Depends on the use, and how YOUR shotgun patterns. For deer (some areas do not allow slugs or rifles, so buckshot it is) I am partial to 00 Buckshot. Larger pellets retain more energy, give better penetration.
It will depend on what you are hunting and which brand of shell your shotgun patterns best.
Buckshot is a large lead shot for shotgun shells (especially used in hunting big game).
By size of the pellet.
Buckshot is the large round lead shot fired from a shotgun for hunting large animals, suck as deer (as in Bucks and Does- shot for bucks) The lead balls come in different sizes, denoted by a number. The smaller the number, the larger the shot. The largest standard buckshot is 000, triple ought, at about .35 caliber. 00 (double ought) is the most common, at about .32 caliber. There is 0,1,2,3, and #4 buckshot- about .25 caliber. Different shotguns will pattern some shot better than others. Larger, heavier shot has more range, and greater penetration.
Depends on the guage and length of the shell, and the size of shot used. It may be as few as 3, (.410 Buckshot) or as many as several hundred (10 g birdshot).

A buckshot is a large size shell that is carefully packed into shotguns. They are mainly used for hunting large game such as deer and moose. A buckshot can easily be fired without a shotgun if there was an explosion.
Yes chokes are designed to tighten shot patterns.
either 12 gauge slug or buckshot to the head.
Depends. Bird shot, buck shot, or slugs? Length of barrel? Size of shell? for most birdshot, about 35 yards, most buckshot, about 45 yards, slugs, about 100-125 yards accurately. Larger pellets can travel about 700 yards, but not effectively.

That will depend on the size of the shot, and not the gauge. Fired across level ground with the largest buckshot, a shotgun has a maximum range of between 600 and 700 yards. Not a usable range- just the furthest that shot will travel.
