@ Magnum
The choke holds the pattern of pellets into a more consistant circle at a given range.
The more constricted the choke, the more pellets will hit inside a 30" circle at a given distance.

IF ,your shotgun has screw in choke tubes, You should NOT fire you shotgun Without the Choke tube installed.
You will Foul the Fine threads on the inside of the barrel and might not be able to screw the choke in later, or even worse, you will CROSS THREAD the choke tube the mext time you try to install it in the Barrel.
This will ruin the Barrel.

SW Magnum, welcome to TGF. :greetings-waveyellow:

What chokes your shotgun has. Fixed (which are built in the barrel design) or removable? If your gun has fixed chokes than you have to live with it probably, there is no easy solution to this issue. If you have removable choke than you can install the chokes of your choice but as LAGS mentioned, the gun must not be fired without the chokes.

For details of various choke patterns, please go through various shotgun reviews in the Shotgun Reviews thread where members have posted the pattern results with different chokes.

regards

Seniors: Other than the reviews if one wants to install a choke for SD / HD purpose where the distance will not be more than 10m at the very max what choke type would you recommend.

LAGS: Also a basic question, when you say that The more constricted the choke, the more pellets will hit inside a 30" circle......... in simpler terms does this refer to the quick or delayed spread of the pellets ? If yes then will I be right if I said that the more constricted the choke, the time span or distance at which the pellets will fully spread out will be higher ? Pardon me if I sound stupid here. Just learning

A Choke does not SPREAD the pellets.
It keeps them held tighter together, so the number if pellets that hit in a 30" circle will be Greater at a Longer distance.

A tighter choke Does Not increase the distance that the pellets Actually Fly.
The tighter choke just makes the pellets fly closer together for the same distance, Thus making more pellets hit the target, at longer distances.

For Close range SD/HD an IC choke is Best.
It allows the pellets to spread on their own quicker and increase the chance of a HIT.
But for shooting DUCKS at greater distances, you would want a FULL choke to increase the number of pellets that hit the duck at a greater range.

Great discussion,
Usually we find five chokes with a new shotgun,(F,C,IC,M,IM)
Some one please explain which choke is tighter than which,
I mean how can we categorise them ?
And which choke is right for slugs ?

@Mian Jee
In simple words, choke is the constriction of a shotgun barrel near muzzle. It is therefore the difference in true bore diameter of a shotgun barrel and the internal diameter of the tightest portion of the choke, measured in 1/1000 of an inch. Each subsequent constriction is .005 inches apart and is given a name for identification like skeet, improved cylinder, modified, improved modified, full, extra full, turkey etc.

I think it is too confusing. Ok, standard bore diameter of a 12 gauge barrel is .730". The cyliner choke means the same diameter as the true bore, ie, .730". This means no constriction has been applied. Next choke which is Skeet is .005" tighter than the true bore, ie, .725". Next choke which is named Improved Cylinder or IC is another .005" tighter, ie, .720". And so on.................... Please see the table given below which has been devised by George Trulock, the renowned choke expert and manufacturer.

Image

At a given distance, the pattern would be widest with Cylinder Choke, would start shrinking with every subsequent choke and would be smallest with Turkey chokes. A shotgunner uses different types of chokes from different distances for different types of game / applications. If one is expecting to shoot at smaller distances than a cylinder or IC choke would suffice as it will make wider patterns as compared to tighter chokes at short distances. A long distance, the pattern of cylinder, Skeet or IC chokes would become too wide and would in fact dissipate, not leaving any worthwhile effect on the target. That is where one would need a tighter constriction / choke like full / extra full / turkey. You may go through the table and ask further questions, if any. :)

Thanks everyone for the warm welcome!

KBW,
I do not own a shotgun, but I have never heard about chokes for shotguns and decided to ask everyone here about them. :D

What are the gun laws in Singapore ? Can anyone own a handgun or are they only limited to rifles and shotguns ?

Guns laws here are strict. No civilians is to be in possession of guns at any time.
However, there is a gun club here.
But, that is as far as guns go in Singapore.

And, what this means would be that I've never held a gun in my life. :(

Referring back to the spread pattern choke chart as posted by MJ earlier, I was wondering that in a pump action 12G shotgun what kind / type of fixed choke is present ?

Sir, it will be one of the constriction which is given in the table above. Please check in you gun manual which constriction has been provided as fixed choke.

Your short Barrel if it does not have screw in chokes, will have it Stamped into the Barrel on the Left side back by the chamber.
Something like Cyl. IC, MOD ,Or Full

I coundn't see a pic of your Barrel on the left side Just above the slide or Foregrip.
This isnt the best picture but all My Mossy barrels are marked in the same spot on the Left side of the Barrel along with the length of shells it is chambered for.

I hilited my stamping in Red to try and make it easier to see.
