I really liked seeing the shock wave trace. I've only seen that once before at the 300 yard range. It was pretty amazing to see the bullet path and how vertical it is at point of impact. It really shows how being off a few yards in range estemation would really screw you up.
By the way, what kind of bullets were you using? Sierra MK? What ever it was they were pretty effective. I have used 30-06 soft points, 12 Ga slugs and 50 cal. round balls and never had any better results.
