How does shotgun choke work

As a general principle, multi-chokes should have their threaded sections very lightly greased with something similar to Vaseline before they are screwed home. Check that your chokes are screwed home fully before use and repeat this check after and periodically during use. Chokes should be cleaned occasionally by immersion in petrol or a similar solvent.

Pay particular attention to the threads and make sure that foreign bodies such as grit are removed before installing the chokes again. Always discard a damaged shotgun choke tube. It is vital to use a pattern plate to determine what combination of choke works for you. The smaller the shot size, the more pellets there are to the ounce: No. The only way to increase pattern density is to tighten up the choke, which is not good for the average yard shot, or increase the weight of shot in a cartridge, which generates more felt perceived recoil.

Choke is a constriction of a few thousandths of an inch in the last two or three inches of a barrel. On a bore, full choke is a constriction of 40 thousandths of an inch, half-choke 20 thousandths of an inch, quarter-choke 10 thousandths of an inch and improved choke around five thousandths of an inch. The effect of choke is to squeeze the shot column as it is leaving the barrel and control the rate of spread. Using a fibre or plastic wad will also affect the pattern density.

Generally, a plastic wad will give a tighter pattern than a fibre wad. As conscientious, environmentally-concerned shooters, we should avoid using plastic wads however. Good stance, gun fit and technique are as important as the right chokes. This dates back to the days of muzzle-loaders, when game was walked- up over pointers. The first shot at a departing target would be the closer shot. With the advent of breechloaders and driven shooting, this remains unchanged, yet the first shot should be further away and the second directly overhead.

Generally, the tighter the constriction on the choke tube, the lower the notch count on the front. Modified chokes normally have three notches while a full choke would only have one. The number of notches can vary between manufacturers, so it is always important to double-check which choke tube you have before installing in your firearm.

Additional Information: In addition to the 4 most common chokes, there are other more specialized chokes. These are used in specific circumstances like using a turkey choke while turkey hunting or a skeet choke while skeet shooting.

There are many options when it comes to picking a choke and each one will pattern differently. Before taking a choke on a hunt, take the time to visit a patterning range and figure out the range and pattern of your particular choke.

Ammunition types can change how a choke tube fires as well. Steel shot fires in a significantly tighter pattern than lead shot. Rifled chokes will change how a sabot slug travels. A shooter must be aware of the level of constriction inside a choke, but chokes also come in a variety of styles like ported and external.

These additional styles can also affect a shot's sound, range, or pattern. Some chokes are designed specifically for steel shot and all chokes are designed to fit specific makes and models of firearms.

This was just the start! They proved it too! What are chokes for hunting and competition shotguns? Full chokes These are the most extreme chokes available for smoothbore shotguns. A choke limits the dispersion of the pellets.

Delay decreases, as the pellets have a higher residual velocity at long ranges. By changing one thing at a time. Start with the cartridges , trying different types.

In general felt wads, especially in a roll crimped case, produce a more generous spread. But the benefits will be hugely rewarding!
