The correct answer is Super full.
With standard chokes, Full Choke is the tightest. However, there are non-standard chokes for SOME shotguns (used by turkey hunters) that are Extra Full Choke.
Full
A pattern of a shotgun is determined by the choke at the factory. Some models have a variable choke that makes the user able to change the pattern.
To focus the pattern of shot.
The Choke of a shotgun is the amount of barrel restriction at the muzzle end which affects the shot pattern. A full choke will keep the spray pattern of the pellets closer together farther out than if the barrel was not restricted at the muzzle. If there is no restriction at the muzzle, the choke is said to be cylinder choke or cylinder bore.
They came in various barrel lengths and choke combinations. If it is not marked on the side of the barrel, you will have to pattern the shotgun to determine the choke
You will have to experiment with different loads from different makers and different chokes. Doubtbul that one choke will be the best at all three ranges.
The TIGHTEST choke (which is smallest) is the Extra Full. The largest (no choke at all) is known as a cylinder bore.
A choke is a device placed on the end of a shotgun barrel that changes the pattern of the shot as it leaves the rifle.
from smallest pattern to largest: full improved modified modified improved cylinder cylinder (no choke)
There is a tool known as a choke gauge. It is a tapered length of metal that is placed in the bore, and measures the width of the muzzle. Or- shoot the shotgun, and determine how it patterns, Purpose of a choke is to to open or close a shot pattern- and proof is in what the gun does.
