I have recently taken one of Shawn's long range hunting classes and it has put all of the things in his article in to focus. His explanation of MOA and figuring wind in the field has made me a more confident shooter. When we began class he told me that after we were done, shooting 600 yards will be no big deal and he is right. Emphasis was put on quality optics for a good reason. Optics are one of the few things where you get what you pay for. He also spent a lot of the class teaching how to be a good spotter. I learned a lot from behind the spotting scope calling corrections. I highly recomend this class if you want to get into long range hunting.
