Last time I bought once fired x39 cases I got 250 for $40. They were all large primer.

I believe Remington is the only brass using SRP.

Quoted: Gents, I am just getting into reloading this round and I found out that the brass comes in SRP and LRP. Which is more common? I found 400 primed cases of SRP for .25cpc . Is that a decent price? I would rather use SRP as I have a ton of those I can use. I have a case of brass 7.62x39 ammo I bought last month that I will have to open to see what primer they used. Edit: looks like Norma brass. Lrp. Bummer there. There have been a couple of brands that used small primers. The small primer 7.62x39 cases are a bit stronger than the large primer cases, but the large primers are thicker than the small primers, even magnums. Large rifle primers are the standard for 7.62x39 and they are much more common. |

The primers alone are worth 10 cents in the current market, I say buy!
I recently purchased a bulk quantity of new IMI 7.62x39 @ 40 cents each unprimed and thought it was a good deal. |

With a cartridge case size and powder charge weights used in 7.62x39mm, I see no reason to not buy small primer brass.
The only problem you will have is keeping them separated. |

Remington made small primer 7.62x39 cases for a long time, but before they ended production, they switched to large primer 7.62x39 cases.
Hornady makes small primer 7.62x39 cases. https://www.grafs.com/catalog/product/productId/70440 |

One “gotcha” with this cartridge is that non-US makers’ cases sometimes have different rim thicknesses (or even diameters), and the base of the case can also be a little “off” from SAAMI-spec US cases.
You almost certainly do NOT want a “small base” sizing die if you’re going to load range brass. Chamber specs for a whole lot of AKs, SKSs, and RPKs are “generous” to say the least. In my experience, Hornady’s 7.62X39 sizing die is almost a “small base” die; I’ve goobered a lot of range brass finding that out. |

When reloading 7.62x39 brass does it require some type of harder cup "mil spec" primer to prevent the round from going off when dropping the bolt on it?

It depends on the firearm, but for AK's and SKS's, yes, mil spec primers are preferred. With small primers especially and small rifle magazine primers always a minimum regardless of the firearm, due to the case volume, cartridge pressure and firing pin protrusion. |

Remington and Hornady both have cases that use SRP. Everything else is LRP afaik.
That said... while I have a x39 AR, it gets fed steel. I've got a x39 bolt gun (Howa mini - it farkin' rocks!) that I am set up to reload for, and I wouldn't mind having 100 or so SRP cases for it. I've got 100 or so 1x firex LRP cases I could trade if you wanted to post something in the EE. |

Honestly, I just load both. I don’t separate them except when it’s time to put a primer in them. But I’m not loading these on a progressive press either. Seems like I only have a few small primer cases.
I also load both the steel cases and the brass berdan in 7.62x39. Those I keep separate. But that’s pretty obvious as to why. I’ve never had any die related issues in this caliber, but then I’m also loading for Warsaw Pact weapons and they’re a bit more tolerant. Regardless, at .22 per pc, Hell yeah I’d be buying primed brass in 7.62x39 regardless of primer size. A few hundred is enough quantity to justify having to keep them separate. Honestly it’s easier here to find small primers anyway. |

Remington used to make runs of small primer 7.62x39 cases, because some of their bench rest cartridges are based on 7.62x39 and most bench rest cartridges use small primers, even 308 Bench Rest.
The Remington small primer cases were by far, the strongest, longest lasting 7.62x39 cases, but the last couple of boxes of Remington 7.62x39 cases I got, took large rifle primers. Remington went out of business and then got bought by another company. I don't know if they bother making 7.62x39 cases now, but even when they did make them, it was in limited runs and not very often. I only bought them because of the strength of their small primer cases. All of the last boxes of cases and 7.62x39 loaded ammo from Remington I've seen, were large rifle primer cases, which is the industry and SAAMI standard for 7.62x39. Hornady lists small primer 7.62x39 cases as a current product, but only makes them in runs and they are not in continuous production. |

Quote HistoryQuoted: When reloading 7.62x39 brass does it require some type of harder cup "mil spec" primer to prevent the round from going off when dropping the bolt on it? If I'm loading steel Berdan cases, I use the Tula Berdan primers for 7.62x39. Just like loading ANY round, make sure primer is seated aprox .003 below flush.   Yes my home cast powder coated 160 gr loads in Berdan steel cases function in my AK's and AR's. With no leading, full power loads.  Pic in focus a little better. Like this. Notice primers seated below flush. This is my final QC check before putting rounds in the ammo box with a card with all load data included in the box. |

This reminds me why I need to keep my hand priming tool.
I stored my 762x39 brass with mixed primer pocket size. 762x39 brass is precious, not hard to buy but you will almost never find some once fired reloadable 762x39 brass laying on the range like .223 brass. The bulk of the brass is large primer pocket. So when reloading 762x39 if a primer doesn't seat it's a small primed piece of brass which I then hand prime on the spot and put it back on the shell plate |

I am confident that American or foreign companies will step up to the plate with brass for 7.62x39 and 5.45x39.
Our market is too big to ignore. PMC ammo was my first source for 7.62x39, later IMI came to the rescue. People underestimate the difference quality 7.62x39mm ammo can make. 2 moa has been possible with my scoped Romanian 10/63. I'm using a Leupold 2.5x M8 pistol scope mounted on an Ultimak rail. .310" Hornady SP's or .311" Sierra Pro-Hunters are excellent bullets. 24.5 grains of H4198 or 28.0 grains of H322 works for me with 123/125 grain jacketed bullets. |

Supposedly if I use the Hornady SST stuff my BCA barrel is guaranteed to shoot MOA with it. Ain't spending what I spent on the barrel to find out... but I'd expect better than 2moa, since I get 2-3moa with Wolf and Tula and Golden Tiger, which is about all I can do with irons anyway. Have a new GM barrel in the wings, can't wait to swap out and try some reloads. On the other hand, I have a Howa mini-action in 762x39... and it gets slightly better groups than the AR using the cheap steel case and I've got a very cheap crappy scope on it for temporary. Again, need to do some reloading and swap over one of my target scopes just to see what it can do. Remember - this is the parent cartridge to the 22 and 6mm PPC rounds, which hold records for small group sizes. Also the parent for 6.5g, no slouch in the accuracy department. And the front half duplicates the 303 Brit just about, which is also known to be accurate when shot in a sporter style bolt gun (not a sporterized smle) |

AR-15's chambered in 7.62x39mm are more accurate in my experience than any AK based rifle. Group sizes are usually cut in half using the same ammo.
