The  Revolutionary Howitzer  was originally developed to fire bombs (powder-filled explosive shells.) This required a large bore in order to get the best effect from the larger projectiles, but it also required that the propelling charge be reduced to about one-ninth of the shell weight, in order not to over-stress the hollow projectile. Since the small charge burned so quickly, there was no need for a long barrel, and the howitzer therefore evolved into a large caliber gun with a short barrel – about five to seven times the caliber was the generally accepted figure, as opposed to 15 to 25 times for guns. Revolutionary Howitzers, like mortars, were chambered. The advantages of dropping the explosive shell over obstacles was introduced after the howitzer had entered service, and the design was soon modified to allow more elevation to the barrel to obtain plunging fire. Due to the short barrel and light charge this did not introduce any complications in the way of carriage design, although it must be stressed that in the 18th century an elevation of twenty degrees was considered high for a howitzer. It should also be added that although the elevation was increased over that of the gun, this was offset by the lower charge, and the Revolutionary Howitzer never achieved greater ranges than guns of equivalent caliber.

Hern Cannon and mortar barrels, except the  8″ Siege Mortar  and  8-3/4″ Bowling Ball Mortar , are made with Steel Liner Tubes with minimum 1/4″ wall thickness. and with welded breech plugs. For bores larger than 2 1/4″, we use 1/2″ Wall Drawn-over-Mandrel (DOM) tubing.
