The Gunsmith: Over what range will you fire?
The Jackal: I'm not sure yet but probably not more than 400 feet
The Gunsmith: Will the gentleman be moving?
The Jackal: Stationary.
The Gunsmith: Will you go for a head shot or a chest shot?
The Jackal: Probably head.
The Gunsmith: What about the chance of a second shot?
The Jackal: Well I might get the chance but I doubt it. In any event I'll need a silencer to escape.
The Gunsmith: In that case you'd better have explosive bullets. I can prepare a handful along with the gun.
The Jackal: Glycerin or mercury?
The Gunsmith: Oh mercury... much cleaner.
