) and rel7 or h322 with starline brass. i'm only going to use rifle about 150 yards, 50 yards and under is more to my liking, but not to the deer's liking  . steel cases have berdan primers which "can" be reloaded, but i would not reload these. www.gunsholstersandgear.com/2013/02/14/reloading-steel-cases-reload-steel-case-ammoif the cases are brass and boxer primed, have at her!!!! |

My 2 complaints about the CZ 527 are that the magazine is right in front of the triggerguard, at the balance point for carrying with one hand, and that the open sights that come on the rifle are rudimentary at best.
To me, it fit the role of powerful enough to hunt caribou while being a handy lightweight rifle. Adding a scope would take away from its good small rifle qualities. I think it would be closer to ideal if it came with a good peep sight.

I think it would be closer to ideal if it came with a good peep sight. heres a couple i like peep sights. i have a 1898 springfield armory(bubbasized) in 30-40 krag that i put on a redfield 102k peep sight. my best group is 3/4" at 100 yards(5 shots/benched). i average about 1 1/2"+/- at 100 yards. it used to 2 1/2"+ at 100 yardswith open sights. it luvs the 165gr ranch dog(173gr actual) and 25.5 of h4198. my son and i have killed deer out to 173 yards. most of them are killed at 50 yards and less. |

I don't find the magazine to as much of an annoyance in the field as it is in theory. I actually like the Carbines as truck guns due to the Magazine, they make loading unloading super fast and easy.
We all have our preferences.

I am needing a light recoiling deer rifle and have been considering the 7.62 x 39 (also a .357).
Where I hunt, if you do not get a DRT, it is VERY helpful to have a good blood trail. This makes full penetration/exit wounds pretty important.
Are those 125ish gr bullets getting pass throughs?
