Reading about this exhibit one found out that he shot for 10 hours a day, 7 days straight in a row for this record. Beneath the photo of him are some of the actual "blocks" of wood with bullet holes in them. There was also a video showing him shooting some of them. What amazed me is that HE would toss a block up, shoot it while in the air, then walk over and retrieve it and show others that it did/(didn't in a few cases) have a hole in it.
