Note, you CAN glean 7.62 ammo as well as 9mm off of badguys if they're packing the right weapons. I noticed that in the later missions that I couldn't reload my scar L hardly EVER, and instead noticed more of an abundance of (dead) enemies' MP5SD's, and FN SCAR-H's.

Also to note, here's an interesting balance note with respect to accuracy penalties for foregrips and GL's:

SCAR-L:
*GL gives less of an accuracy ding than the foregrip

SCAR-H:
*Foregrip gives less of an accuracy ding than the GL


As to power of the shot, the MR-C takes about 3rnds to down a tango if you hit CM (center mass), as compared to the 1 or 2 it takes with the 5.56 and 7.62 NATO catridges.

Variance between the SCAR-L's and H's that's worth noting:
*Both can take down a target in a single shot, it's just that the -H variant does it more reliably

The new GL range ticks are EXTREMELY useful, btw. It's allowed me to make far better first shot grenade hits on APCs and tango locations than before. This is good b/c I usually have to go on faith that my grenade hit where I wanted it to, as when I usually use the GL I'm under heavy fire and can only pop out for a quick second to approximate my shot, and fire. Usually a miss with a rifle, but with the GL and the new ticks they've put in the game, it's more likely a hit now.

Btw, has ANYONE found smoke 'nades in the PC version? They speak of them in the x-box version but I've yet to see ANY available to me, and I've played through the single player campaign completely. Smoke 'nades at certain points would have been more valuable than another frag 'nade or extra 7.62 ammo when carrying the -H.
