    .223, 5.56, or 7.62X 39?
    which on is cheaper to shoot?
    I am building an AR and thinking about chambering it in 7.62 because i also have an SKS that is 7.62.

    X39 is by far cheaper to shoot. And to keep this from getting nasty I will just say that one leaves a 22 caliber hole and the other leaves a .30 caliber hole. Myself I like the X39. One of the main reasons is I like the guns they go in. Especially the SKS and AK. Also I use my X39 for hunting so I am prolly impartial their.
    This is just my .02 but I would build an AR in a COBB lower that way you can switch the magwells out and go from a .22lr all the way up to 338 with the same lower. But that is just my opinion
  3. Southern is right on the ammo expense of the 7.62x39, board, though relatively inexpensive .223 can also be found if you keep an eye out. The .223 is also less expensive to reload if you're into that activity.

    In terms of usefulness, I would have to say the 7.62x39 is more practical. It can be used for hunting up to deer sized game at reasonable ranges, while the .223 is really only good for varmints (or people!). By the way, the .223 Remington is the same cartridge as the military 5.56mm Nato.

    A lot of AR's have a problem feeding 7.62x39. But if you want similar potency to the x39 you might check out the .300 BLK uppers.

    Personly I'd pic the 223 run some horady 40 great vmaxes.

    But I bet there all good full metal jackets would probly be least destructive.

    A hit between the eyes makes the question moot. Be more specific, are you looking for the flattest trajectory, the largest hole and/or biggest end wound, most economical round to buy or the one that delivers the most energy at the target.

    When all is said and done it runs the 5.56 best and that should be the major criteria if you are going with the AR platform.

    7.62X39 will most likely be the cheapest to feed.

    I'd hate to be at the other end of any caliber. I'd say go with 5.56/.223 because of the low recoil. Russia doesn't even use 7.62x39 anymore, they've used 5.45x39 (similar to the 223/5.56) since the late 1970's.

    Some time ago I had a semi automatic rubber band gun capable shooting multi calibers from the same breech. Low recoil and very cheep to reload. Only accurate at close range but capable of putting an eye out (so I've heard).
    Best uses: Shooting the occasional kitchen counter cat, and being a bad influence.:D

    7.62x39mm. Reason being that it's bigger, therefore a larger wounding pattern. I've heard somewhere that the 7.62x39mm round tumbles too. I don't think I'd want to be on the receiving end of either, but the reason for going to smaller calibers is because the rounds are smaller, therefore a soldier can carry more ammunition. Plus the rounds like 5.56x45 and 5.45x39 are lighter recoiling than the 7.62 rounds.

    The cheap 7.62x39 is either surplus or Russian made. OK for plinking and you don't really have to clean an AK anyways, so the black gunk that builds up from the Russian rounds isn't necessarily a problem. Good quality hunting ammo will cast about the same
    as other .30 cal rnds.

    Inexpensive surplus amma can also be found for .556. And with the right bullet, frangible for varmint or heavier expanding rounds for game, the .556 can be even
    more effective than the AK round at the longer distances. And since you have to hit the target for the round to be deadly, I would give the edge to the .556.

    FYI

    There are some differences between .556 NATO military and .223 commercial ammo.

    Deadlier for what? You are set up with 7.62 and if you add another caliber to the mix the cost will hit you dead in the wallet. The 7.62x39 is available at a cheaper price than the .223 so your cost will be lower. Buying only 1 caliber ammo is cheaper than buying multiple calibers.
    As far as killing power, you would need to state for what use; the .223 will likely have more long range accuracy, the 30 cal 7.62 will have more short range punch. What are you looking for?

    It should be noted that the 5.56 should not be fired in the 223 while a 223 can be fired in a 5.56. The 5.56 being slightly more powerful and loaded hotter.

    What is more deadly is what hits the target and most AR's are way more accurate than a AK. Since you already have a SKS in 7.62 I would go with that caliber as both are great calibers. I was wondering if SKS's can use the same magazine you will use in the AR? That would be a factor too.

    What would you be doing with this rifle? Hunting? Target shooting?
    I must say that the 7.62x39 is one caliber I do not have and if you are going to be into target shooting maybe someone more knowledgeable about the 7.62x39 can mention if they make real accurate loads for that caliber. I know they make great 75 and 77 grain Match loads for the 5.56/223. If you go with the smaller caliber I would think you will go with a 5.56 chamber?
