My 1911 has done this ever since I got it, I still reload it. These brass are probably on their 5th time being reloaded, The dents smooth out considerably when being sized and deprimed. Just wondering if anyone else has this problem

I've seen it every once in a while. It's a kink from the infeed, actually - the sidewall of the case is getting bucked a bit on the feed ramp. If you gently - GENTLY - smooth out the feed ramp/round it/polish it that'll take care of most of the problem.

Dear sweet Jesus, don't enlarge the critical dimension of the bottom of the chamber though - the 1911 already leaves the case head partially unsupported, so any further deepening of the chamber/ramp could leave you in a blowout situation.

Jussssssssssssssssstttt a little to round the upper edge of the chamfer should do it. I'm talking material removal by hand, then a Dremel with buffing compound. This did wonders for my Kimber SIS when I got it.

Nothing to do with feeding. They're hitting the edge of the port on the way out. Your Kimber probably already has the port lowered and flaired. The ejector just needs a little tuning. Either it's a bit too long, or the contact point needs to be adjusted.
 
My nork Commander does it as well... It is no cause for alarm with me, I just reload them as is and it pretty much gets ironed out between sizing and firing them.

That mark is caused by the case hitting the back edge of the ejection port, not the feed ramp. Two things you can check are.
1- extractor tension
2-ejector length and angle.
 
As well as ejector and extractor, also check your recoil spring against your load. You may be over-sprung (not enough dwell time so case can clear before the slide begins forward movement). Eliminate one variable at a time though starting with extractor, then ejector, and spring last. Don't do all three at once or you won't know what caused it.
