Gaseous, its like many other activities. Some people are into shooting and guns for utilitarian purposes and nothing more, and others pursue it for its own enjoyment as a hobby or sport.
My dad loved to hunt game and fowl and he was an expert marksman, but only had a handful of guns and rarely shot more than a dozen rounds of everything all year long. One .308 rd = one deer. A couple of 12 ga shells = one pheasant.
I on the other hand have a variety of handguns, rifles and shotguns and enjoy the history, culture, sport and hobby of guns, shooting and reloading as well as the utility of guns for hunting and self defense. But if it wasn't for my Dad's respect for guns as tools I may never have developed my interest in them either.
