A rifled breech loader (RBL) is an artillery piece which, unlike the smoothbore cannon and rifled muzzle loader which preceded it, has rifling in the barrel and is loaded from the breech at the rear of the gun. The spin imparted by the gun's rifling gives projectiles directional stability and increased range. Loading from the rear of the gun ...

In the United Kingdom, these problems surfaced in the RBL 7-inch Armstrong gun a.k.a. the 110-pounder. This was an early British 178 mm rifled built-up breech loader. When the problems could not be solved, production of the 110-pounder was discontinued in 1864, and the United Kingdom reverted to muzzle loaders for the higher cailbers.
Springfield Model 1866 breech. The Springfield Model 1866 was the second iteration of the Allin-designed trapdoor breech-loading mechanism.

The 21 cm RK L/19 was the later name of a rifled breech loader gun of the Prussian Navy. This gun started with a massive gun barrel, cast from steel in one piece. In 1868 a built-up gun barrel version was tested in Prussia and found to be much more powerful. Many of the massive guns were then changed to built-up guns.
The new technology involved required higher standards of gun maintenance and gunner training than the British army was prepared to provide and as a result the gun had a reputation in service for unreliability. In 1871 Britain reverted to muzzle-loading guns, such as the RML 9 pounder 8 cwt, which were cheaper and fired much cheaper ammunition.
The gun as first made weighed 72 cwt (8,064 lb) but the heavier 82 cwt (9,184 lb) version, incorporating a strengthening coil over the powder chamber, was the first to enter service in 1861. It was intended to replace the smoothbore muzzle-loading 68-pounder gun, and was intended to be Britain's first modern rifled breech-loading naval gun. The ...
