What does a choke actually do??

sorry for this really random post but what exacally does a choke do on a gun as mine is fixed??? thats all i no lol

if varies the diameter of the end of the barrel thus meaning with a tighter choke it will give a tighter pattern.

it determines how wide or tight your shot pattern is as it leaves the barrel. less choke bigger spread.more choke tighter pattern.

As per the others have said,but dont worry too much about choking.As your gun is fixed choke just get used to where it shoots.

Choke gives the pellets a slight inward propulsion as they leave the barrel and thus controls the way in which the pellets spread, tighter chokes give a tighter pattern, no choke is called cylinder, then we have 'skeet', 1/4, sometimes 3/8, 1/2, 3/4 and full, choke does not really extend the usable range of the shotgun but rather gives more 'strikes'

 

or as i put it some weeks back with figures

 

Choke is a constriction at the muzzle end of the bore, by may be a few thousands of and inch, the effect of choke is to tighten the pattern of shot,

so say a true cylinder ( no constriction) will throw approx 40% of the shot into a 30 inch circle at 40 yards,

half choke will throw approx 60% /30 inch circle / 40 yards and

full choke will throw 75% / 30 inch circle / 40 yards

 

The idea is to have less holes in the pattern through which a clay or game whatever can fit through ensuring a clean kill

Use a pattern plate at the clay ground..Then you will see where the pattern is and the spread
