[QUOTE="VinceMule, post: 2505531, member: 122164"] It looks like the reamer picked up a chip in the body area. As you can see, the reamer was retracted from the barrel with the barrel still spinning, which is NOT GOOD! Also, the area in the neck and shoulder loads up the reamer with chips, and the chips scored the shoulder real bad. There were so many chips in the chamber that the chips were trying to do the cutting. Most probably cause was the reamer was not retracted frequently enough, cleaning the chips out of the chamber, and off the reamer. The type and quantity of Cutting fluid used is another issue. Some cutting fluids will not allow a chip to weld to the reamer flute. I am sure that shallower cuts, in the beginning, looked horrible also, if anyone was looking. That shoulder is the worst I have ever seen on a chambering job. Everyone has a bad day. Send the gunsmith these pictures and see what he says, I think that he was having a very bad day. His day will get even worse when he sees that brass. The chamber should have been looked at with a AA flashlight at a minimum or better yet a borescope before the barrel was taken out of the lathe..
