As far as cuttlefish bone is concerned, it plays a variety of different roles in the eyes of people from different backgrounds.
From the perspective of a practitioner, it is better known as Hai Piao Xiao, an effective Chinese herb that is commonly used in the treatments of gastritis and nocturnal emission;
From the owners of caged birds, budgies, reptiles, and others, it serves as a good supplement that is rich in calcium;
From a dentist, it is a wonderful absorbent that is frequently used to stop bleeding after tooth extraction or nose surgery;
From Jewelers, it is an amazing mold-making material thanks to its heat-resisting, easy-carving and casting nature.
I've seen a plumber use it as a heat shield when soldering a joint, I've seen lock smiths use it by stabbing a key into it to see and match a key profile, I've seen tribesmen use it as a tooth brush
I don't know of any seaside Gun smith uses or recipes that use it, interesting stuff though and for a deer the calcium could attract and be as said a medium for an attractant...
