After reading this post, I went and looked at the 58 caliber Suhl/Tennessee bullet that I have in my collection. I can find no evidence of a ring around the nose of the bullet (sorry the picture is fuzzy, but I checked the bullet with a magnifying glass). Bu there seems to be evidence of a mark within the cone cavity (see clearer picture of the cavity of the bullet). I was wondering if this may have been left by the "drift" that Jim T mentioned or is it something else?
