What is the difference between gauges in shotguns




















Give us a call or email and we can help you pick the right one. Because a 12 gauge shotgun shell has more volume than a 20 gauge shotgun shell, it fits more powder and bigger projectiles. This means you will get a harder-hitting shot at a greater effective distance with a 12 gauge than you will with a 20 gauge. In this scenario, a 12 gauge shotgun will have better overall performance than a 20 gauge.

In a scenario like this, you might get better performance from a 20 gauge shotgun. Performance is subjective and it has a lot of variables, which leads us to our next topic: applications. Because of this, there may or may not be some crossover. The bad news: you might need to buy more than one shotgun. The good news: you might need to buy more than one shotgun.

This is the same as it is with handgun or rifle hunting. At the end of the day, the goal is an ethical and humane hunt. Choose appropriately and responsibly. Plus, with the reduced energy of a 20 gauge versus a 12 gauge, you run a higher risk of wounding the animal instead of harvesting it.

Generally speaking, 12 gauge shotguns are the most popular for use in sporting clays. However, there are plenty of people who play the game with a 20 gauge shotgun, too. A lot of it really comes down to personal preference and situation. Or, maybe you prefer the softer recoil of a 20 gauge. Some prefer a smaller gauge because it adds an extra layer of challenge to the game.

This is, by far, the most complex topic on the list when trying to determine what gauge shotgun to use. As of late December As you can see from this count, there are tons of options for gauge shotgun. One of the leading retailers in the U.

The same is true for ammunition availability. At AmmunitionToGo. Total includes same shells in different-sized packages. For gauge shells, it kills me to admit, we have only Why is there such a drastic difference?

You can make the case it has less to do with overall performance the 16 gauge is certainly a strong performer , and more to do with industry options and consumer acceptance. In most cases, consumer use drives industry production, but it can go the other way.

Over the years, as consumers have started purchasing gauges as their all-around gun, manufacturers responded by creating more options, both in firearms and in ammo, for the 12, usually at the expense of other gauges. The result is that when new consumers enter the market for gun, they see that the gauge, because of general versatility and industry options, is often the best choice as an all-purpose shotgun.

Need a single shotgun for deer, upland bird, duck, and high-volume clay-pigeon shooting? The gauge is probably your best option. Consumers buy more gauge products, manufacturers create more options, and the process snowballs, making the 12 gauge the dominant bore among modern shotguns. You can see it among competition shooters, hunters, and even self-defense products. Because of the snowballing demand-production cycle, the gauge shotgun is king in virtually all field.

While the gauge,. A 12 gauge shotgun is easier to find a wider variety of ammo for than the somewhat rare 16 gauge shotgun. Price is heavily dependent on where you buy, how you buy, and obviously what you buy, but in general you will find that gauge ammunition is usually more affordable than gauge when the two products are similar.

Winchester makes Super-X ammunition with 1 ounces of 6 shot for both the 16 and the 12 gauge. Of course, prices can change over time. Shoulder fired weapons that fired projectiles weighing less than 1 pound used a closely related system. Large bore black powder rifles were named in this manner and this also is where the system for measuring shotgun gauges comes from. This is also true with a 10 gauge or 10 bore ball compared to a 12 gauge or 12 bore round ball. In short, the smaller the gauge of a shotgun, the larger the bore diameter.

This is why a 10 gauge shotgun has a larger diameter than a 12 gauge shotgun, which has a larger diameter than a 20 gauge shotgun, etc. A different way of saying the same thing would be to describe shotgun gauges in terms of the number of lead balls of a certain diameter necessary to weigh 1 pound.

There is one exception to this rule: the. If it were named like all the other popular shotgun bores, it would be approximately 67 gauge. Just reference the chart below for the nominal bore size of 10 gauge, 12 gauge, 16 gauge, 20 gauge, 28 gauge, and. Those numbers are great for making an overall comparison between the various shotgun gauges.

However, the actual diameter of the bore will sometimes vary. Remember: gauge size only describes the bore diameter of a shotgun. In addition to gauge, shotgun shells also come in varying lengths with different loads of powder, shot weight, shot size, and shot composition. For example, take a look at the photo below of a box of 20 gauge shotgun shells. Winchester markets this particular ammunition for upland bird hunting, sporting clays, skeet, and trap.

The shell lengths and gauges listed below are standardized by SAAMI and are therefore the most widely available and easy to find.

Sizes other than those listed below are sometimes available in limited numbers. Look on the barrel or chamber of your shotgun to determine the proper length shell it can use.

A shotgun with a longer chamber can generally safely use smaller shells, but the opposite is not true. Aside from shotgun slugs, shotgun shells are loaded with a large number of pellets. The exact number of pellets depends on their size and composition as well as the weight of pellets loaded into the shell. To determine the size of birdshot, just subtract the shot size from. This is not the case with other types of shot like BB and buckshot.

That being said, while there are exceptions, those other shot sizes larger than. Reference the table below to see the diameter of some of the most common shot sizes as well as the approximate number of lead pellets of that size that weigh one ounce.

As you can see, the number of individual pellets in an ounce decreases as the pellets increase in size. Some boxes of shotgun shells state the composition of the pellets. For instance, lead free, non-toxic shot is mandated for waterfowl hunting in North America. Of the materials commonly used to produce shot, lead is the most dense with a handful of exceptions, like tungsten. This means that a given number of individual lead pellets will weigh more than the same number of pellets of the same diameter made out of some other material.

A dram is a unit of mass from the British Avoirdupois weight system that still remains in varying degrees of use in some of the former colonies. Back in the days of black powder, drams were commonly used to measure the amount of black powder in a particular load. Most people probably know that there are 16 ounces in a pound. Well, there are 16 drams in an ounce. So therefore, there are drams in a pound. Additionally, many gun enthusiasts know that there are 7, grains in a pound.

This means that there are For that reason, companies are making the transition away from listing dram equivalents on shotgun shells and instead publishing the actual velocity of the load like on the boxes below. Lets be clear here: dram equivalents should only be used for a general comparison between two different shotgun loads. ONLY reload shells in accordance with the data supplied by a good reloading manual.

Of all the shotguns in the United States, 12 gauge guns are by far the most popular. The 20 gauge comes in second, followed by the 28 gauge and the. The 10 gauge and 16 gauge are much less common than the rest, but are by no means rare. The shot pattern of a shotgun gradually expands as range increases. This makes it easier to hit a target, particularly one that is moving, out to a certain range. Hunters can tighten up the shot spread to a certain extent by using a choke, which is a constriction on the muzzle of the shotgun.

However, there always eventually comes a point where the shot pattern is too spread out to guarantee a hit on an object that passes through the shot column. Additionally, the individual pellets all slow down as they leave the barrel. In general, heavier pellets retain more velocity at longer range and cause more damage than smaller and lighter pellets. However, increasing the size of shot results in fewer individual pellets.

So, increasing the shot size comes at the expense of a thinner shot pattern if the total shot weight remains the same. Certain shotguns pattern better with particular loads.
