For the past 50 years I have heard about the risks involved in shooting tracer ammo. The conventional wisdom is that many barrels have been ruined by firing tracers. Makes no sense to me.

All the tracers I have fired do not light until 100 yards (or more) after they have left the muzzle. If they are not lit or tracing inside the bore what difference does it make?

Here is a recent quote from this forum: "... brought some tracer rounds home, as well, and he and Dad had some fun firing them at night without proper cleaning afterward... "

Does anyone here have any factual information on the subject?
