*Has been fixed as of the v1009 patch. The turn speed is almost a lock on now.
Killing Floor 2 early access ver1006 - Basically what happens is that scrakes don't follow your position as fast as other zeds so you can keep him in a loop where he's constantly turning without ever facing you.
Using this, zerkers are excellent scrake killers as even if there's multiple left you can aggro 1 from a far enough range then stun with right click pulverizer then run him in circles and left click until dead.
Keep in mind though, don't do this constantly in an online game. Just use an EMP and spam to death as a team, only resort to this if your party is fully dead and you're the only man alive or if there's no ammo left as you only need 1 pulv shot.
FP's however constantly are facing you so this technique will not work. 2x EMP and team spam.
