versatility. Shooting different calibers in both long and short configurations becomes a past time or hobby for most which in turn becomes collecting. Shooting the same gun for most could become less challenging over a period of time. The study of ballistics becomes quite fascinating for most of us which requires several calibers and guns to quench our desire to learn and experience.

because i can....

I've always said that I just need a gun for each of the animals that I hunt. That said, I've accumulated 4 shotguns due to inheritances. I also just added a new animal to hunt - hogs have finally made it to our land, so I just bought an AK 47. The bolt action model 70 just didn't throw out enough lead fast enough. Other than when I inherit my FILs guns (and add 5 more shotguns), I'll probably never buy another gun.
