How magazines are carried?

[nighthawk45]

Hi fellows I know some of you probably are rolling your eye's at this question?
Let me explain , the Vietnam era "B-52 TIPS" say to carry your magazines top
down with the bullets aimming away from you. So if your mag pouches get
shot you won't get hit by your own ammo. Now my question is, is this still ,SOP,
and if so. Why am I seeing magazines carried sideways in most of the newer
magazine pouches I keep seeing?
I've done about a dozen differen't searchs and can't find a good answer.
Hope I don't sound to stupid??? But this has been bugging me for the last couple
of weeks. And since I know SF are THE BEST at this stuff ya'll could help.

Thanks
