each weap technically has an "autoaim" however Yas 7k has an autolock range of 180 degrees (compared to a 35-45 degree for other weps), but in turn has the bullet range of a shot-type weapon.
Yes yasminkov 7000 does have shotgun-style autoaim. Yasminkov 7000 w/ hell was/is a popular weapon and was the inspiration for making Asteron Striker, so that hunters could have a hell yas 7k of their own.
