I'm aware of that, which is why I said
I've been doing a lot of thinking..
5.56 may be plentiful.. but I reckon most of what you'd find in a worst case scenario would be normal .223 as opposed to M193 or M855, unless you sought out the corpses of police/military personnel, assuming there are any and they have 5.56 on them.
So, there goes the advantage of 5.56.. at least in my mind.
Sure, I could stock up on thousands of rounds of M193, but really.. who could carry that much with them?
And as I've already said, I won't be buying a .308 for SHTF.
Ammo is much more expensive(At least for anything worth a damn), heavier, has more recoil..
Try to imagine getting into a firefight while using a .308, and not being able to use your hearing protection.
Now, I know x39 and 5.56 are both very loud themselves, but there is no denying .308 is louder.
I imagine most people wouldn't keep standing after being shot by either x39 or .308.
I couldn't take full advantage of the extra range with that round, anyway.
I want to keep the rifle as compact as possible, so I won't be using a scope.
