Grenade Throwing and how to correct the throw direction?

Ok none of my fixes seems to be working. So I created a couple videos on my phone and uploaded them to Facebook. Here are the links. Please check them out and let me know if you guys see anything that could be improved. I already thought of one improvement that could be made is that after the timeline for the damage radius elapses I should start the grenade explosion and do damage for holding the projectile to long, or another solution could be to auto fire the grenade at that point. I think that second option is how Anthem currently does it. There are two videos the shorter video shows the functionality I had prior to adding the animations. The 2nd video I go through the blueprint of the grenade setup and show where I am adding the impulse to the mesh of the grenade. Thanks for any help in advance.
