I have a 50%+ accuracy in most shooters I play that keep track of that sort of shit. Snipers for me, but I wouldn't call it "stealth". More like "Hey, I'm over here. Try to get to me, I dare you."
There's a reason my weapon of choice in MW2 was the EBR. Fast, accurate, and still powerful enough to one shot people, or, at worst, two shot them. Easy enough to double tap the trigger when you know you're not going to get the headshot.
