Kaur,
Thanks for the links. Chief Warrant Officer Haugen is very well known in SF circles. His bio and indepth knowledge of firearms can be found here:

BTW, the boomershoot folks add a whole new meaning to long distance marksmanship (Precision rifle shooting at exploding targets)

The typically tranquil community of Teakean-Cavendish will be shaken up as nearly 200 people gather in North Central Idaho for a weekend of explosives and guns at the 9th annual Boomershoot, April 28 - 30, 2006.

Diverse shooters and spectators from throughout the world are expected to attend Boomershoot, including law enforcement officers, scientists, engineers, computer programmers, and members of the Boeing Pistol & Rifle Club. Others are gun rights activists, such as Stephanie Sailor, three-time Illinois U.S. Congressional candidate (Independent), known for running cyber campaigns on a $0 budget.
