I've never been able to master the art of really 'running' a target with the 6X scopes. When a condition I like is hanging around I try to go from target to target as quickly as I can, but I find myself pushing the conditions a little bit if I try to go too fast.
Sometimes I'm done in 2 minutes and sometimes in 6 minutes, 55seconds! Or 9 minutes, 55 seconds if we're shooting 10 minute matches. -Al
