Everytime I play deathmatch, I tend to use a sheriff more often, then switch to vandal in the last 10 kills. Most shots I will hit, but when players start strafing I can't hit a single shot with the sheriff or vandal. I hit aimlab for 30 min a day, and I'm currently diamond 2. It really destroys my mental when I watch pros hit 1 taps on moving targets but I can't hit a single body shot. How do I work on this?
