Re: Magpul DVD, larue mount claim
TH is a very good salesman, his job is to convince the military it is the latest and greatest. He finds the right people within the military and uses the influence of his to sell the Horus to them. Horus spends a lot money to push him deep into the right circles.
Remember he was hired as a salesman first and his instruction is based on selling the Horus, that is who ultimately pays the bills. He very effective at it. A few free OBRs or at least deeply discounted ones don't hurt either, I hear the friend of Todd rate is $1500 for an OBR if your not in a position to rate a free one. The only strings, tell everyone what a great guy, and how effective the Horus is. It really helps overlook the weaker parts of the program.
As far as the wind thing, it's okay, look up the Rule of Nines, or the British method and you'll notice some similiarities. Most of the time it's just stuff taken from the Horus software put in long hand form. The sliding scale is weak, and lack of flexibility with other calibers, but it will get you close as anything else. Though it didn't seem to help much in the video, neither did the reticle for those much discussed second shot follow up, like much of it, their counting was a bit off.
