ROUGH CHAMBER ON MODEL 70?

I just picked up what I thought was a pretty good deal on a Model 70 Classic Safari in 375 H&H. It has a HS precision stock, bedded, cerakoted,NECG Custom express sights,barrel band swivel and a steel follower. I was trying to see how the action cycled & fed rounds when I noticed the brass met with some resistance (it still fed) at about the last 1" of travel. I took a black magic marker to the brass and sure enough, it appears the bottom of the chamber scratches the brass about a 1/2" in length and maybe 1/16" width. I looked at the chamber but can't really see anything. Can this be fixed by polishing or do I have some expensive gun smithing to look forward to? thanks, jorge

Assuming it is a little burr on the chamber mouth, a strip of 320 grit wet or dry emory paper on a split stick in a drill will polish it out. If it turns out to be a chamber defect, which is unlikely, it will require more work. I just got done doing the same thing to a 458 SOCOM chamber, to polish it. But in this case, I did it in the lathe.

This makes me think that the resistance is probably the result of the case head trying to seat itself under the extractor on the forward stroke. Sometimes the feed angle at the lower right hand corner of the extractor needs a little adjusting so the case head can slip under the extractor with less drag. Normally a simple and quick repair.
