What is a choke air rifle barrel?
A choked barrel is one in which there’s a reduction in the diameter of the bore near the muzzle. Someone likened it to the FX Smooth Twist barrel that’s rifled only at the end of the barrel, but it isn’t the same. A choked rifle barrel squeezes the bullet or pellet slightly just before it leaves the muzzle.
What is a shotgun choke?
The choke of a shotgun determines shot string only. It has no bearing on shot speed (velocity) or distance (range). That is, the choke does not alter the shotgun’s power—it just controls how tight or spread out the pellets will be at a specific distance. Cylinder choke is an unconstricted barrel.
Can you put a choke on a double barrel shotgun?
Screw-in chokes add huge versatility to shotguns and can be used in both single and double barreled guns. The older fixed choke barrels pattern much better because the choke starts about 6~8″ from the muzzle, rather than 2~3″ for a screw-in or Poly-Choke.
Why does a shotgun have a choke on the barrel?
Most shooters know that shotguns are choked, and they understand why. A choke keeps the shot from spreading as quickly as it would without a choke. Shotguns have several specific kinds of chokes that make the pattern they project contain a certain shot density at a given distance from the muzzle.
Which is the correct definition of a choke?
In firearms, a choke is a tapered constriction of a gun barrel at the muzzle end.
How is a choke barrel different from a smooth twist barrel?
Someone likened it to the FX Smooth Twist barrel that’s rifled only at the end of the barrel, but it isn’t the same. The Smooth Twist barrel has a constriction — the rising of the rifled lands. But in a choked barrel, the entire bore gets smaller. I don’t know if the Smooth Twist barrel is also choked; but if it is, that’s a separate thing.
How big is the choke on a 12 bore shotgun?
For example, on a 12 bore shotgun, the constriction to achieve full choke would be 0.040″ whereas on a 20 bore shotgun, it would be 0.027″. If you’re looking to learn more about the specific sizes in more detail, see our article improved cylinder vs modified choke.
