The original concept was for a "disposable" lasing element (i.e. not ruby) that would actually be vaporized when it was lased and was attached directly to the front of the round. Then came the slug, then the jacket and propellant. The goal was medium to low range, line of sight, ultra high power gun that would put a slug exactly where aimed without the need to compensate for range, wind, etc... Or is that something that isn't really needed? It may be that line of sight is not affected enough to worry about it and the ballistic stuff needs to not be line of sight. --- James Newton: PICList webmaster/Admin mailto:jamesnewton@piclist.com 1-619-652-0593 phone http://www.piclist.com/member/JMN-EFP-786 PIC/PICList FAQ: http://www.piclist.com _______________________________________________ http://www.piclist.com View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
