I was curious whether or not anyone here has tried a lighter weight bullet while doing their reloading, I found some ballistic data and the 7.62X39 with a .90 gr bullet had what looked to me like good performance, but I am no reloader.
Anyone got any info on this? How would it preform in theory with an AK twist rate, and so on.
Any views would be great.
i'd have to guess the period in front of the nine was a typo.
what are you thinking of maximizing? accuracy? a bullet that light wont have too much knock-down power and wont like being shot on a windy day. can't say wether it would work good with the ak twist, i just don't see using a bullet that light. i was thinking of using 147gr pulled milsurp in the ak rounds, but then i thought about what a pain it would be to reload for something that was so much fun to shoot fast. i'll stick with milsurp for now. maybe when i get a good scope setup i might try some hand loading for it.

Yeah that was a typo, 90 gr. is what I meant. I was searching ballistic tables and I came across a loading using a 90 gr. bullet. I cant tell you where I saw it but the performance was pretty good. I got to thinking that it might have the similar type of performance that the 6.8 spc round has. But I am no reloader and there are alot of gun gurus here. I am pretty interested in any thoughts you guys might have, I was thinking that long range performance would be pretty good with it. I know its not going to have the knockdown a 124 gr. will have but then again the 5.56 doesnt either but has better performance at long range. Lets pretend this round were to be fired out of a 16" bolt action.
Lets hear what you guys think.
No critter shooting, just want to know what performance was going to be like with that type of round.
I can see how pistol bullets would be less accurate.
Lets pretend to be shooting the round out of a bolt action because I dont want to hear that the AK isnt that accurate and all that jazz, I know all that. I want to know how accurate the 7.62X39 can be if reloaded with a lighter bullet and fired out of an accurate platform.
The best groups I have really seen from any 7.62x39 have been right around 1 1/2"- 2 1/2". Is it the round itself or is it the platform it is most commonly fired out of.
I am going to find the data I found and try to post it.
The 90 grain bullet would be dismal as a long distance performer. Ballistic co-efficent would be low, it would shed velocity fast and the barrel twist would not be right. It could be a decently close varment gun though.

Do you now? *smirk*
Yano, I always find it funny how people poo-poo the AK accuracy. For example, my AES-10a from Century is pretty much a 24" barreled WASR-10 (yano, bottom of the barrel Romanian) with a G2 trigger set. I've scoped it and made shots on an 8 inch by 8 inch box at 450 yards, three times in a row. That's somewhere a little over 2 MOA. Don't discount the AK until you're sure it's not the right platform for you.
That said, with that tiny bullet, you'll probably want a pretty swift twist on your rifling and the AK may not be able to deliver where a custom bolt-action could. Also, if you get this thing going up around 4000 FPS (highly doubt it, but still) the copper fouling will start to get horrendous.
I personally don't reload yet, but have been working towards it and will actually be going the other direction when I get the chance. I want to do a 240 gr. sub-sonic 7.62x39 round... thinking of calling it 7.62x39 SSR (Sub-Sonic Russian).

Oh no, thats not what I meant just_a_car, the AK is a wonderful weapon perfect for what it was deigned to do, but its reputation is not for precision. I think that the Finn variant is very accurate from what I hear.
Aside from wind drift which is a problem for the 5.56 at long range also, how would a 90 gr. bullet fare?
Really I want to know what velocity a 90 gr, FMJBT would have. Besides wind drift what kind of energy would it retain at distance?
Would it be comparable to the 6.5 or 6.8? Could 7.62x39 be made for precision?
Just an interesting concept.
I've heard the round can be amazingly accurate when constructed properly and the AK can be surprisingly accurate in it's own right. All the "poo pooing" about them being inaccurate seems to come from "AK experts" who only shoot the special of the week steel cased ammo.

You know what's hilarious about my 450 yard shots?... Wolf Black Box 122 gr. HP.

My Romanian AK is not a great shooter. I have seen a few do much better - depends on the gun, the ammo, and the shooter.
I have made one-inch groups at 100 yards using my Yugo SKS, gas valve 'OFF' and a 6X scope - this using Remington and Winchester commercial 123 grain FMJ and my handloads of similar bullets in the same cases. Pretty fair, considering Wolf gives a six inch group in the same rifle. Ammo really is the key to good shooting!
There are some very nice performing wildcats and target cartridges using the 7.62X39 cases. I'd love to have a good bolt rifle to try some target shooting in using the 7.62X39. I feel this little cartridge does have great potential.
Big Dog, I have had the same results with my Yugo SKS, I was able to get four groups in a row consecutively ranging from 7/8"- 1 1/4", with a 4x scope in the prone, bag rest using Yugo surplus, I truthfully wasnt expecting those results. I had my Yugo barrel shortened to 16" also, I will try turning the gas valve off next time.
I wish I was a reloader so I could try some lighter loads, I have also wondered about the concept of using some really good handloads out of a bolt 7.62x39, but that will probably never happen.
Suprisingly I had a Yugo about seven years ago that liked Wolf ammo alot, it actually outdid the winchester ammo I used on occasion just_a_car, so thats not suprising to me.

I'm just really happy my "Melania" likes cheap food. She's so good to me.
