You should be able to tell by looking down the barrel and if it does have a choke it will be slotted to allow for a choke wrench. If not just stick your finger in the end and try to unscrew the choke. All while its unloaded of course. I would think that most modern shotguns have chokes but I could be wrong. Ive always had remingtons and benneli's
it's not necessary to have choke tubes in order to have a choked barrel....but that's a good way to figure it out...and the tubes themselves are stamped.
Could be Full Choke, Modified, Improved Modified, Cylinder etc. More often than not a shotgun will have some kind of choke and you can get a simple choke guage in order to tell how restricted the barrel has become.
Yes agree. Fixed choke will most likely be stamped on the reciever-end of the barrel, not the receiver itself, since it's the barrels that get swapped out or changed. Screw-in chokes are very apparent when in the barrel. But f taken out, you can feel for screw-in threading or see it by using a light. Verify gun unloaded first if the barrel is in the gun.
Almost all shotgun barrels have chokes. The amount of choke determines the spread of the shot pellets.
Older shotguns have the choke built into the barrel, and as has been stated there will be a choke "code" stambed on the chamber end of the barrel. I have a Miroku Over/Under that I bought new in 1970 that is choked Full over Modified that is stamped "+ "and "+-". I also have a Browning BT-99 trap gun that I bought new in the early 80's that has two barrels. One is 34" long and is full choked and is stamped "34*", The other is 32" long and choked improved modified that is stamped "32*-".
My skeet gun is a Browning Citori that has screw in "Invector" chokes. These chokes have the amount of choke stamped on the side and a notch or notches on the end of the choke so you can tell what the choke is without taking it out. For example, skeet 2 chokes have 5 notches, and as the chokes get tighter there are less notches down to full choke that has one notch.
I also have a Remington 870 with screw in "Rem" chokes. These chokes only have the amount of choke stamped on the side of the choke. You have to take the choke out to find out what choke it is.
They are all different. You have to know the manufacturer's code to know what the choke is.
Manufacture's Codes!!! Yeah they tend to be a problem translating, especially on European made firearms, but also on some American guns too. Chokes, year of proofing, year of manufacture, etc. Why can't all gun makers just make it simple and stamp "mod.choke" or "nitro-proofed 1982" etc? What's with all the dots, symbols, slashes, and alpha/numeric codes??
For many Belgian, Spanish, and Italian made guns there are charts available to translate the letter codes and determine the year the gun was nitro-proofed, it's a safe bet that is the same year it was manufactured too.
What does "gauge" mean anyway? As used here gauge means the number of round lead balls the same diameter as the inside of the barrel (aka the bore) that it would take to weigh one pound. It takes 12 lead balls the same diameter as a 12 gauge barrel to weigh a pound. The smaller 20 gauge would require 20 balls of that barrel diameter. The larger bore 12 gauge would require 12 lead balls of the bore diameter to weigh one pound.
In general the number of pellets in a shotgun shell...
