A .308 will chop through a barrier a lot faster than a .223. Turning cover into concealment.
Seriously, I have .308 rifles for a number of reasons.
1) It is a popular cartridge and I generally have at least one firearm chambered for the most popular cartridges.
2) From a static defensive position, the .308 provides more power for penetration of light cover such as a car body or windshield.
3) For a designated marksman role. I can envision scenarios where an opposing force may choose to engage at a distance and just lay in fire onto a static defense. Someone - a DM - with a .308 or similar rifle - could make that attack less effective.
4) Elk hunting.
5) In some SHTF situations, exotic animals may escape their enclosures. Zoos, wildlife 'sanctuaries' and so on. You would be surprised at the number of large dangerous animals that are in private hands. The zoos naturally have some animals that may escape and that you may have to deal with. I would rather shoot a rhino or elephant with a .308 than a .223
But the .308 is not my go to rifle, and it is not the one that I would get for each member of my group. I would have at least one, but not one for each person.
I get it. What I was thinking about when I created the thread was a couple of things.Seriously, I have .308 rifles for a number of reasons.

It's barely more powerful than the .30 carbine. come on.
1) The AK is a 30 cal round that can tear up walls, vehicles, and be used for hunting..
Not entirely accurate but ok. I said the logic and reasoning why I created the thread. There have been solid answers from a lot of people. Then there are the other ones. Valid for the people that posted them. Personally I was reminded of some things that I had forgotten about the round. Kinda happens when you read a bunch of crap from people that have no clue but know how to articulate well.It's barely more powerful than the .30 carbine. come on
heres some brain food testing was done with 20" barrels with obvious exception of the pistols.
Now that a few rough practical examples of applied force have been given, let us now examine the Big Three military-surplus cartridge calibers' energy at varying distances (.30 Caliber Carbine and two pistol calibers are thrown in as a comparison to more modern military cartridges):
Caliber, Bullet Weight, Muzzle Energy and Muzzle Velocity
7.62x51mm NATO 147 gr ~2,550 ft/lbs (3,457 joules) @ 2,700 fps (FMJ)
7.62x39mm Soviet 123 gr ~1,525 ft/lbs (2,067 joules) @ 2,360 fps (FMJ)
5.56x45mm NATO 62 gr ~1,250 ft/lbs (1,694 joules) @ 3,050 fps (FMJ)
.30 Caliber Carbine 110 gr ~965 ft/lbs (1,308 joules) @ 1,995 fps (FMJ and JSP)
.45 ACP 230 gr ~390 ft/lbs (528 joules) @ 875 fps (JHP)
9x19mm Luger/Parabellum 115 gr ~385 ft/lbs (521 joules) @ 1,225 fps (JHP)
Energy at 100 yards
7.62x51mm NATO ~2,100 ft/lbs (2,847 joules) @ 2,550 fps
7.62x39mm Soviet ~1,200 ft/lbs (1,626 joules) @ 2,104 fps
5.56x45mm NATO ~970 ft/lbs (1,315 joules) @ 2,650 fps
.30 Caliber Carbine ~600 ft/lbs (813 joules) @ 1,570 fps
Energy at 200 yards
7.62x51mm NATO ~1,750 ft/lbs (2,374 joules) @ 2,331 fps (now moving faster than 62 gr 5.56NATO)
7.62x39mm Soviet ~915 ft/lbs (1,240 joules) @ 1,825 fps
5.56x45mm NATO ~735 ft/lbs (995 joules) @ 2,310 fps
.30 Caliber Carbine ~375 ft/lbs (508 joules) @ 1,240 fps (equal in force to 230 gr .45ACP @ ~10 yards)
Energy at 300 yards
7.62x51mm NATO ~1,450 ft/lbs (1,965 joules) @ 2,125 fps
7.62x39mm Soviet ~690 ft/lbs (935 joules) @ 1,585 fps
5.56x45mm NATO ~550 ft/lbs (745 joules) @ 2,000 fps
.30 Caliber Carbine ~265 ft/lbs (359 joules) @ 1,040 fps
Energy at 400 yards
7.62x51mm NATO ~1,200 ft/lbs (1,625 joules) @ 1,931 fps (equal in force to 5.56NATO @ ~15 yards)
7.62x39mm Soviet ~515 ft/lbs (700 joules) @ 1,370 fps
5.56x45mm NATO ~405 ft/lbs (550 joules) @ 1,718 fps
.30 Caliber Carbine ~210 ft/lbs (284 joules) @ 930 fps
Energy at 500 yards
7.62x51mm NATO ~1,000 ft/lbs (1,355 joules) @ 1,750 fps
7.62x39mm Soviet ~395 ft/lbs (535 joules) @ 1,200 fps (equal in force to 230gr .45ACP @ ~2 yards)
5.56x45mm NATO ~290 ft/lbs (393 joules) @ 1,460 fps
.30 Caliber Carbine ~175 ft/lbs (237 joules) @ 850 fps
Energy at 600 yards
7.62x51mm NATO ~810 ft/lbs (1,100 joules) @ 1,560 fps (equal in force to 5.56NATO @ ~150 yards)
7.62x39mm Soviet ~280 ft/lbs (379 joules) @ 1,030 fps
5.56x45mm NATO ~172 ft/lbs (233 joules) @ 1,122 fps
.30 Caliber Carbine ~135 ft/lbs (183 joules) @ 760 fps
It is plainly obvious why so many recommend a 7.62x51mm NATO (.308 Win) chambered rifle as a primary defense rifle. It clearly overpowers all other modern, common military battle rifle calibers at all ranges and maintains a further effective range. The few negative aspects are the relatively higher recoil, louder report and heavier cartridge weight.
It's barely more powerful than the .30 carbine. come on
because star trek the next generation is more realistic than the latter.
Great thread; drilling down to the nit-noids of .30 Cal is fun....
CD has a good point...+
If a person wanted a watered-down .30 Cal, a mini 30 or a 30 Carbine may a better opion than a AK
