I must be gimped -- I rarely get 40% aimed shots in PvP with 1k AS using a Snakemaster.
I don't know where you people get off saying AS is 40% all the time, because it's really not. More like 10% of the time, maybe.
Or perhaps some guns have a higher chance at getting huge Aimed Shots than others. I don't really know how it all works, I just know what I get in PvP and rarely, rarely will I AS an Enforcer for 40%.
