Yep, .30s when it counts and .28s when I feel cheap or when I'm only going to be engaging in close.
And there's nothing wrong with having a VSR as a DMR, you don't have semi auto but you make up for it by having wicked accuracy, and you can rack and snap shoot fairly quickly with a VSR. And it DOES come in handy in a firefight, as most people tend to think of a person as less of a threat, they'll be shooting at your buddies with LMG's and AEG's first while you pick off the enemy one by one by shooting them in exposed elbows and arses
