Re:Intuitor Insultingly Stupid Movie Physics (Score 1)

I wrote the piece on silencers and if you read it closely, its says that a reduction of sound to the "fut" heard in movies can be done with "a very well designed and precision made silencer using subsonic ammunition". Footnote #4 does say that "in theory" subsonic ammunition is available for the 7.62 Nato rifle and that it would offer no significant advantage over subsonic handgun ammunition. My point: why would an assassin lug around a large sniper rifle if he could do essentially the same job with a more concealable weapon. I will happily remove the words "in theory", but the facts remain; a subsonic rifle bullet will have a significant loss of range and kinetic energy compared to a supersonic bullet. It also may not function properly in autoloading rifles. As for fact finding, I have read patents, every web site on silencers I could find, and at least one book on the subject as well as observed a well-made silencer being fired. I've had numerous discussions, both face to face and via e-mail with SWAT team members and silencer owners. I personally tested the Coke bottle silencer with 3 different types of ammunition. I have read articles on hand loading data that advised against trying to load subsonic 7.62 NATO rounds because normal rifle powder can break up into a smaller grain size and detonate if the cartridge has excess empty space in it from the reduced powder load needed for subsonic performance. Although I could have used better wording in my footnote, the site's content is based on a lot of research.
