Yes Gary I have. Under the powder and in the primer pockets.
I don't pull the breach block to often to give the action a good cleaning. One day I pulled the block and I found these little nicks around where the primer cups edge would be. I put it under a microscope to get a good look and I could see melted swirls like gas cuts on bullets. I pulled all the blocks from my Shiloh's and found a second block with those cuts and that was also uses with paper under the powder.
Now this was when I used Goex with heavy compression. If the hard compression held the gasses back to make them blow by the primer cups I don't know.
I know your going to ask where the primer pockets loose no I still use the same brass.
I quit doing the paper thing. All in all I don't think it has anything to do with the accuracy using them.
