The staff here at KestrelMeters.com has selected two books and a DVD, all from Bryan Litz, that we think are must-haves for the long range shooter.  Bryan is the creator of the Litz library and founder of Applied Ballistics, which has partnered with NK & Kestrel to integrate his ballistic software into the Kestrel 4500 pocket weather meter.  

His bio reads:

Bryan earned his Aerospace Engineering degree from Pennsylvania State University in 2002. For the next 6 years, he worked for the US Air Force on Air-to-air missile design, modeling and simulation. In November 2008, he left the government and became the Chief Ballistician for Berger Bullets. Bryan founded Applied Ballistics and has produced numerous articles, books, and videos related to the science of long range shooting.
