Projectile only going straight even with impulse

Hello. Sorry that this is like my third question on answerhub, I am just running into a lot of problems. So lately i’ve been adding many guns into my game, and I have a problem where the shotgun (only the shotgun) goes straight. I have added impulses like I do with all my guns, and multiply it by 2222 and it is still not working.
Here is a picture of the impulse.

Here is a picture of the firing mechanism (shooting the projectile from the weapon)

Hope you guys can help me figure out how to make it go up / down. Thanks!
