While preparing some mil-surp brass, I am finding a good number of cases with extractor swipes on them to the point they bind in the shell holder on the reloading press. Some of them have brass from the rim pushed up into the extractor groove, and on others the brass from the rim is pulled down past the face of the case head. Some cases exhibit both defects on them. 

Is there any available tool that can clean up the extractor groove and case head face?

I use quite a bit of both 5.56LC and 7.62 brass. When I run into this issue I usually just use a small file to clean up any burrs/extractor marks. If it's real bad I will just discard the case (dispose in the brass recycling bin).

Probably SAW-fired brass. Toss it if it's bad.

If it doesn't fit in the shellholder, I don't screw with it.

I have used a file on some, was hoping for a faster more efficient tool/method. I have both 5.56 and 7.62 so, not all fired in a SAW. Either way, not tossing 10K + pieces of brass.

I do the same as Keith.  Either clean up by hand file, one slow piece at a time... or toss when too bad.  You really don't want a rim ripping off your case in the chamber on that once in a life-time hunting opportunity.

PS: Lots of 7.62 NATO Mil-Surplus brass is fired from the M240x series of machine guns, as there aren't many (comparatively) 7.62x51 rifles in use anymore.  The 240 is brutal on brass - especially when the headspace is a tad long.

CH makes a match trimmer that uses an open ended chamber style holder for a shell holder. You can use this style trimmer to square the base as long as the body is not bent or dented to badly. The turning handle works with an electric drill. I use this trimmer in prepping my match brass.

Can you send a link to this product please?  I looked at Midway and didn't see any trimmers for the case head.  Very cool!
