Choke Tube Chart

Shotguns are a convenient tool for hunters and sports shooters as well. One of the major things that makes them more valuable is their choke tubes.

A shooter can improve firing accuracy or distance by developing the small tube in the cylinder’s front. Several choke tube types come with different qualities and purposes, like modified choke, cylinder choke, improved choke, and full choke.

Cylinder choke tubes come with the freest flight patterns and offer a viable firing range that is the most precise.

Open choke tubes are highly recommended to use for buckshot choke and birdshots at a short distance or range. Moreover, They deliver a broad pattern that kills targets at short ranges. The cylinder choke tube works fine at 15-25 yards.

Shotgun choke intends to control pattern diameter at the different yards. Don’t confuse it; look at the shotgun choke restriction table below to know more about the Diameter Difference between shotgun choke and bore.

With the shotgun choke, patterns are held together less tightly, so they are faster to produce.

These charts are only for general comparison, and these measurements are only for guide purposes. There are a lot of factors that matter how each choke will pattern. The measured internal bore is only one factor and always best to pattern the firearm. Choke type, brand, and shotshell define the optimal combination.

Some other chokes are specialized chokes to use in specific circumstances, like using a skeet choke during skeet shooting and a turkey choke during turkey hunting. Before selecting the choke, check out the patterning range to know the exact range and pattern of the particular choke you will choose.

Some other factors can affect how to choke tube fires, just like Ammunition types.

The constriction level inside a choke is the central part that should make every shooter know as some chokes come in different styles such as external and ported. And all these different styles of choke can affect a choke’s pattern, range, and sound.

The steel shot offers the shot in a tighter pattern than the lead shot, and the Rifled chokes will amazingly change the way of sabot slug travels.

So before choosing a choke, always consider all these aspects, size, and Choke Constriction Based on Distance to get the perfect shot. As mentioned earlier, the table shows steel yardage, lead yardage, shotgun choke restriction, and the average % of pellets with standard loads to make understanding easier for all shooters. For each type of ammunition, we recommend patterning the chokes and gun at different distances.

For a Tungsten, Steel shot, or other metal-alloy shot, never use a tighter choke than a Modified as professionals highly recommend it.
