How can let my bullet push the cube?

Hi,

I use the projectile movement to implement my bullet and I really want my bullet to push the cube.
There is my setting for my bullet and the setting for my cube.

Clearly, my bullet is 100kg and my cube is 10kg.

However, when I shoot the cube, my bullets are bounced back and can’t even push the cube.

Bullets don’t have sim physics and you’ve set them to world static, which they shouldn’t be.
