Shotgun slugs are dangerously over penetrative for most home defense scenarios. This article answers a reader’s question and discusses shotgun ballistics. My Account; Contact; Weekly Firearms Deliveries We ship direct to your door! Very clear general description of the stuff! It also has a MV of 1900 fps, and its velocity at 100 yards is given as 1615 fps. Even so, they are a stop gap alternative to a rifle, primarily useful where rifles are banned for political reasons. The violent acceleration from zero to initial velocity may deform many pellets. Resources, Law of Attraction Subconscious Mind Power. 20 gauge shells are commonly available in both 2 3/4″ and 3″ lengths. The sharp shoulder and flat front of the Brenneke mean that its external ballistics restrict it to short-range use as it does not retain its velocity well. A shotgun with a longer chamber can generally safely use smaller shells, but the opposite is not true. If possible, always use a rifle in preference to a slug gun for any kind of big game hunting. The cast rifling has little or no effect in spinning the projectile as it passes through the air. In addition to birdshot and buckshot loads, I always kept a pack of rifled slugs handy for my boat gun, a Mossberg 500 Mariner. at the muzzle, but only 926 ft. lbs. The less said about these small bore rifled slugs the better. When used in a police or military situation, shotgun slugs are often used against hard targets. Accuracy is apparently not quite as good as the best muzzleloaders, as Remington claims consistent 2 1/2" 5-shot groups at 100 yards. It is typically fired at a range of 4-6 in., aimed between the doorknob and door jamb, destroying the locking mechanism. Not only are these shotguns with rifled barrels technically rifles, they shoot like rifles. Our convenient site navigation and “blitzkrieg shipping” ensure your ammo shopping experience is a great one. Owners of these firearms usually have a specialist hand load the shells. Having said that, I believe the evidence supports #4 through OO buckshot for 12 gauge shotguns and either #4 or #3 buckshot for 20 gauge shotguns used in home or personal defense. Shotguns are also capable of firing a single projectile, called a ‘slug’. If I had to shoot a smoothbore 20 gauge slug gun, these are the loads I would use. Eventually the numbers change to letters until you reach the largest, which is called ‘buckshot’, a popular large-game round. As in all things firearms related, it is up to you to study the characteristics and match the right firearm and ammunition combination to match your own personal security considerations and needs. These distances only describe how far the shot column can travel. Break-open, pump, and semi-automatic shotguns share the same cycle of operations and functions as the rifles and pistols I covered in Internal Ballistics – Part I. Stick with 12 gauge Foster type slugs for deer hunting as the smaller gauges pack much less punch. While most shooters have heard the common gauges of 12, 20, 28, and .410, few know the origin of the term. As an Amazon Associate we earn from qualifying purchases. When purchasing shotgun ammo, just ignore the brass length. Saboted slugs will, when fired from a rifled barrel, produce near rifle-type accuracy. It would be difficult enough to characterize the trajectory of one sphere of a given mass and initial velocity, but the interaction of hundreds of spheres traveling together renders predictable flight to a matter of generalizations. Compared to practically any big game rifle bullet, rifled slugs are not very accurate. This is a short, blunt lead bullet that is solid in front and hollow in the rear, analogous to a badminton bird. If not, but the law allows the use of fully rifled "shotgun" barrels and saboted projectiles, that is what you should use. The more powerful 12 gauge slugs are only marginally better, and kick noticeably harder.

The use of slugs is best confined to single barrel shotguns, either single shot or repeaters. The rifled bore is designed primarily for the rifled slug and sabot rounds and produces the gyroscopic stability required to send the projectile to the intended target. In this product review, I, Sadly this focus on threat has many in both government and private security overlooking the most effective security strategy available to us, which is the engagement of. Thanks to the staff at “The Truth About Guns,” we can observe the effects of different shot types in ballistic gelatin. All rights reserved. Actually the ribs on the sides of the Brenneke and Forster style slugs do cause them to spin after they leave the barrel and help with stability. A high velocity rifle with a frangible bullet would be far safer in such an environment. Did I forget any shotgun ammo terms? If you recall from the Ballistics Series, the math and physics that govern rifle and pistol projectiles provided enough information to gain a sufficient understanding to accurately predict flight to target. Whilst it is generally accepted that shotgun slugs do not have to be fired through a cylinder barrel, it is not recommended that full choke barrels be used. Too-short of a forcing cone can exert undue stress on the lead shot and cause deformation while too-long of a forcing cone may not generate enough pressure for sufficient initial velocity. Thank you. A recoil velocity of over 10 fps is about the point at which shooting starts to get uncomfortable.

Fired from the same 12 gauge shotgun, we can see that these roughly 27 pellets cause a narrower but deeper permanent wound cavity and penetrate to about 14.5 inches. You say “A shotgun shell is cased in plastic with a brass base containing the firing pin.” ERROR = Not the firing pin (apt of the gun) but the Primer! Note: many of the variants tend to be at 100 to 125% of the base cost of comparable 12 gauge shotguns for some models because the 20 gauge shotgun does not sell through as many total units. Sighted to hit dead on at 50 yards, that slug is 4.8" low at 100 yards.

The following graphic demonstrates the spread of the shot pattern at different distances.

Would you add me to your list please? Skeet shooters engaging fast-crossing targets at close range desire a large quantity of small pellets, so they typically choose a #9 shot. Since the Remington catalog is still open in front of me, I will use their sabot slugs as representative of the type. 12-Gauge penetration tests in 10% gelatin. The 100 yard figures are 995 fps and 1074 ft. lbs. Therefore, I will focus the majority of this article on buckshot and birdshot. lbs., and the remaining energy at 100 yards is 1506 ft. lbs.

This is the forcing cone. These are for use only in fully rifled barrels.

The ME is given as 3086 ft. lbs. If we cannot distinguish between a firearm part and a primer, part of a shotshell, why trust any of this? Since the Brenneke slug is solid, rather than hollow like the Foster slug, the Brenneke will generally deform less on impact and provide deeper penetration. This is something you especially want to bear in mind if you keep a shotgun for home defense. Once only found in expensive custom shotguns, overbored barrels are now becoming common in mass-marketed guns. Rifled slugs are offered by most of the major ammunition makers in a variety of shotgun gauges, including 12, 16, 20, and .410 bore. It might be either stuck into a cavity at the bottom of the projectile or over the slug in external notches.

Saboted slugs are designed for the barrel rifling and use a shuttlecock method to keep them stable. If you recall, our discussion oninternal ballisticsfocused on the characteristics of the firearm, the cartridge, and the initial actions in the firing sequence that occur within the confines of the firearm. [4][5], The 10 gauge narrowly escaped obsolescence when steel and other nontoxic shot became required for waterfowl hunting, since the larger shell could hold the much larger sizes of low-density steel shot needed to reach the ranges necessary for waterfowl hunting. As such, they want a narrower and more “focused” shot column and choose a “tighter” choke.
The ammunition tested during this test eventThe ammunition tested during this test event is listed below:was provided by the customer and were as below: Gauge Shell Length Projectile 12 2.75 00 Buckshot 12 2.75 High Velocity Steel (BBB) 12 2.75 ITX-10 Duck #4 12 3.0 Nickel Plated Lead #5 12 2.75 1 ounce Thug Slug Primer – similar to rifles and pistols, the shot shell primer is a small metal cup that contains an explosive mixture that, when struck by the firing pin, sends a small flame through the base to ignite the propellant.
The Buckhammer lead slug itself is a short truncated cone, rather like a lead "Keith" style revolver bullet. 1 A shotgun with rifling at the muzzle end of the barrel.

The M82’s bullet is 14 times heavier, so it would tear you to shreds if you fired it out of a derringer. Saboted slugs (Figure 2.12) are sub-calibre missiles which have a discarding plastic collar surrounding the missile to bring it up to standard calibre. More important is the 100 yard retained energy figure of 1170 ft. lbs. Express Magnum Buckshot.
