They grow in strength. The 3" magnum implies you may use shotgun shells up to three inches long, and I believe you would be comfortable utilizing black power with [a standard charge or a magnum charge].
This length can be found in magnums, however most of the time it is merely regular loads. Other 12-gauge shell lengths include the 3-inch shotshell and the new 3-inch shotshell. These are strong shells that are employed in long-range field applications, such as hunting turkeys, geese, and ducks. Anything beyond that amount is referred to as a magnum.
Magnum shotshells have more gunpowder than regular loads, which gives them more "knock-down" power, although muzzle velocity is only one factor. The term "magnum" refers to the amount of gunpowder included in a shotgun shell, which is often the largest amount feasible for the shell size. Shells labeled as "magnums" can contain from 3 to 4 ounces of powder.
These shells are designed for large game such as bears, wolves, and large birds. They produce large wounds when fired at close range.
Magazines for semi-automatic shotguns usually hold 12 shells. For long-action guns, magazines can hold up to 20 shells.
The ability to fire multiple shots without reloading is important for hunters who want to put as much lead into their prey as possible. Shooting from longer ranges requires more accuracy with each shot, which means better sights are needed on all firearms used for hunting large game.
Also, hunters who pursue large game often use telescopes or other devices that enable them to see distant targets. Being able to shoot accurately across long distances requires special ammunition with high ballistic coefficients (the percentage of surface area that is exposed when a bullet is fired). These cartridges tend to be heavy for their size; the 7mm Remington Magnum is an example of a popular cartridge designed for long-range shooting.
The name "magnum" on shotguns merely denotes that the shell in question contains a heavier than regular shot charge. This occasionally necessitates the use of a longer case, although most of the time the magnum payload of shot is carried in a case that is no longer than ordinary length. The term is not standardized and can be found on shots from various manufacturers using different definitions. For example, some will only accept shells with cases measuring 9.5 inches or less, while others will accept cases up to 10.5 inches long.
The term "magnum load" is used by hunters to describe a shotgun shell containing one ounce or more of shot. In other words, a 12-gauge pump gun cannot handle shells containing more than 1/2 oz. Of shot. The limit for a side-by-side is usually given as 3/4 oz. , but can be as high as 1 oz.
There are several types of magnum loads, including:
1 Standard Magnum Shells - These shells are available in all standard sizes and are designed to fit standard size pump guns. They generally contain 1-3/4 ounces of shot.
2 Extended Magnum Shells - Like standard shells, these shells are available in all standard sizes, but they are designed to fit extended size pump guns. They tend to contain 1-1/8 ounces of shot.
The combination of short action length and efficient powder burning allows you to possess a rifle with magnum power but is significantly shorter, lighter, and more portable than a typical magnum rifle. Short magnums were originally designed for use with low-power ammunition such as.22 Long Rifle,.17 HMR, and.15 WMR, but modern reproductions are available in 7.62 x 51 RAL and other calibers.
Short magnums use large diameter bullets to produce greater ballistic coefficient (the measure of projectile efficiency) at the expense of weight and size. The reduced mass of short magnums makes them ideal for hunting small game and for shooters who prefer a compact weapon system.
While traditional magnums were designed to handle heavy bullet weights, short magnums were instead optimized for speed. That means that while traditional magnums can hold more energy per unit mass, they are also capable of handling much heavier projectiles. For example, it is possible to shoot a 250-grain bullet at over 1,000 fps from a short Magnum.
Since short magnums use smaller diameter barrels than traditional magnums, they are less likely to suffer from barrel wear. This means that they will usually require replacement sooner rather than later if you're looking for a long-term solution to your shooting needs.
Introduction The size, velocity, and energy dissipated are what distinguishes a conventional gun bullet from a magnum one. Magnum gun round cartridges are larger, have greater speed and power, and exude more strength than standard gun rounds. Their larger diameter produces higher muzzle velocities and more penetrating power.
There are three major types of rifle ammunition: ball, slug, and shot. Each type is used for a different purpose. Ball ammo consists of spherical bullets that fit into the chamber of your firearm. When fired, they create a loud report and go straight through your target. Slugs are long, heavy projectiles made of lead or steel that can be used to kill large animals. They tend to travel faster than ball ammo and are designed to remain inside their victim after impact. Shot is an obsolete term for small metal balls used as ammunition for firearms before the advent of modern bullets.
Ball ammo comes in several sizes, based on diameter. Winchester Magnum, 8mm, 9mm, 10mm, 12mm, 15mm, and 17mm. All ball ammo must meet specifications set by law enforcement agencies for maximum penetration. This is called "jacketing" the round and refers to the addition of material to the base of the bullet to increase its weight and prevent it from being too lightweight.
