The parallel design results in reduced shot deformation, improved pattern uniformity and increased pattern density. In the year Beretta introduced the gauge Optima Bore barrel design into some of our competition shotguns. This design features a longer internal transition taper into the choke constriction, making the overall length of this tube longer than the original Mobil-Choke tube.

With the introduction of the model Xtrema shotguns in the Optima barrel configuration was added into the gauge line of field shotguns. In order to handle a higher volume of steel shot shells used in field hunting, the Optima-Choke tube was revised and manufactured with a thicker wall size. This revised choke tube was named the Optima-Choke Plus and featured the same Optima-Choke internal dimensions and performance but has a larger outside diameter and revised thread location.

As noted above under the Optima-Choke Plus section, the extended use of high performance steel and metal alloy non-toxic shot imparts considerable stresses. In the case of the Optima-Choke Plus part of the solution was to use a choke tube design offering a thicker choke tube wall to better resist these forces. This in turn results in a heavier, larger diameter barrel. To accomplish this Beretta engineers designed a choke system locating the threaded portion of tube a nominal 10 mm.

This effectively created an increase in wall thickness at the muzzle end of the choke tube where the greatest degree of choke constriction typically occurs and stresses are the highest without having to use the larger barrel contour.

Home Beretta Choke Tubes Guide. Beretta Choke Tubes Guide. Join Our Newsletter.Richard Atkins gets to grips with the unsung hero of modern shotgun design, the humble, though now ubiquitous clay shotgun choke.

This article seeks to cast light on what choke is and what it does. Clay shooters are fortunate to enjoy a vast choice of guns and equipment options today. Almost all new shotguns, whether they are for clay or game, over-and-under or semi-auto even some side-by-side guns now come with interchangeable clay shotgun chokes as standard.

A selection of chokes is usually supplied — maybe as few as three, but often as many as eight depending upon the maker and price.

How different this is to when I first got into clay shooting, when there were very few interchangeable choke guns and those available were mostly semi-automatic. Choke systems of that time tended to be bulky like the Cutts Compensator and so only suited single barrel guns. Despite their shortcomings those early examples opened a new world of choice to shooters and when the Remington semi-auto, with the Cutts device and interchangeable screw-in chokes, began to dominate in both Skeet and Trap disciplines in the USA, shooters took notice.

Naturally enough other gunmakers wanted a slice of the action. I remember this well because because I was already testing and writing about cartridges, guns and chokes, even back then. I was pleased to be asked by Winchester UK now a part of the Browning International empire to pattern test their guns with these chokes. They wanted photographs of examples of the patterns I got with the then new Winchester with Winchokes fitted; these photographs were then run across the bottom of their adverts for the guns to show the difference that the Winchokes could make.

They went on to become the first truly successful and readily available mass-market interchangeable chokes. Prior to the Winchoke guns I, like most other Sporting shooters, had to carry two guns — usually a Skeet gun and a Trap gun. Initially there were no true Sporters as we recognise them today, but they were soon developed and offered by all the major brands.

Of course, these new Sporters were invariably fitted with multi-chokes; the days of needing to own and carry two guns for Sporting clays were over! Suffice to say it was developed in the mid-to-late s and the identity of the original inventor remains uncertain.

WR Pape is often given the credit but others have possibly staked an earlier claim. He worked studiously to develop the choke, bore and forcing cone profiles and sizes with which he went on to win many prestigious shooting trials. These trials were organised by the shooting journals of the day.

Prize money was at stake, but no prize was more valuable than winning and Greener made his name by repeatedly doing so! Choke basically describes a constriction of the last part of the bore before the muzzle, to various dimensions.

This reduces the internal diameter by a fixed amount compared to the size of the bore concerned.

The latter point is important to understand, because a common error for newcomers is to buy a standard plug-type choke gauge to check their chokes with, and then ask questions on shooting forums as to why the marked sizes of their chokes do not match those on their gauge. It is therefore not a fixed bore size. However, the reduction in bore size is not the final arbiter that defines the degree of choke but more a useful indicator.

What defines each increment is the percentage of the pellets in the shot load that will, on average, arrive in a inch diameter circle at 40 yards.

These percentages were also arrived at when choke constriction was recognised and developed as a tool to improve shotgun performance. Those gun making maestros who fine-tuned choke boring in shotgun barrels also set out a workable set of percentages that provided a very useful reference.

Choke enables a shotgun to produce the most effective patterns for the task at hand, within the limits for which a shotgun is an appropriate tool — nothing more, nothing less. It is simply a means to give the shooter a more versatile and efficient gun. It provides a more effective pattern at a variety of ranges: not too tight for close range and not too loose at longer range.

The degrees of choke allow an efficient pattern to be achieved at every distance from close-in to maximum, making for greater versatility and effectiveness.Beretta produce a wide selection of chokes for their shotgun range. Please ensure you order the correct fitting for your gun. Introduced in the mid 's the Mobilchoke tube system was first available for the model SL over and under and later carried through virtually every model of fixed breech and semi-automatic shotgun.

The Mobilchoke system continues to be the mainstay of the series field grade over and under shotguns. The conical parallel design results in reduced shot deformation, improved pattern uniformity and increased pattern density.

Use of Optima-Choke HP choke tubes in barrels designed for use with Optima-Choke Tubes may result in catastrophic damage to your barrel and personal injury or death to the shooter or persons in the immediate vicinity!

Other Specifics. Each of the above choke tube types is designed for use with a specific type barrel and as such features different thread locations and external measurements, none can be interchanged with the other Beretta choke types. Within each of the three choke types we offer different variations of length and finish. The length variations available for each type is flush fit or extended choke tubes.

Most field shotguns are equipped with flush chokes. Sporting and skeet shotguns will be equipped with extended tubes. The Beretta factory may supply trap guns with either choke variation as determined.Introduced in the mid 's the Mobilchoke tube system was first available for the model SL over and under and later carried through virtually every model of fixed breech and semi-automatic shotgun.

Sporting and skeet shotguns will be equipped with extended tubes. The Beretta factory may supply trap guns with either choke variation as determined. Within the extended choke variations we offer two finishes. Since the extended chokes are exposed past the shotgun muzzle we offer choke tubes with a black non-reflective finish for hunters. It should be mentioned that two other choke types saw a limited use. Supplied with some and models shotguns was an early version of the Mobilchoke where the tube body was not threaded but smooth.

This type tube was dropped into the muzzle end of the barrel and secured by collar threaded onto the barrel muzzle.

This tube type is no longer available from Beretta.

The second type was offered on an early version of the DT shotgun made specifically for trap, this shotgun was known as the Vandalia model. These tubes are similar in size to the Optima choke flush tube but are not interchangeable with them. We still carry replacement tubes for this specific model. These codes do not indicate if the supplied choke is flush or extended.Shotgun choke can make all the difference to your shooting, so it's well worth following The Field's definitive guide.

Learn exactly what shotgun choke is, what it does, how it affects your shooting and which you should be using. Learn exactly what it is, which should be used for which gun and which quarry, how to measure it and, perhaps most crucially, when to stop tinkering. In an average cartridge there are approximately pellets, so how wide the shot pattern or how restricted is a matter than will make all the difference to your shooting.

There is no need to become neurotic about shotgun choke, even though some people do. What is most important is that regular misses in the field are rarely down to choke.

The cause is far more likely to be the direction the barrels are pointing. Choke is one of those things, like gunfit, that should be visited occasionally and put out of mind once an informed decision has been reached concerning what best suits your needs.

You should take your gun to a pattern plate or improvise one with paper or card sheets and a suitable frame and safe back-drop and shoot it at different ranges — 20yd, 30yd and 40yd — using the cartridge you prefer. You hope to see an even pattern without too many clusters, gaps or excessive central concentration. If there are holes a bird could fly through — a 5in circle test is sometimes applied — or if the pattern is obviously too tight, your shotgun and its chokes may be working against you.

Once you have tested with your usual ammunition, experiment with different cartridges. You might, for example, try to observe the terminal effects of switching between fibre and plastic wads the former often throw more open patterns or increasing pellet payload which may be an alternative to increasing choke.

If your gun has multi-chokes, try different tubes. The tools of the trade for measuring shotgun choke. Sportsmen develop strange prejudices concerning shotgun choke. My approach, and I happily admit to passing through the stage of confusion, is practical. I have discovered what works for me in different situations and now stick with it.

For general game-shooting, I like a bit of choke in the first barrel but not too much — it is the first few thou that makes the most obvious difference.

A slightly choked barrel is much more efficient than a true cylinder and inspires confidence, too. Many and bore game guns are over-choked for their task. Tight patterns may be a means to cleaner kills at longer range but they are an impediment at shorter distances because they demand more accuracy. If you are going out on the average driven day or walking-up, you do not need much choke in a bore.

The first few thou does make a real difference; thereafter the law of diminishing returns takes effect. Those who can see shot will confirm this. You can often observe what looks like a tennis ball-sized cluster of shot moving past the bird at short range. The initial idea was to create a workhorse without regard to aesthetics that would be as forgiving to shoot as possible on normal days.

It was based on an over-and-under because, though I love side-by sides, over-and-unders are usually easier to control and easier to point.

The Beretta action is supremely reliable, moreover, and the Essential, though a budget gun, had livelier barrels than the average because it dispensed with side ribs. The gun was a multi-choked model and this allowed for much experiment with shotgun chokes at the pattern plates and, later, in hides and on the shooting field. After some months of experiment, I determined that I had the most consistent first-shot success with something called a Seminole spreader choke.

This device is made in the USA. It might be described as a reverse choke: it has a section that extends from the muzzles and trumpets out to a greater size than the bore. The form of this section is conical. The concept of reverse constriction is not new.

My experience would seem to confirm this; the Seminole choke still works on clay birds 50yd out, yet it is very forgiving close in. They were not testing, but it really was quite difficult to miss with it. I have since lent it to friends in distress and they have always shot it better than other, more traditional weapons.Some obsess over it, some ignore it. What should you do? Ultimately, confidence and technique is what results in the most shot targets but using the correct choke in the right situation can give you an edge.

At the most basic level, a choke constricts the lead or lead alternative shot as it exits the barrel of the shotgun. This constriction makes the shot pattern tighter than what it would be if there was no choke used at all.

Well yes, and no…. Shotguns come in two formats — fixed choke and multi choke. It goes without saying that a multi choke gun will give you much more flexibility if you practise different types of shooting as you can swap and change the chokes as you wish.

With a fixed choke gun, you need to have physical alterations made to your barrels by a professional gunsmith. The choke tubes may be flush fitting or extended — these will physically look different when in the gun as shown in the illustration below. There are 6 common choke sizes. Confusingly, the names differ in the UK and US so both are detailed below.

All are in order from the least to the most choke so for example, Improved Cylinder in the UK corresponds with Skeet in the US as both are second on the list. Although the same name is used regardless of the bore of the gun, the actual constriction amount does differ. For example, on a 12 bore shotgun, the constriction to achieve full choke would be 0. The table below shows what the target percentage is across the most common choke sizes.

If you can, have a go on a pattern plate to make sure that your chokes and chosen cartridge are performing as expected based on the table above. Choke markings are used to identify different choke tubes. The marks can be bands of colour, stars or notches.

Unfortunately, different manufacturers mark their choke tubes in different ways — Beretta markings will be different to Browning which will be different to Perazzi. Beretta choke tube markings. Browning choke tube markings. Although we will go into detail for specific quarry and disciplines, the following can be used as a general guide:. Please note, the above and below all relate to lead shot only.

There are specific choke requirements for steel shot and it can be dangerous if you get it wrong. As the bird is travelling away from you, you want your most open choke to be on the barrel that fires first. With the tighter choke on the barrel that fires second, this will give you a bit more distance if a second shot is required.Choke choices for your shotgun.

Your shotgun was originally equipped with the Beretta Optima-Choke System. You should always verify that this choke system is on your shotgun before purchasing or installing new choke tubes. In the year Beretta introduced the gauge Optima Bore barrel design into some of our competition shotguns.

Barrels marked with the "OB" stamp will use the Optima-Choke system. This design features a longer internal transition taper into the choke constriction, making the overall length of this tube longer than the original Mobilchoke tube. Barrels that use the Optima-Choke will typically be marked OB immediately adjacent to the gauge marking. Optima-Choke choke tubes will be marked Optima-Choke. The start of the threaded portion of the Optima-Choke tube is located a nominal The length of the threaded portion is a nominal The major diameter of the choke tube thread is 20 mm.

Use of Optima-Choke HP choke tubes in barrels designed for use with Optima-Choke Tubes may result in catastrophic damage to your barrel and personal injury or death to the shooter or persons in the immediate vicinity! OptimaChoke Choices:. You can learn more about Beretta's choke systems here.

In order to verify the choke system on your shotgun, always check the barrel markings and the choke tubes that came with your shotgun, as the barrels on your shotgun may have been changed to a different choke system. Use of the incorrect choke tubes can cause series injury and damage your shotgun.
