Meanwhile, a friend and occasional reader of the blog went to shoot the Eastern CMP Games. He shot four different courses over a three day period. His best was the smallbore.
581 out of 600, with 23 X. Here's his score sheet, minus the names.
This was good enough for a silver medal. The top shooter, 16 years old, shot a 600. Here's the course of fire. I would point out that it includes 2 strings of standing fire, one of them rapid.
