[QUOTE="ken snyder, post: 541122, member: 26019"] It is not possible to make contact without makeing contact. It is also not possible to make contact without transfering. The major diameter of a bullet can not magically go through a smaller land diameter without leaving marks and neither can the major diameter receive marks from something it has not touched. .040 - .050 is an error. It is a very simple Idea, 2 objects can not share the same space, something has to give. With eroded lands that are difficult to find, we do not have a measurement we are supplying an opinion. Absolutely you will find .040 -.050 skid marks all the way down to the mouth if that is how far the bullet is pushed pass the major diameter. Black felt pen is useful in the field but harder and thinner dyes that are available at any machine tooling supply store is preferable. [/QUOTE]
