How do I push characters with projectiles?

Currently I have a large projectile. I would like for that projectile to push the AI character I hit with it. Regardless of the mass of my projectile, or the speed at which I shoot it, there is no affect on my AI character. I have tried adding impulse, but that doesn’t seem to work. Launch also doesn’t seem to work in a way that seems physically accurate.

Nothing will move the AI character. Not even large objects in the scene with mass far greater.

I have tried enabling Simulate Physics, but this just causes my AI character to fall over, and I really want the character to continue running commands while being able to be pushed and slid around the level by physics collisions.

Anybody run into a solution for this with blueprints?
