First let me start by saying you did a MUCH better job on the 2nd video. Now let me guide you on how to make a kick a$$ one.
1) Shoot at the plate
2) Shoot at BOTH of the headlights
3) Shoot at center mass
4) Pan the whole entire front of that lame van
For crying out loud keep at each of these aiming points for a few seconds. Use the Laser Atanta both modes, Stalker LZ1, Pro Laser III, etc. Use modern guns
