remington 870 12 gague
nono
A 20 gauge shotgun is enough for duck hunting if your blind and decoys are close together and you are a good shot. Around here most use a 12 gauge. The decoys are farther away from the blinds in these swamps and a 12 gauge maintains its pattern over a greater distance.
Squirrel Hunting is a very fun type of hunting. Commonly, you use a .22 rifle, Shotgun, or a High-Powered Pellet Rifle to hunt Squirrels. If you are new to hunting, I would recommend Squirrel hunting before big game. It will allow you to get used to small animals and small calibers before you move up to the big stuff. It is fun to go out with friends with small rifles and Squirrel hunt. To me, the most fun type of hunting is deer or duck hunting, where stealth is important. The two types of ways I hunt squirrel is walking around in the woods with a shotgun, or sitting by a tree with a .22 rifle or Pellet rifle. Try other types of hunting too, they are all different and fun in there own ways.
Remington express870 very good all around gun but not bad on price
A hunting guide will show you around the place you will be hunting, sometimes video the hunt, and help you with hunting the terrain.
I dont believe in all around hunting gun. It depends on the game you are after. a magnum .300 rifle would cover most of your hunting needs. A three way tie between a .22 rimfire rifle, a shotgun, and some kind of centerfire rifle that you shoot well. The combination on these three would do you well in most of the world. (but not for dangerous game, say in Africa.)
Hunting has been around since the first man on earth was around. that is all i could say.
It all depends on what you are hunting.
Hunting has been around as long as organisms have required caloric intake to survive.
around the time of the revolutionary war.
A lot of movies involve "a guy walking around with a shotgun". Without more information, we can't help you at all.
