Muzzle loading air rifle?

Clearing a muzzle loading rifle with high pressure air. This Parker Hale Whitworth .451 rifle has a stuck ball and needs unloading manually.
A build up of fouling had prevented the bullet being seated down as far as the powder charge.
Extraction with a clearing rod and worm had failed. The rifle was then brought to the Wirksworth Gunroom for me to clear. Firearms, compressed air and workshop tools can be dangerous in unskilled hands. Don't try this at home.
