If a sniper rifles a bolt action. Then bolt action only requires 2.5 seconds to point the gun at your target, fire and work the bolt action.
I have a feeling that some of the complaints about the RoA is because of beleive that each round is 10 seconds.

Rounds
"Each round represents approximately five seconds, regardless of how many characters are involved."
I feel that to point your gun at a target, fire and work the bolt action is too much for little over 1 second.
