"could it also depend on the terrain, as the 5.56mm is small can it be deflected by catching braches of trees etc....?"
Surprisingly enough, when American Rifleman ran a series of tests about ten years ago (using various thicknesses of plywood at various angles to the
path of the bullet to simulate twigs and branches), the smaller, faster rounds were actually deflected the least.
Needless to say, this report was very controversial, because it ran counter to what most people believed. Nonetheless, deflection rations seem
(at least from this study) to be more a function of velocity (inverse of course) than of bullet weight.
By the way, I think ther are two important consideration which have not been brought up in this discussion.
The first is that there are three different types of 7.62 cartridges, what I call the "7.62 short" (7.62 X39 Warsaw Pact and .30-.30 Win);
the "7.62 medium" (.308 Win) and the "7.62 long" (.303 Enfield and .30-'06 Spgfld).
Each one of these has different charcteristics and capabilities; contrary to what we read, not all .30-caliber bullets are created equal.
The second item is that the discussion seems to be based on a single-use scenario, i.e., battlefield use only.
I would think that, especially on a forum like this, one would consider the choice of a rifle as more of a survival weapon, which would mean that you
would think of it in terms of hunting as well as a sturmgewehr only.
For that, a 5.56 mm (e.g., the .223 Rem) does not have the shock value to knowck down a deer or an elk unless your shot placement or luck is superb.
For that reason alone, I would recomment that anyone wanting a rifle, even an autoloading battle-rifle, to consider the 7.62 round, preferably the
As you can see from my avatar, I have an autoloading carbine (a Kalashnikov) in ".30 cal short", 7.62 X 39 mm. However, I did, at one time, own a
5.56 carbine, the Ruger Mini-14 -- which I got rid of -- since it may have been cute, but wasn't the all-around effective survival tool I was looking
