I watched an episode of Future Weapons from season 2 that features the CheyTac 408 (thank you Roku- if you have netflix you have to get yourself a Roku). Anyway, they were making a 2K yd+ shot with the CheyTac and they were using what looked like a dedicated ballistics calculator/computer. It looked sleek and appeared to be for military sniper use. Where can I get one of these contraptions? Also, thought that the commentary was a little bogus because they threw a lot of rounds at the small target and then bragged about how amazing the "three shot group" was at that range. It's not a three shot group if you shoot 15 times and then count the three that landed on the target!
