We really don't take marksmanship seriously.
Very few Armies do these days
Interesting on your opinion on 7.62 v 5.56.
I'd love to hear why ? But I am also cognizant this many not be something you're comfortable with. So I only ask in the deepest respect.
.308 is my number 1 or 2 go to round for deer and bear, .303br being the other. I understand I am using SP and not ball.
It is all about the construction of the bullet with regards to the velocity at impact.
In 7.62x51mm NATO (.308 Winchester) the shape of the bullet, the construction of the bullet and the velocity generally result in a bullet that impacts a target, and after about 18cm starts to yaw on its axis - turns a complete 180 by 36cm and continues.
Actual tissue destruction is minor - unless the bullet hits significant bone or inelastic tissue.
Whereas 5.56mm enters and yaws - then fragments - which creates a nasty wound channel - and a lot more tissue destruction.
This is also why The Hague Convention in respect to Bullet Design is horribly antiquated - because High Velocity bullets do things that where never anticipated when they outlawed expanding bullets. The Swiss argued that the NATO SS109 bullet was illegal under Land Warfare - however the key is that the bullet wasn't designed to create to inflict unnecessary wounding.

Col. Hays Parks (USA Retired) is a fantastic resource for ammunition legality, I have met the man several times, and he is truly a great person that wants the most effective legal means of tools available for American and allied Military Personnel.
However some folks are not happy about it -- they only seem to focus on the Israeli usage though - NOT the usages by NATO troops.
