I was reading the posts when I came across yours. It's extremely rare for a primer to fly off the bench and remain in this universe. Typically, and this has been verified by several prominent astro physics experiments, that a wayward primer, once it leave the bench, will 99% of the time fly directly into an alternate universe. Only when a reloader in the alternate universe loses one of his primers, will it pop back into our universe.
Glad you weren't injured.
