    Readily available caliber for an AR?

    So I'm looking to purchase another AR, this time in something that i can feed ammo readily available from an online retailer for a reasonable price or from a shop. I have owned an AR chamber in .223, rebuilt it for 5.56, and finally rebuilt it for .300 whisper. I don't mind the .223/5.56 rounds, i just don't trust them for my own personal safety. I prefer something with a heavier bullet. Something about ~55gr just doesn't sit well with me.

    I have no intention of getting rid of my .300, but i want something i can stock up on ammo for for SHTF, and shoot for relatively cheap (compared to always having to handload for my .300, as .300 whisper is not readily available)

    I have a buddy with one chambered for 6.8, and was wondering if anybody had any suggestions on a new caliber. I will be building this one myself, so I'm not looking for anything pre-built.

    You can find ARs in all sorts of calibers, as I'm sure you know. One in 7.62N or 7.62S might fit your bill, and there is also the 6.5Grendel and some other 'exotic' ones out there. Another option might be one in 5.45x39 - this ammo is cheaper than any of the others right now and is fairly easy to find. It may not meet your "power" criteria, though...
    A man fires a rifle for many years, and he goes to war. And afterward he turns the rifle in at the armory, and he believes he's finished with the rifle. But no matter what else he might do with his hands - love a woman, build a house, change his son's diaper - his hands remember the rifle.

    I'd go with good old fashioned .308 in your case.

    Not a damn thing wrong with the 5.56, nothing at all.

    How much difference is there in a 55gr vs. a 75gr bullet? Recoil, velocity, stopping power, etc.

    i want an ar for 7.62 to keep ammo for both sks and ar, but i decided not to when i saw how hard it was to find decent mags that didnt swell when holding more than 10-15 rounds.

    i figured this would be a good thread to see where yall are getting your mags and what brand ar yall have in 7.62

    They have what they call a frankenmag where you take a steel 10 round USA mag and a 30 round AK mag cut the rivets on the top of the ak mag and then attach the usa mag on top by spot welding it to make a 30 round mag.I just use my 10 round USA mags and they feed great I've had others that didn't work very well

    I would have to second the .308. It would be available, and it is hard hitting.

    As I understand it, the .308 winchester is the civvie adaptation of the 7.62 Nato, much like the .223 and 5.56. In my research, i haven't read anything that says you cannot load .308 in a firearm rated for 7.62N, or the other way around, unlike .223/5.56. Unfortunately, i can't seem to find anything that says it is safe, either. Anybody know?

    Here's a good article on 7.62Nato vs. .308 Winchester. The cliff notes version is that 7.62Nato is slightly larger but has less of a pressure than .308 Win. Very good article btw.
