What is the barrel length, and what is the gas system length.
Several threads on this type of phenomenon, it could be due to more or less normal things.
The ejector swipe can be from the sharp cylinder edge on the ejector plunger, many have polished or even chamfered it slightly on the inner part of that edge towards the firing pin. For the "marks on the brass" do you have some pics or describe it further.
Primers can flow some into the firing pin hole during firing so this does not necessarily mean cratering.
Brass markings on the side... usually need pictures, some milkiness on the sides - some guys don't like, usually from a rough chamber wall.
Small nicks on the rim can come from extractor radius points being too sharp. You can try to carefully sand or file them down a bit to get rid of the sharpness.
If I have this correct... others may chime in also.
Pic's are worth a 1000 words.
