effective range of 7.62 x 39?

.303 and all the other rounds you mentioned were supposed to have been capable of stopping a cavalry charge by killing the horse. At extended ranges. This ideal was still prominent in military doctrine and thinking at the time

I'd love to read up on that, I've searched around a little and can't find anything around the design requirements of the .303 British. Could you link me to something?

At KD with a ballistic table anyone can eventually walk rounds to the target with a spotter.

There is a difference between the effective range of KD and field range without range marker and wind indicator.

762X39 out of an AK drops close to 2MOA more than than a M4 at 250 and 300m. Mis-judge distance by 50m, the probability of hitting a 6MOA trg goes down drastically with the AK at those ranges.

Everything GT said and more.
The drop gets incredible from 300m and beyond.
As a battle rifle, 250m is about right for max'ing out.
More and very experienced shooters can ring out another hundred to 150m more out of it, but it really gets iffy.

As an explanation of how bad the drop gets I use a POSP 4x scope for a 5.56mm rifle.
The scope has three chevrons for 100m, 200m and 300m for an M43 or 7.62x39mm round.
If I zero that scope for the 5.56mm round, the 100m chevron stays the same.
However for 5.56mm, the second chevron is for 400m and the third chevron is good at 700m.
Maybe this drop comparison can help.

Distance -----5.56---------7.62x39
100 -----------on------------on
200------------1"------------ 8"
300------------3" -----------a heck of a lot and on through the floor
400 -----------8"
500-----------20"
 
Somewhere on Internet I read similar about the committee between Norway and Sweden that invented the 6.5x55. To defend that peninsula - so look at map - Sweden and Norway were awesome world class navies - coastal forts, etc. - invader is likely Russia - has to first cross Finland - then into Swede mountains. In the 1890's, that was all horse drawn sleighs and wagons. How to stop invader? - shoot the horse!!! A single horse hit, going down on team of four, stops that wagon and all the rest behind it. Can have all the high end hard ass guys leading the charge into the area - they kind of back off when they do not get supper or breakfast. A single shot by a farmer or woodsman - cue the Swedish FSR - a country of rifleman. Not going to successfully invade - easily. History shows at least one example of Neutral Sweden sending troops to practice with Finns - "accidentally" left all their Swede rifles and ammo behind when they returned to Sweden - Sweden was very strictly Neutral - did not officially support one side or another. Stuff happens though, apparently...

This really just sounds like the "5.56 is designed to wound" myth

I have to say I wouldn't feel comfortable hunting a Moose or elk with 7.62x39. According to Wikipedia Adult Male/Female Moose range between 200kg and 700kg. 7.62x39 was designed in the early 1940s to kill people. Given in the 1960s the average US male (who was likely better fed than the vast majority of 1960s European, Central Asian and Asian men) weighed 75kg I suspect that it was formed around effectively killing a 55 - 90kg male (an average of 72.5kg) inside of 300m.

I Know that bullets have developed, but I just wouldn't feel ok about trying to kill something quickly that is 2.75 to 9.65 times larger than those the calibre was originally designed around (using the average weight).

However I am not an expert in this area and it's more of a gut feel than anything I can scientifically point to.

It's worth noting of course that though .303 British, 7.62x54R, 8mm Mauser and 30-06 etc. were all designed for human warfare as well and have much more power they were also designed at a time when longer range shooting was considered a necessity. All you have to do is look at the range markings on any 1850s to 1950s rifle to see the 0 - 2000m range markings or volley sights after all. So I don't think that is quite a fair comparison.

the users of the 7.62x39 do not read internet and luckily for them ... in siberia it is used on wild boar, red deer, siberian roe deer, elk or maral, moose and brown bear ...

I could have been led down a "garden path" - more than happy to hear your understanding of how the 6.5x55 was designed - for what purpose? I am just an old bush guy - when I really want to or have to kill something, I actually do want to send something larger than a 5.56 - so, seems to me there is some merit that a 5.56 is meant to wound?? It can be lethal - but, so can my .22 Long Rifle.
 
I see a lot of you guys don't know about the power setting on a SKS. All you do is crank it up to 10 and you can shoot out to 1000 meters with no problems. What I think a lot of people do is the remove the power throttle in order to put a rail on the SKS. Sure you might get an optic but the rifle is now permanently stuck at one power.

Think about it..

Why would they print all those numbers if it didn't do anything?

Just a tip for you newbs - turning the power to 10 to shoot something 20 meters away is extremely dangerous. It's like holding a 50 cal with one hand.

unless you have on the optic some different positions to shoot like the one you ve shown
 
For another comparison, here's Nine Hole Reviews video on the Iraqui Tabuk AK DMR variant. I would be curious if the the extreme range performance of a Type 81 LMG with a good optic and great shooter would be similar to this.

you need an lmg owner that is a good shot and have a great optic on it ... any dragunov style one 4x24 should do the job ...

where is murray when we need for the transformation project.

A little lol. Marstar ran a deal back when, 75$ SKS if you bought a crate of surplus ammo. I was out of the game for awhile, just getting back recently. I can't believe the increase in prices. Crazy.

I bought an M1 Garand around that time for $800. An unfired mint M44 for $400, among others lol.
