Krupp gun

Definition and stakes

Thomas Wilhelm,  A Military Dictionary and Gazetteer

“ The rifling for Krupp guns is polygrooved, the twist uniform, the grooves being gradually narrowed towards the muzzle for the suppression of windage. The chamber in which the shot and charge rest is a little larger than the bore, though they coincide at the bottom. This makes the passage of the projectile into the bore direct and prevents the abrasion which would occur if tilted upwards in leaving its seat. Moreover, the shot is “centred”—that is, has its axis in the axis of the bore—from its entry into the gun. ”

William Greener,  Gunnery in 1858: Being a Treatise on Rifles…

“ Krupp, like many other men with valuable ideas, has been peculiarly unfortunate in his attempts to carry them out. With a vast amount of knowledge of the science of metallurgy, he wants more knowledge in the not inferior science of projectiles; the most important point being to ascertain the form of gun calculated to be suitable for new metal, of the use of which, for cannon, the world possesses no antecedent knowledge. ”
