You're absolutely correct. There is no requirement for a gunsmith endorsement on your "man card" to remove a feed ramp burr. Having said that, there have been some grievous errors made by blindly applying a Dremel tool to a firearm. Some experience working with metals would be beneficial.
My first thought would be "what caused the burr?" Fixing the burr, only to have it re-appear, would not be good. That's where a gunsmith might be able to assist, by suggesting a remedy. You then get to decide if you want to, or are able to tackle it.
Many compounds containing mild abrasives will polish, even toothpaste. Having spent 18 years as a mold maker, and tool maker, I use varying grades of diamond compound, although the suggestion already posted by Snakedriver is a good one.
Good luck with it, and let us know how it worked out.
