    I saw this "test" on the Military Arms Channel. I never would have thought that the 5.45 would outdo the 308 for penetration.

    I thought it was interesting.

    "What can we take away from this?"

    LOL, 1st thing I take away from it is not to use known under powered poor performing commie ammo in my MBR.

    I suppose an icepick penetrates better than a sledgehammer.

    Where are the treehuggers, don't they protest this abuse?

    Good point. Would have been nice to shoot some other Ammo. I'm assuming there would be a big difference.

    Sometimes penetration is more about velocity than weight.

    5.45/5.56 penetrates steel better than 7.62

    I have used an SKS-m as a makeshift chainsaw for mesquites at the ranch a time or 2.

    ETA I think circumference is the word he was looking for.

    +1; and sectional density as well. And ChuteTheMall's icepick-vs-sledgehammer comment is also dead-on.

    Got to remember that 'better penetration' doesn't necessarily equate to 'better stopper'. A 9mm fmj often out-penetrates a 5.56 fmj, and a .357magnum fmj will almost always do so; doesn't make either of them a more effective stopper than M193.

    SFCSmith - What could you get out of this? You could probably win a lot of drinks at the bar If you bring along your smart phone =)

    Not sure that I'd discount the .308 penetration. He shot it out of a gun that appeared to have a pretty short barrel.

    In my mis-guided youth in AK, I used Mossberg M500 with OObuck or slugs to cut down trees for firewood.

    A beech tree could come down with 5 to 8 OObuck rounds, so I win.

    The trees and forest looks a lot like the video!

    In Soviet Russia, trees shoot you.

    My .308 will take a deer at 300 - 400 yards, will a 5.56?

    I disagree, 308 will out penetrate 5.56 any day. 5.56 will not go through building walls (Cement/brick)..308 will.

    Somewhere I had an army manual I picked up at a surplus store. It gave rough estimates on how many rounds of various calibers would be needed to create a man-sized breach in various types of wall. I'll have to dig that back up.

    It'll take deer at whatever range you can put that bullet into the vitals.

    Absolutely, if the shooter does his part. At 400 yards, the .223 and the .308 will both drop almost exactly the same (if zeroed at 200), around 24 inches for both of them. So the holdover adjustment is the same.

    As far as terminal capability, I'm personally not as power-mad as many of my fellow Americans tend to be; so my threshold for 'acceptable' may differ from some. But for this exercise, let me ask the question this way. If the deer stood still and let you walk up to it & put a .357 magnum revolver up against its ribcage and pull the trigger, would that be an 'acceptable' power level? How about the same gun at 50 yards? If yes to either or both of those, then good; because properly loaded, at 400 yards the .223 is more powerful than a .357 magnum handgun is at 50 yards, and is roughly the same power level as most .357 magnum loads are at the muzzle. So if you believe a .357 magnum revolver can kill bambi at contact range, then the .223 is powerful enough at 400 yards. And if you're capable of effectively hitting bambi at 400 yards with a .308, then you can hit that same bambi with a .223 at 400 yards.

    No, the .223 is not equal to the .308; but it's more than up to most of the tasks that most of us face.
