Polish the Ramp
Okay, so my dremel tool was not used, the q-tips came out of the bathroom and by pressing down on the ramp/throat with the slide back (still installed) and accessed through the ejection port. First, dipped the q-tip in Flitz, and with cotton patches around the area to catch Flitz runoff, rubbed hard on the ramp and throat areas for about 5-6 minutes, while using multiple q-tips in the process and more Flitz. Afterwards, throroughly remove any residue with cotton patches, and clean q-tips, apply gun oil, or break-free, and then remove any residue from that.
She has ramped flawlessly with 470 rounds fired, I'm a believer. The dremel method is well worth considering, too. My handheld Dremel stayed in the drawer, and has two settings: 6,000 and 12,000 rpm and the low speed keeps my dog's nails groomed!
