Testing my 40mm mortar

Описание: A test of my new black powder mortar, using around 350g of coarse granulate black powder (the test was successful :D ) It's a shame, that the wind blew the smoke from the safety fuse directly infront of the camera, obstructing the view, but I'll make another video as soon as possible. Mortar dimensions: inner diameter = 40mm, outer diameter = 60mm, length = 600mm
