Home Forums Hunting & Shooting AR and Tactical Rifles 7.62x39 revisited

??

Didn’t see that posted.

Your quote. Does short range thumping a bit better. Just curious why you feel that way.

There is no way I would spend that on a AR upper in 7.62x39... Over Christmas, I bought a radical arms 7.62x39 AR and I have been stunned by it... i bought it for 420 for the full gun. Have not had the first malfunction yet and it shoots inch groups all day long at 100 yards... The only thing I think I am going to do with it is replace the trigger... I would look for a Radical arms one on sale if you want one in that caliber.

I just picked up a BCA x39 upper for just under $300 shipped.

Gunna test it out soon.

Because it’s a fact, regardless of any feelings different.
Because 154gr and .311 ARE more ‘thump’ than 90-110 .277s, at short range from short barrels, when it comes to all around use, penetration, etc.

I’m a huge 6.8spc proponent, but once you get short on barrels, the larger bore and heavier bullets have physics on their side, when it comes to maintaining efficiency longer. Therefore, I run a RD and a stubby 7.62x39 for short stuff. I run a LPV and 6.8 for short to much longer stuff. Some overlap. Some not.

Gotcha. Some feel that way. Even though lots of energy can be lost going out the other side. One of the most amazing things to me is how well 223 with 40 vmax in the ribs kill pigs up to about 150 pounds or so. Evidently it dumps all its energy right there quickly. While the 6.5 Grendel pigs run further most of the time.

Its all a good thought. More of this or that on paper. I was just wondering if you saw it with your eyes and what difference it was.

I’m not real sure why you’re trying to conflate simple physics with some ascribed ‘feeling’, or moving the goal post from a common game bullet criteria to an energy dump theory with some anecdotal stuff thrown in?….but I’ve seen my share of stuff shot with a lot of different combos. I’m not even referring to any of that. That’d be anecdotal. Inside 100-150 yards, the 7.62x39 and factory ammo will work as well as a lot of other choices….hogs or deer. The 6.8 (and a lot of other stuff) will eclipse it after that. Nothing in a bore smaller than 308 has 150+ grain factory fodder for an AR. Exits are a thing.

As well yes. But you said thumps harder.

That was my simple original question as to what you saw that made you feel that way.

As for factory, have rarely shot factory in probably the last 30 years so we play with whatever we want. It does limit folks though.

Personally I like the X39 round. I've seen a lot shot with it but own only a couple chambered as such. I think with it there was no reason for the 300/221 to come back to life.

Regardless not much goes very far when shot in the correct place with the correct bullet for caliber.

FWIW the only rounds on game, and most of that is big game, that I"ve seen that you see a reaction every last time is 40 caliber and a above. Not pistol rounds. But rifle calibers and not small ones.

Thanks for the conversation and your time.

FWIW, the reference was with regards to short, pistol length barrels. With the inherent velocity loss, ALL lose effectiveness vs their 16”+ performance. We can argue how much, and how much it matters, but the physics are: the larger the bore vs the case capacity, the less velocity loss in shorter barrels, AND more bullet weight is more bullet weight….long barrel or short, slow or fast. So, (at short range) the best the 6.8 can do in barrels much shorter than 16” is to roughly equal the 154, x39 in energy, with less bullet weight….and usually, the x39 is gonna exceed it. That’s just the numbers. Then there’s the energy dump ‘theory’.

The way I see it, the 6.8 and 7.62x39 are far more similar than different.

If one isn't up to a task, the other probably isn't what you are looking for either.

Thousands of people tried to kill me with the 7.62x39. They never hit me, even at close range. Most paid for their stupidity with their lives. -Hint-

Good thing they did not know how to shoot for chidt. No flies on the 7.62x39 in the accuracy department, nor it's lethality. Be thankful those gooks don't practice their marksmanship like Americans do.



That rifle doesn't shoot like my AR's, but it's not bad. Was shooting it last year at a steel yote set at 400 yards, and making consistent hits on it, with irons.. And to my eyes, that yote looks like a black blob at 400 yards!!

To hell with the 7.62x39

I'm grateful for the 7.62x39,if only as a source for the GOOD stuff. Hint...............

I’ll take them…. Others can take the commie case as original

Ruger Mini-30 100 yards

Oh please don't use that thing. .. hint.. please.

I agree there. Especially if you compare apples to apples. IE both 7.5 inch barrel or 10 or 16 or 20...

Frankly it just doesn't take much to kill a pig or a deer. I would not hesitate to hunt with a 22lr for deer if legal. Do it all the time on pigs..

Whiskey might be right. In a 6.8 bolt gun 22" can run the 110's at 2800 fps with a long mag. Comparing same case necked up to .30 and same barrel length, should be able to run the 150's at 2300 fps with H322 the same powder. The 150's have better SD, more weight, more diameter, but go a lot slower. I think up close the 150's from a .30 caliber might be better. The 7.62 x 39 and 6.8 SPC have similar case capacity.
