I was wondering if someone would chronograph a 4.5mm pellet going through the bottom edge of a coca cola can, as I dont have a chronograph and am trying to gauge the power of my cannon

i advise testing the gun on a block of wood with 3-6 layers of cardboard in front so that it is hard to get a richocete and if you use pine for the backing almost everyone has pine and this may allow you to compar the gun to a diferent one therefor geting a relitive power

Wasn't there a post about using a sound recording of your gun firing and hitting the target to calculate the velocity?
