Whoh, we've got some hard challenges today. More Than A Handful is easy if you go play Rumble Pit. As for the rest, I suggest doing Sniper Battle. You'll get your 250 kills faster, while getting your headshots, but it's still gonna take awhile. For Blast Radius, just chuck some grenades where the the Grunts land out of the dropship.
Good luck guys!
