"The hold is loaded to capacity, Admiral" (4,6)

I believe the answer is:

full nelson

I'm a little stuck... Click here to teach me more about this clue!

'the hold' is the definition.
(full nelson is a kind of hold)

'loaded to capacity admiral' is the wordplay.
'loaded' becomes 'full' ('full' can be similar in meaning to 'loaded').
'to capacity admiral' becomes 'nelson' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'full'+'nelson'='FULL NELSON'

'is' acts as a link.

Can you help me to learn more?

(Another definition for full nelson that I've seen is " hold".)

I've seen this clue in The Independent.
