Conference Call and Striker work great for this.

From what I understand, even before you unlock the challenge, the game still registers those long-range shotgun kills while you complete Open Wide. So you don't have to start from scratch once unlocked.

Most Hyperion shotguns should work fine.

I believe it is 750 kills at close range to complete level 5.
