Dude, use a fusion rifle sometime. It shoots a spread like a shotgun except the spread rises up with recoil. To shoot someone from a distance with a fusion rifle they need to be standing still, crouched, or barely moving. It's amazing at short to mid range but isn't meant for long distance. This is the last time I'll say this: if you're getting one shot with a fusion rifle from across the map you are standing still or barely moving.
