BB bastard makes heavies, oh and it could have allot to do with you hop up.
Though I am assuming your measuring your FPS w/ .20s and 170 meters per second and realize thats 557 FPS which is very high.
I hope you are either not gaming this rifle or are aware of things like an MED or have taken a sniper course. Cause that is extremely high.
