If you are not shooting a suppressed weapon...

What makes 300 AAC Blackout better than 7.62x39?
Link Posted: 7/20/2013 12:29:27 PM EDT

Straighter case walls.

Everything the same as for 5.56x45 except the barrel.

It's more easily shot through AR style rifles? Same mag, bolts, ect.

Can you find me some cheap 7.62x39 reloading supplies please?  Thanks!


Oh wait!

I don't own one, but from a handloading perspective it's seems brass and bullet selection are much better. Especially bullets

If you reload, better selection of bullets to choose from.  Easier to tailor the rounds to what you intend to use them for.

How much does it cost to reload 1000 rounds of .300 vs. buy a case of wolf 7.62x39?

Cause AR15.

Better bullet selection. This isn’t important if your goal is to do magdumps, But it makes a big difference if you want to do anything else.

Works better in an AR platform. This is real important if you are already invested in the AR-15 and don’t have any AK stuff. (Magazines and parts become real easy to get)

And, look at it like this. Outside of being able to get crappy Russian ammo at a decent price, why is the 7.62x39 any better than the .300.

Straighter walls is a good thing?  Doesn't a tapered pin (cartridge) fit into a tapered hole (chamber) far easier and more reliably than a straight pin into a straight hole?  What am I not getting?  ...Maybe straight magazines operate more reliably than curved ones?

Kinda what I figured.....

I would think you could roll your own using heavier 7.62x54 bullets......

To me having a .300 BO is to be able to use a suppressor and without subsonics...it's kinda pointless.

That is what the .300 BO has over the 7.62.x39

Non subsonic wise, platform is everything.

Using 90% of my current parts is a bonus.......changing the  barrel is a snap.

Easy



Pistol powder vs rifle powder.



300 BLK is built for short barreled rifles.  The powder cooks off in a 7 inch barrel, no fireball.

300 BLK is far superior at  blowing up 5.56 rifles than 7.62x39 because 300blk will chamber into and fire in a 5.56 rifle.

Other than that, 300blk does nothing better than 7.62x39.

Please take no offense at this, but: you DO realize a .308 diameter bullet won't fit where a .224 bullet goes, right?

Or am I missing something?


ETA: Okay, I can see where this could happen. Never considered this. Hmmmm.

Yup.
The bullet will get shoved in the case if the crimp isn't tight.

Loose crimp and very short loaded case length with short, light projectiles, gorilla punch on the forward assist....yeah, it could happen.
Much as a .40 S&W can fire out of a .45 ACP barrel, but with much less tragic results.

Straighter case walls= works in 223 magazines and the AR15 magwell.  7.62x39 doesnt feed well in a magazine that fits an AR15 lower.
