IMR 4350 is going to be way too slow.

I haven't used IMR3031, but i've used H322, which is similar.

Overall, the cartridge is a dream to reload for, especially with cast bullets.

I'm cheap and hate paying the $20-$22/100 for the bullets they sell in those fancy boxes.

Some loads for you to consider. These were assembled and tested by ballistician C.E. Harris and published in the American Rifleman (NRA's magazine).

Hornady 150 grain .308 diameter spire point
Lapua cases
Federal 210 primers
28.5 grains of BL-C(2)
oal 2.260"................................................2028 fps...................................SD 09.........................................40,400 C.U.P.

IMR-3031 and IMR-4895 will work too.

My old Hornady manual (fifth edition) shows IMR-3031, Winchester cases and Winchester standard large rifle primers. Velocities as fired from a 20" SKS.

150 grain Hornady SST, SP, BTSP, FMJ and A-Max seated at 2.220"
starting charge is listed @ 21.7 grains for 1700 fps
22.9 grains for 1800 fps
24.1 grains for 1900 fps
25.3 grains for 2000 fps
26.5 grains for 2100 fps

Sierra .311" bullets will probably give the best accuracy from AK's and SKS's.

Am I reading this correctly???Are you folks loading .308 diameter bullets in a 7.62x39???The spec on the Kalish. round is .310 or so...you better slug your bore before sending a bunch of undersized bullets down there....not to mention you probably will have more of a shotgun pattern vs. "group:".....Shrps74

ok....i am looking at my SIERRA EDITION V as i type this. all the loads, from 110 gr. RN to the 150 gr. SPT list .308" as the bullet dia tested, with the one exception being the 125 gr. SPT being .311".
also, and i quote, " As a point of interest, we tried using .311" diameter bullets in our Ruger test rifle, as well as .308" diameter bullets in a Russian SKS. Although hardly an ideal situation, both combinations performed surprisingly well".
i have never loaded 7.62X39 before and damn sure wanna get it right, and i have 1000 150 gr. SP BT hornadys on hand.
but i respect the opinion of anyone that has reloaded the caliber before. however, it does seem to contradict what SIERRA says.
so.........anyone else have any input??? THANKS!

IMR-4350 is way to slow, can't get enough powder in case to reach a reasonable velocity.

IMR-3031, will work, the case will be completely full, and a drop tube will really help. Loads will be compressed.

After trying what I had, I listened to folks here and got some AA-1680. This powder was designed for 7.62 x 39.

It fills the case and full power accurate loads are easy to assemble. Measures superb, it's a ball powder.

I shoot a 147 gr 310.5 dia surplus bullet with Wolf LR primers and AA-1680. This now my standard load.

I hope Wideners get some more of these bullets in soon.


I have also shot .308 147 gr bullets in 7.62 x 39. They shoot fine to 50 yards, the furthest I've fired them.

I worked up to 25.0 grs IMR-3031, (reduce 10% and work up, not all AK's are the same.)

Used a mix of PMC, FC, and Win brass, Win LR primer, OAL 1.195, crimped with Lee FCD. (factory crimp die)



I have 2 sizing dies, the blue one has a .3065 expander ball for 308 bullets.

The red one has a .308 expander ball for .3105 bullets.



I size cases on a Rockchucker, do case prep, and load on a 550.

Good luck

RL7, 4895,3031,BLC2, I've used them all with .308 bullets. You'll be fine

But the accuracy wont be as good as .311

As already stated you will be fine with .308, .310 or .311 bullets. Accuracy? Duno, your rifle will tell that. Yes, 4350 is way to slow for the 7.62x39. For 130-150gr bullets I like H-322 , N-130 and H-4198. H not IMR. For 125 and under I like 1680 and H-4198. R-7 is good also, just never got the accuracy I was looking for, YMMV.

I use H322 for my 7.62x39MM loads. 28 grs with a 150 gr. bullet and 28.5 with a 123-125 grs bullet, pretty standard load for these bullet weights, with this powder.

IMR 4350 and 3031 are not the best choices when it come to X39 reloading,you just don't get you best bang for the buck with those powders. I like AA1680 but nobody sells it around here and I sure not going to pay any Hazmat and shipping charges to get any when there are several other suitable powders I can get off the shelf.

My go to powder is Reloader#7 it work with any weight jacketed bullet as well as cast in the X39 although I like Alliant 2400 for my cast loads. My next choice is either IMR or H 4198. AA,RX7 and the 4198's all fill the case well,will give you MAX velocity without having to compress any loads and all produce very accurate ammo.

As far as bullet dia goes .310 are the most accurate in both my SKS rifle one Chinese which I bought NIB and my Yugo which is a 1970 refurb, .311 shoot well but nothing like the .310 the .308 dia.bullets just plain suck accuracy wise in either rifle past 50 yds.,my cast bullets shoot as well as the .310's I don't even bother with the .308 dia. bullets in the SKS rifle anymore.

reason i asked about 3031 and 4350 is because i have a coupla lbs. of each tucked away not being used for anything.
accuracy is really not an issue as the SKS is to be used as a house/front yard gun for son that lives in the country. so MOA isn't really necessary. his hunting/long range defense rifle is a 1972 mod. 70 in 30-06 that i got NIB recently and glassbedded and put on a timney trigger etc etc that will shoot 3/8" 5 shot groups at 100 yds. off the bench w/180 gr. RN bullets. after a TON of experimenting.
ANYWAY.............THANKS for all the infor and advice!!!

Most of the dies (at least originally) came with .308 expanders. I have been working with both .308 and .311 in both AKs, PSL and Nagants and have had similar results down range. The only difference seems to be (just thinking about what is going on inside the barrel) pressures. I tend to stay closer to the lower ends for the .311 loads (especially since most have been developed for .308 bullets) and a little higher for the .308. I have also been building and shooting AKs for several years and reloading for them nearly the whole time. Now I am working loads for 155 gn casted bullets just to see what I should have if I ever need to rely on them. Currently the price of 7.62x39 is hard to beat in price and even with the best components does not seem to improve over the surplus rounds so the reason for reloading them has been purely for fun.

A lot of Soviet barrels will shoot .308 bullets very well at the distances usually encountered with these rifles.

I like H335 for my 7.62X39 loads simply because it shoots well and I use it for .223 also.
