I could see having virtually no FMJ kills with the Intervention, which is a POS IMO. How can you possibly track someone and fire at them behind cover when you're loading a new round every time?
But the others you should be fine. Maybe put an ACOG on those bad boys along with FMJ and continue to fire at people after they round corners, go behind walls, etc. I 've found even killing people behind partial cover... while they're looking out a window, going up a staircase, whatever gives me a pretty good chance at getting the penetration kill.
