Unfortunately, or perhaps fortunately there were few armoured ship-ship actions of note during this sort of period involving British ships.
The only battle was that of the battle of Pacoha, where The Chilean armoured turret vessel "Huascar" fought HMS Shah (an unarmoured frigate) and the Amethyst. Despite being hit 60 times by the Shah and the smaller Amethyst (Shah was an iron hulled/wooden sheathed vessel, the Amethyst was a wooden corvette) the Huascar was unpenetrated partly due to the British ships having no armour piercing shells. The Huascar survives to this day as a museum ship (it was British built).
This is where the ramming bit comes in, as in the Monitor/Merrimack fight, it was thought that armoured ships fighting would not be able to do sufficient damage to each other and a ramming attack might do the job. This had caused damaged in the Battle of Lissa (1866) between mixed bag of armoured and unarmoured Austrian/Italian ships and was thus seen to be a valid tactic.
Unfortunately these sorts of actions led to false conclusions, and were studied to death more often enough drawing the wrong conclusions.
Interestingly the Huascar and Monitor suffered the same burden of not having their turret armament capability at 100 per cent effectiveness.
The other issue was the ships were obsolescent as they left the slipway, having been made so by technical advances as they were building! The admiralty did not want to launch fleets of unbattleworthy ships and thus small and different batches were produced.
