    Take a punt

    How fast will this signalling cannon signal a 1" steel ball?

    It will signal with home made black powder and effective barrel length is 220mm.

    I will shoot it over my f1 and if I get a reading before I shoot it( the f1 that is) closest guess wins something( haven't thought what yet but something)
