Gun design In the beginning gun design was largely by rule of thumb. For example, trunnions were made the same diameter as the calibre, the walls of the piece one calibre thick at the breech and a half calibre at the chase, etc, but no logical reasons could be given for these dimensions, for the designers had no means of gauging bore pressures, muzzle velocity, or strength of materials. Nevertheless, throughput the smooth-bore era much thought continued to be given to improving ordnance, ammunition, and to a much lesser extent, ballistics and gunnery.
