Need help with particle bullets

So I’m trying to create a blueprint that when I fire my weapon I fire off this projectile and it works up to a point until the bullet needs to move away from the gun, the bullet (projectile) get spawned at the end of the line e.g. wall, enemy etc.

The second problem is that the projectile doesn’t get spawned facing away from the player if anyone can help then this would be much appreciated. Still quite new so not sure where I went wrong.
