I have a Bushmaster AR. I'm using new Winchester brass I want to reuse. I am getting serious scoring on the case neck and small but prominent shoulder and body dents in all of my ejected brass from the ejection port (not the ground), bad enough to make me worry about brass life for reloads (or brass failure from stress risers.)

Also I've noticed if I chamber a round, then eject and inspect, the bullet has gouging on the ogive that makes me think it can't be good for accuracy. Looks like its from the sharp edges of the feed ramps.

I was thinking about carefully deburring the locking lugs and feed ramps with a dremel. Anything I should know about this, or any other suggestions out there?
 
How do I know if I have IMG permissions on this forum? I can take a pic in macro, but it'll take awhile before I do because I'm prepping for a Service Rifle match for this weekend. Luckily, I still have enough new brass.
 
I have web space. I'll post it when I can. After this weekend I'll have a pile of once-fired, and no new brass, so I have to figure something out.
