Answer 1

Inserts from the link.
Using compressed air had the disadvantage of being silent, other bidders almost universally preferring a gunpowder charge/flare which would attract the attention of the stricken sailor to the direction the line was coming from. It was Crappers belief however that the gunpowder charge was the component most likely to fail in the maritime environment, and indeed this had been the case with the previous model.

Effective Range: 30 yards horizontally/20 yards vertically
Ammo: One shot loaded in barrel. Once fired takes one complete round to winch in slack cord and fire again. 50 yards of strong silk cable can be dispensed from the gun. Crapper has made some adjustments to his grappling hook, padding it with Indian rubber to silence it from clanging on brickwork when he is trying to be clandestine.

No idea which one you're asking about, but Mossberg's line gun....it simply uses a blank 12ga shell to force a rod up and out of the barrel that has the hook on the far end. 12ga fires, rod gets shot at high speed, hook flies far.
