Dimigod's Longrange shooting

Dimigod's practical long range shooting guide is by far the best how to, and equipment review I have ever seen.  He takes the time to discuss everything from Mil-ing to optic selection, and more.  He gets involved with discussing the physics in bullet coefficient, but stays simple for new enthusiasts.
