Replication not working properly

Im trying to replicate a simple line trace for shooting projectile purposes. The problem is when i try to replicate my actor camera rotation ( to use his forward vector ) the rotation is not smooth and is all laggy. Also sometimes the linetrace just shoot at x:0 y:0 z:0 .
