How to Measure a Shotgun Barrel for Length and Choke Width
How to Measure a Shotgun Barrel
A shotgun barrel is an essential part of any shotgun, and it’s important to know how to measure it correctly. Shotgun barrels are typically measured in inches, and the measurement is taken from the end of the chamber to the end of the muzzle. The choke is not included in the measurement.
There are a few different ways to measure a shotgun barrel. One way is to use a ruler or tape measure. Another way is to use a shotgun barrel micrometer. A shotgun barrel micrometer is a specialized tool that is designed specifically for measuring shotgun barrels.
Once you have measured your shotgun barrel, you can use the measurement to determine the correct choke for your shotgun. The choke is a device that is installed at the end of the barrel and it helps to control the spread of the shot. Different chokes are designed for different purposes, so it’s important to choose the correct choke for your shooting needs.
Here is a brief overview of the different types of chokes:
- Full choke: This is the most restrictive choke and it produces the smallest shot pattern. Full chokes are ideal for hunting waterfowl and other small game.
- Improved cylinder choke: This is a less restrictive choke than a full choke and it produces a larger shot pattern. Improved cylinder chokes are ideal for hunting upland game birds and rabbits.
- Skeet choke: This is a very open choke that produces a very wide shot pattern. Skeet chokes are ideal for shooting skeet and other clay target games.
- Turkey choke: This is a special type of choke that is designed for hunting turkeys. Turkey chokes produce a very tight shot pattern that is ideal for taking long shots at turkeys.
By understanding how to measure a shotgun barrel and by choosing the correct choke, you can improve your shooting accuracy and make sure that you’re getting the most out of your shotgun.

How do I measure a shotgun barrel?
To measure a shotgun barrel, you will need a ruler or tape measure.
1. Locate the muzzle end of the barrel. This is the end of the barrel that is pointed away from the gun when it is fired.
2. Place the ruler or tape measure at the muzzle end of the barrel.
3. Measure the length of the barrel from the muzzle end to the chamber. This measurement is typically given in inches.
What is the standard length for a shotgun barrel?
The standard length for a shotgun barrel is 28 inches. However, shotguns are available with barrels of various lengths, ranging from 18 inches to 36 inches. The length of the barrel will affect the shotgun’s performance, so it is important to choose the right length for your needs.
What is the difference between a smoothbore and a rifled shotgun barrel?
A smoothbore shotgun barrel has a smooth interior surface, while a rifled shotgun barrel has a series of spiral grooves cut into the interior surface. These grooves help to impart spin on the shot as it travels down the barrel, which improves accuracy.
How do I clean a shotgun barrel?
To clean a shotgun barrel, you will need a cleaning rod, a bore brush, solvent, and oil.
1. Remove the barrel from the shotgun.
2. Attach the cleaning rod to the bore brush.
3. Dip the bore brush in the solvent.
4. Insert the bore brush into the barrel and rotate it back and forth to clean the bore.
5. Repeat steps 3 and 4 until the bore is clean.
6. Dry the barrel with a cloth.
7. Apply a small amount of oil to the barrel.
8. Reassemble the shotgun.
What are the different types of shotgun chokes?
There are three main types of shotgun chokes:
- Cylinder choke: This type of choke has no constriction, and it allows all of the shot to spread out evenly as it exits the barrel. This type of choke is best for shooting at targets that are close-range.
- Improved cylinder choke: This type of choke has a slight constriction, and it helps to improve the accuracy of the shot at moderate ranges. This type of choke is a good choice for hunting small game.
- Full choke: This type of choke has a lot of constriction, and it produces a tight pattern of shot. This type of choke is best for shooting at targets that are long-range.
**How do I choose the right choke for my shotgun?
The type of choke that you choose will depend on the type of shooting that you will be doing. If you will be shooting at targets that are close-range, then you will want to choose a cylinder choke. If you will be shooting at targets that are moderate-range, then you will want to choose an improved cylinder choke. If you will be shooting at targets that are long-range, then you will want to choose a full choke.
