Ahh you'd hate me, I always tilt my head when aiming which kind of has to be done because firearms and bows being kind of dangerous weapons I want them in my dominant hand (right) however my left eye is better than my right eye x_x (I have manky eyes, the left one is slightly stronger and the right one is astigmatic).
unless he tilts his head because they seem to do that in movies and games, maybe that's why he does it too? XD
Sounds like everyone had fun :D
Head tilting is required on some weapon systems, but for what Billy the kid needed to achieve on the handguns, not. If only I had a taser.
