All of the game taken is done by the law, and for reasons of management of game.  Most predators that would keep these game in check have moved on or erradicated in some cases throwing off the balance, which cause (in most cases) the overpopulation of certain species and becoming a pest. (Case in point: ask any farmer about feral hogs).

Bullet Sizes

The bullets come in different calibers(diameter), lengths, and cartridge sizes. A larger cartridge gives you more reach. A heavier bullet gives you more stomping power, but less reach (it is a matter of finding a happy medium).

Quality time while hunting

Getting away from it all and unplugging is always a good way to unwind, and to spend some time with your loved ones in the great outdoors, with no TV or Video Games they have no other choice but to interact! And you might just pick up a good trophy while yer at it.

Blasting

There is very little that compares to blasting something with a rifle, whether it could be a .22 or a .45-70 it is all fun nonetheless
