The Rem Choke tube system is used on a number of Remington shotguns including the Model 870, Model 1100, and Model 11-87.
The choke tube is a constrictive piece that goes inside the bore of your shotgun in order to change the pattern and range. If you are using a shotgun shell with pellets in it, such as buckshot or birdshot, then a choke tube will help prevent the pellets from spreading at too wide of a range. As for those using slugs, a rifled choke tube will give this particular type of ammunition the best accuracy and range it could possibly have.

When it comes to steel shots with your shotgun, you need to have a more open choke instead of a full choke. The only way you should have a full choke is if it’s specifically approved for steel shots by the manufacturer. Otherwise, go with more open choke because it will allow the steel shot to safely exit the barrel without damaging your weapon. If your choke is specifically made for lead shots then you should never use a steel shot with your shotgun either. This information can usually be found on the manufacturer’s website or at the gun dealer where you purchased your weapon. You can also use improved cylinder chokes and modified chokes as well for steel shots. You don’t want the choke to be tighter than the modified choke or else it could damage the shotgun.
Here is new infogpraphic about shotgun choke tubes. I receive many questions about chokes and decided to make an infographic which explains basics.
Video about shotgun chokes:
A shotgun choke is found inside the bore of a shotgun barrel. It basically has a series of markings that helps shape the spread of the shot that is fired as it is coming out of the barrel. The specific choke you use determines the range and accuracy of the shot. Many choke models available have identification markings on the rim of each choke tube. That way the gun owner will know what type of choke is installed in the barrel without having to take it out.
2 new interesting chokes from Carlson’s company which is well known for shotgun owners. This company manufactures barrels for Remington 870.
I didn’t have a chance to test them, so if you have any info, please leave a comment.
What is the purpose of a choke in a shotgun?
The choke in a shotgun is designed to shape how the shot spreads after you pull the trigger. That way you can gain more accuracy with your shots as well as better range. The choke is placed in the bore of the shogun barrel, which is at the muzzle end. There are a two ways a choke gets installed into a shogun. The screw-in chokes, which are easily replaceable and there are also fixed chokes that integrated into the shogun barrel so that it is a part of the bore without being replaceable. So which ones are the best to use? Both are acceptable.
There was interesting and useful discussion about chokes on Remington 870 Forum.
