I'm loaded, but money's stolen (8)
I believe the answer is:
buckshot
'i'm loaded' is the definition.
(I've seen this before)
'money's stolen' is the wordplay.
'money's' becomes 'buck's' (as in a US dollar).
'stolen' becomes 'hot' (stolen goods are 'hot').
'bucks'+'hot'='BUCKSHOT'
'but' acts as a link.
(Other definitions for buckshot that I've seen before include "I may be fired" , "Large lead pellets" , "that could kill a bird" , "Projectiles for hunting game" , "ammunition deployed?" .)
