349:"The threatening aspects of the continent required that large rifled guns should be procured for naval and siege purposes. I was therefore called upon to produce 40-pounders and 100-pounders without having had an opportunity of testing the patterns by previous trials, though I had stated in my original report that I apprehended that the application of breech-loading to large guns would involve an application of parts which would be inconveniently heavy to handle... I was at first in hopes that the same material which had been used and found to be sufficient for the 40-pounder, would be found equally suitable for the 100-pounder; but that turns out not to be the case. The vent-piece for the 100-pounder continues still to be a difficulty". Sir W Armstrong to the Select Committee on Ordnance in 1863. 567: 42: 535: 295: 285: 549: 445: 699:
72 cwt gun as its reduced 10 lb charge with the light shell was insufficient to break up and distribute the lubricator in the bore (Treatise on Ammunition 1877, page 153). The gun's later official designation was "7-inch" (Treatise on Manufacture of Ordnance 1877, page 154). 109 lb projectile is given in Text Book of Gunnery, 1887. The 1902 Text Book of Gunnery refers only to a 100 lb shell for both 72 cwt and 82 cwt guns.

Critics also considered that the manual labour needed to raise the heavy (136 lb) vent piece out of the breech before reloading was an unnecessary combat impediment. Another objection raised was that obturation (i.e. sealing of the breech on firing) depended on how tightly the gunners turned the

The gun was originally a "100-pounder". In 1861 the projectile weight was increased to 110-pound and this became standard and was used to describe the gun. In 1865 a "light" shell of 90 lb was adopted for naval service for the 82 cwt gun only, to reduce recoil. The light shell was unsuitable for the

The abandonment of the Armstrong breech-loading design led Britain to begin a major program of building rifled muzzle-loaders to equip its fleet.

On top of each powder cartridge was a "lubricator" consisting of tallow and linseed oil between two tin plates, backed by a felt wad coated with beeswax and finally by millboard. The lubricator followed the shell down the bore, the lubricant was squeezed out between the tin plates and the wad behind

As these limitations were imposed by the current Armstrong breechloading design, and as no other suitable breechloading mechanism was available, production of the 110-pounder was discontinued in 1864 and Britain reverted to muzzle-loading heavy guns. The remaining guns were moved to the role of

Although subjected to one of the fiercest bombardments of the wars, the Maori defenders were protected by anti-artillery bunkers and went on to repel the British force, inflicting heavy casualties. 662:£424 13 shillings Royal Gun Factory (Woolwich) production cost 1859–1862; £650 Elswick Ordnance (Armstrongs) production cost 1862-3.

It was considered that with a maximum gunpowder propellant charge of only 12 pounds (soon reduced to 11 lb for the 82 cwt gun and 10 lb for the 72 cwt gun) the gun was incapable of a high enough muzzle velocity to penetrate the armour of enemy ships:

To load the gun, the vent-piece was raised, the shell was inserted through the hollow screw and rammed home into the bore, and the powder cartridge was likewise inserted through the screw into the chamber. The vent-piece was lowered, the screw was tightened, a

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

The British government's Select Committee on Ordnance held lengthy hearings in 1862 and 1863 on the relative merits of the Armstrong breechloaders compared to other breechloaders and muzzle-loaders. It finally announced:
