Is there truth to the rumor that poking a file inside the barrel will alter the marks on future test firings?
I don't know the answer to this one, but my best guess is, A) yes, but not enough to alter the test firing, and B) whether or not it did, it would be strong evidence of an attempt to screw up such a test. There are few (no?) legitimate reasons to harm one's gun thusly. I have heard, but have not evidence for, is that with use, these characteristic markings change. As a result, putting 200-300 rounds through a gun at the range is enough to alter its identifiable barrel markings sufficiently to defeat forensic matching. Don't know, just heard, but it sounds reasonable. S a n d y ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
