I'm making this post for 2 reasons:
1. To hopefully make more activity
2. To explain that the map and the scheme in the challenge has nothing to do with the challenge, I simply had to choose some map to get the challenge accepted.
I think many of the single player training practices could work as a fun challenge but I think this is the toughest one since you can't play this one forever.
I got the ball rolling with 4:43

Just a heads up that the map Rifle Range uses is already in the database.
