on a single shot barrel you must remove the barrel and look at the flat side underneath the chamber to see the choke stamping.
I have a mercury 12 gauge magnum 3 inch chamber full& full choke`s made in liege -belgium.with ducks in grave and other in grave.
I would start my search at Smith and Wesson first.
A barrel with a full choke.
This project should be probable.I would have a competent gunsmith give you a quote for threading the barrel to except the Invector plus choke system.
If you see spiral grooves when looking down the barrel, then it is rifled.
I wouldn't. This could destroy the choke and expand the barrel.
If you mean a choke bored barrel, it designates the amount of constriction a shotgun barrel has.
Assuming that your Belguim made Browning auto-5,20 gauge magnum shotgun is in 98% condition.Iwould assess a value of 925 dollars for this model with a vent rib barrel that was made in 1970.If the gun rates a 95% condition then 850 dollars.
As long as the barrel choke is "NOT" a screw-in style choke tube............YES slugs can be shot through the barrel.
At the end of the barrel
choke of sears model 20 12 gage plain barrel shotgun has 3 stars on barrel
it should say right there on the receiver "made in Belgium"
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
It has a nickel steel barrel and is a 12 gauge with a mod choke. It has a nickel steel barrel and is a 12 gauge with a mod choke. It has a nickel steel barrel and is a 12 gauge with a mod choke.
A shotgun barrel with a cylinder bore choke.
The amount of constriction at the muzzle
No. A choke tube slips into and screws to the muzzle end of the barrel. It can only decrease the inside diameter.
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.
The fixed choke markings are denoted by * marks on the bottom of the barrel under the forearm assembly. 3 on the left barrel and 4 on the right. *** Modified choke **** Improved Cylinder
It is possible
Between 500 to 700 dollars depending on condition and location
It is possible to fire a shotgun without a choke, but it is highly not reccomended, and they don't cost that much If you select a barrel with no choke (cylinder) it will cause the pattern to be looser than for a barrel of a shotgun that has a tighter choke. The extreme is "full choke" which keeps a tight pattern out to the effective range. Full choke is typically used for waterfowl. A shotgun that is pressed into double duty (shot for small game and slugs for big game) would work well to have modified choke. Slugs have to be designed to fire through a full choke without blowing the barrel but you will certainly shorten the life of the barrel by firing slugs through a choked barrel. If you can afford an extra barrel, then use a cylinder (no choke) for slugs. Remington and other shotgun manufacturers have interchangeable choke tubes (see link) that allow you to screw in the appropriate choke for your quarry.
