Feed Ramp Lip Damaging Bullet

As shown, my barrel and upper Arnt a perfect match up and there is a noticeable lip towards the center, the outside edges feel fine though. This is causing small dents to the bullet.

I’m not having any feeding issues but would like to get rid of this so I can have the best accuracy I can.

Idk if those small dents are enough to throw off anything but if it’s going to affect my accuracy at 500 yards I want to fix it. What’s the best way to fix this issue.
