Re: chronograph

Well, I was actually thinking of an emitter/detector pair close to muzzle, that would capture velocity info. The gun chronos I'm familiar with use leading edge (of bullet) detection and known distance between detectors to calc velocity. But maybe we could use one e/d pair and assume a constant (length) of our poofs. May be OK - depending upon the poof deformation/deformation variation.
