Just as an aside, does anyone know what delay is normally involved in firing a (real) pistol/rifle etc.? I'm guessing 10mS but 50mS does not seem too unreasonable. Some of the old flintlocks seem to take about a second!

And yep I pump the pedal vigorously if there is a delay, guess its just a brain glitch. I don't think that I will forget to stop though, and I don't think I will lose sight of the target either, or exhale at the wrong time. Also the difference in hammers will not cause a firing on a heartbeat. But then again I am not you. kindest regards Wally -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
