![]() Many people wonder whether it is really worth it, when they can cost 40 – 60 percent more than hollow or soft points. There is, however, a lot of conjecture around this bullet type, possibly due to the cost per bullet. However, the hole is covered by a cone-shaped piece of plastic that gives the aerodynamic benefits of a FMJ, giving it greater accuracy over longer distances. The hole at the tip is exaggerated, like the hollow point, which allows the bullet to expand on impact. A favourite round for big bore hunters with larger or dangerous game in their sights.īallistic tip – this is basically the upgrade to the soft point, and combines the benefits of the FMJ, the hollow tip and the soft point and then improves it. Soft point – combines the long range accuracy of a FMJ with the terminal ballistics of a hollow point by leaving a small, soft point of the lead core protruding from the front of the round. Testing your rifle and bullet choice at various distances is important to gain confidence with the tools. However, the hole also creates drag, which slows the bullet and can limit the overall accuracy for longer distance shooting. For this reason, they are a good choice for hunting. Hollow point – these bullets feature a hole at the tip that is designed to force the bullet to expand on impact and cause a bigger (more fatal) wound. FMJs do have a tendency to pinhole living targets, exiting the body leaving only a very small wound, so care should be taken if you are considering them for hunting. FMJs are cheap to produce and accurate over long distances, which makes them ideal ammunition for target shooting. Projectiles are generally constructed of a solid lead core covered in a copper jacket and come in several common variants, including:įull metal jacket (FMJ) – a lead bullet fully covered from base to tip in copper (which can either be pointed or rounded). This is the tip of the spear (so to speak), the part on the end of a cartridge that is expelled out of the barrel and that hits the target. Gunpowder burns rapidly when ignited, expanding to a gas that, together with the primer, forces the projectile down the barrel. Propellant (gunpowder)Ī chemical substance that consists of around 75 percent potassium nitrate (saltpeter), 15 percent charcoal, and 10 percent sulfur. Located in the base of the case, the primer contains a small, impact sensitive compound that, when struck by the firing pin, ignites the gunpowder and expels the projectile. Typically made of brass, copper, or steel (though other materials can also be used), the case acts as a container, holding all the other components together. This technique is beyond the skills of most hunters and shooters.Īll rifle ammunition is made up of these four basic components: This is because rimfire ammunition is generally limited to low-pressure loads, and would also require you to rebuild the casing. Most centre-fire ammunition is reloadable, however, rimfire ammunition is not normally reloaded. Rifle ammunition is either centre-fire (the firing pin hits the middle of the case) or rim-fire (the firing pin hits the edge of the case). Rifles use a cartridge containing a single projectile, also called a bullet, which comes in various sizes and weights. This is the metal housing that holds the working parts of the action. The firing pinĪ metal pin that strikes the primer on the bullet, causing ignition. The diameter of the bore determines the calibre of the rifle (however, for most ammunition, the calibre also refers to the outside diameter of the bullet used). The internal part of the barrel that the bullet travels through. There are some other internal parts not visible on the model above. Rifling is the process of cutting twists into the bore of the barrel, which makes the bullet spin and significantly improves accuracy (commonly known as the twist rate). During the mid-1600s, firearm manufacturers started to rifle the inside of the barrel. The barrel is the long metal tube that the bullet travels through. ![]() The stock acts like a handle and is generally composed of wood or a synthetic material. The action on many of the new rifles will often have rails to mount a scope. A bolt action rifle uses a bolt that acts as the door to your rifle and a lock for your breech. ![]() The action is the heart of your rifle and includes the moving parts that load, fire and eject the bullets. ![]() Sure, technology might have made some cool improvements to modern firearms, including the introduction of lightweight materials, and the terminology might have changed slightly, but all modern firearms have three basic groups of parts: action, stock and barrel. Rifles haven’t changed much since they were first invented.
