What is the effective range of the 7.62 x 39 round? If fired from the Type 81 LMG using its IRON sights. Is it possible to hit a 2 feet diameter iron plate at 300 yard?
 
Hi Bob

Yes, yes it will do that, I have done so regularly, it should hit every time. However wind and the user's ability to operate the...disgusting iron sights that the Type 81 uses are the factor here not the calibre or really even the firearm outside of the sights.

When you ask the effective range of a calibre and firearm it's definitely worth noting the use just like you did. Effective range is an extremely subjective thing. For example with the modern 5.56 rifle it's seen as about 3-400m for the individual but 600m when groups of you are firing. Use drives everything :)

Thank you! So the round itself should be good enough to reach the iron plate upwards towards 500-600m?
 
9.Hole Reviews is the go to for realistic long range potential.. it's and SKS but should be representative of barrel length for caliber.

 
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.

Doctrinally AK was a SMG replacement.

AK has a battle sight setting marked cyrillic letter P (looks like horseshoe, means constant setting). It's about 300m. Aiming at the belt buckle will produce hits to the torso at 0-300m.

400m is max supersonic distance. Which is technically the max effective distance.

many victims of the 7.62x39 wish im pretty sure that they read you about the 400m limit: unfortunately in the hand of shooters knowing the distance and how to shoot it s way more ...
 
i put rounds on a 2/3 ipcc steel gong 9/10 rounds on average at 500m with a 4x optic...


sks with irons on ipcc target at 300m is no issue either.

i put 7.62x39 out of a howa mini action on a 2/3 ipcc target at 600m... thats getting dicy for me... only about 40-50% hits at that range.

7.62X39 drops about 35" from 300m to 400m, vs 556 from a M4 drops about 20", when both zero'ed at 200m. On average that's about 9" for every 25m.

25m range estimation error is easy without range finding instruments. The only way to correct this is adjusting thru spotting.

I will be super optimistic to do this on my own without some sort of range finding instruments when challenging targets at that range, expecting hits within the first 5 rounds.

that s a challenge we need to find out.

but you re right without the proper tool less doable but still. ... with the proper sights and distance measuring really doable but need practise of course.
 
Out of desperation i just bought some 150gr JSP from Western Munitions. Normally I like to hunt with SST, but I cant find any in stock rn (during hunting season go figure :p ). Will be interested to see if it groups more accurately out of my SKS. Im slightly worried that the 150gr traveling at slower speeds will be less likely to expand to the extent that the 123grs would. Just to be on the conservative side, i think my effective range this season will be about 150m lol

Fair one, I enjoy hunting with my CZ527 in 7.62x39, though my Tikka lets me take the shots past 200m
 
ah for sure hunting is different but some here will tell you you cant use it for moose or grizzly while in russia they do not think 2 times about it ...

Worked fine on last years moose with 123gr Privi.........I load 150gr .311 Sierra SP's as well in a CZ527 carbine

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.
 
.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
