Maybe powder

[Unique]

I’m looking for different powders that’ll work well with 7.62 x 39.
It’ll be for an AK47 and be using Berrys 123 grain spire point bullets.
Thanks in advance

Accurate Arms #1680 is the best powder I ever found for 7.62x39mm. I used it often with my dearly departed CZ 527M/CSR. It also worked well in a Czech vz-58.

Best is probably AA1680, but you can probably find some data for 4227 and 4198 also as very close alternatives . W680 is another if you ever find an old can at a gun show.

I’ve had good results from H335 and BLC2, but 1680 is my main powder.

I used accurate 1680, it ran fantastic. I looked at cfe blk, supposedly it only runs well with compressed loads.

[armoredman]

The only data I have for Berrys bullets in 7.62x39mm was for the 125gr FP, 25.5gr #1680 at a COAL 2.17 ran at 2270 FPA, and is simply listed as "good" in my notes. That is nothing but my note, academic purposes, etc.

Ok fellas. I’m looking for a powder to use for my Ak-47 with the berrys 123 grain spire points.
This is the powders I have if any of these would work.
IMR 4198
H4350
H 4895
Tire Group
H380
H322
HH4227
Reloader 25
Target
IMR 4064
IMR 4350
H 4198
IMR 4227

My best results came with CFE BLK for the 122 - 125 gr. bullets. Of the powders you have I would start with H322. H322 worked well for me with 150 gr bullets. My rifle is a SKS.

[georgehwbush]

the H-4895 will work well, but i don't have load data on it. it's burn rate and density are very close to that of Accurate 2200 which i also good for that. that's all i have any exp with.

the reloader 25 is way too slow unless you want to re tune the gas system the imr-4350 is also too slow to function cleanly. the imr-4064 will probably work ok.

[Unique]

Well, I may have to get some CFE BLK

[georgehwbush]

oh, and if you have to buy powder for it. the reloader 10x is good and works very well in 5.56 ar i was quite pleased with the sub-MoA results i got from it pushing the 55gr V-Max. in my psa-5.56 m4 carbine 1:7 sub minute at 125yds from that seemed like noteworthy stuff. anyway it should push a ak's-7.62 just as well, though maybe a little less accurately.

[P Flados]

Either 4198 and either 4227 are in the right burn rate range.

H4198 driving hornady's 123 sst has worked magic in the 7.62 x 39s I've shot them in.

[jetinteriorguy]

If you’re looking for alternatives to 1680 I’ve had good luck with H335 and BLC2. H335 is probably the easiest to find.

[Shadow9mm]

I used accurate 1680 with good results.

My hornady manual shows h322 with a max of 28.5g at 2200fps, out of the powders you have, that would be my choice to start with.

[armoredman]

Accurate Arms #1680 is the best with 7.62x39mm, I used it for YEARS.
I do have ONE load for the stuff you have listed, used 28gr of H-4895 with the 123gr Berrys FP bullet, COAL 2.165, gave 1830 FPS and the notes say it worked well in my vz-58.

[Unique]

P Flados Would you happen to know min to max charge weight and over all length ?

[Unique]

Thank you all.
I’m gonna try with what you guys have suggested with what I have first before I buy any other powders

[totaldla]

Definitely the 4198s imo.

[CarJunkieLS1]

CFE BLK CFE BLK CFE BLK btw did I mention CFE BLK.

It is handsdown the best powder for the 123/125 grain bullets in the 7.62x39 case. I am sure A1680 is a great powder also, but once I got my hands on CFE BLK no other powder comes close.

2000 FPS is the max for Berry's 123 Spire Point. Using most published data will typically push the bullet well past 2000. I found the best results with IMR 4198, 23.1 grains which maxed out at around 2000 FPS out of a 16-1/2" barrel. The best group out of the Ruger American Ranch 7.62X39 was with 22.0 grains of IMR 4198, which resulted in 1900 FPS muzzle velocity.

Two bits...

Thanks everyone !!!!
I just received my RCBS dies today and the mandrel in the die was .307 and the other one was also a .307.
