This is the outermost part of the ammunition and holds all the other components together. Most rifle casings are made of brass, which is a combination of copper and zinc. Brass is generally used for its durability and capacity for withstanding the high pressures of a miniature explosion without deforming.\u00a0<\/span><\/p><p>&nbsp;<\/p><figure id=\"attachment_4489\" aria-describedby=\"caption-attachment-4489\" style=\"width: 987px\" class=\"wp-caption aligncenter\"><img fetchpriority=\"high\" decoding=\"async\" class=\"wp-image-4489 size-full\" title=\"Basic Parts of Ammunition\" src=\"http:\/\/blog.tractoptics.com\/wp-content\/uploads\/2023\/10\/caseshornady.jpg\" alt=\"Basic Parts of Ammunition\" width=\"987\" height=\"551\" srcset=\"https:\/\/blog.tract-optics.co.za\/wp-content\/uploads\/sites\/4\/2023\/10\/caseshornady.jpg 987w, https:\/\/blog.tract-optics.co.za\/wp-content\/uploads\/sites\/4\/2023\/10\/caseshornady-300x167.jpg 300w, https:\/\/blog.tract-optics.co.za\/wp-content\/uploads\/sites\/4\/2023\/10\/caseshornady-768x429.jpg 768w, https:\/\/blog.tract-optics.co.za\/wp-content\/uploads\/sites\/4\/2023\/10\/caseshornady-537x300.jpg 537w, https:\/\/blog.tract-optics.co.za\/wp-content\/uploads\/sites\/4\/2023\/10\/caseshornady-150x84.jpg 150w\" sizes=\"(max-width: 987px) 100vw, 987px\" \/><figcaption id=\"caption-attachment-4489\" class=\"wp-caption-text\">Basic Parts of Ammunition<\/figcaption><\/figure><p><span style=\"font-weight: 400\">Steel, aluminum, and even plastic can also be used as alternatives to brass. But all serious shooters and reloaders will tell you that brass is the tried-and-true prime choice. Additionally, most <a title=\"Reloading Rifle Ammo for Beginners\" href=\"https:\/\/blog.tractoptics.com\/reloading-rifle-ammo-for-beginners\/\" data-wpil-monitor-id=\"1826\" target=\"_blank\" rel=\"noopener\">rifle casings are reusable and can be reloaded<\/a> multiple times before they need to be discarded.<\/span><\/p><p><span style=\"font-weight: 400\">The anatomy of a rifle casing consists of four parts: the base, body, neck, and mouth. The base holds the primer which ignites the gunpowder when struck by the firing pin. The body holds the gunpowder, while the neck holds the bullet in place and prevents it from falling out and dumping out the propellant. The mouth is the hole at the end of the neck where powder is poured in reloading and the bullet exits when the round is fired.<\/span><\/p><p>&nbsp;<\/p><p><iframe src=\"https:\/\/www.youtube.com\/embed\/ZzAJ0067w0s?si=BmxqQX2vaP4yfeYY\" width=\"560\" height=\"315\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p><p><a href=\"https:\/\/www.youtube.com\/watch?v=ZzAJ0067w0s\" target=\"_blank\" rel=\"noopener\">Pursuit of Accuracy<\/a> shows us <a href=\"https:\/\/blog.tract-optics.co.za\/how-to-get-the-most-out-of-your-binocular\/\">how to<\/a> test rimfire <a href=\"https:\/\/blog.tract-optics.co.za\/finding-the-right-ammo-for-your-rifle\/\">ammo<\/a>.<\/p><h2><\/h2><h2><span class=\"ez-toc-section\" id=\"The_Primer\"><\/span><b>The Primer<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2><p><span style=\"font-weight: 400\">The primer is a small, circular component located on the bottom of the casing.

Black powder creates a noticeable cloud that is difficult to see through until the smoke clears. Conversely, smokeless powder creates no cloud and is the type of powder used in all modern ammunition. This type of powder burns slowly and evenly, which helps to create consistent and accurate shots.<\/span><\/p><h2><span class=\"ez-toc-section\" id=\"The_Bullet\"><\/span><b>The Bullet<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2><p><span style=\"font-weight: 400\">Perhaps the most recognizable component of ammunition is the bullet. It is the projectile that is propelled out of the barrel and towards its intended target. The bullet is seated in the neck of the casing, and the casing is clamped down to hold the bullet in place.<\/span><\/p><p><span style=\"font-weight: 400\">Bullets are either \u201cexpanding\u201d or full metal jacket. Expanding rounds are cast with a lead core surrounded by a jacket, which is often made of copper. A small hole is usually left on the tip of the bullet so it will peel backward like a banana on impact.\u00a0<\/span><\/p><p>&nbsp;<\/p><figure id=\"attachment_4492\" aria-describedby=\"caption-attachment-4492\" style=\"width: 2560px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-4492 size-full\" title=\"Basic Parts of Ammunition\" src=\"http:\/\/blog.tractoptics.com\/wp-content\/uploads\/2023\/10\/Bullet.jpg\" alt=\"The basic parts of ammunition come down to four key components: the casing, primer, powder, and a bullet.\" width=\"2560\" height=\"1707\" srcset=\"https:\/\/blog.tract-optics.co.za\/wp-content\/uploads\/sites\/4\/2023\/10\/Bullet.jpg 2560w, https:\/\/blog.tract-optics.co.za\/wp-content\/uploads\/sites\/4\/2023\/10\/Bullet-300x200.jpg 300w, https:\/\/blog.tract-optics.co.za\/wp-content\/uploads\/sites\/4\/2023\/10\/Bullet-1024x683.jpg 1024w, https:\/\/blog.tract-optics.co.za\/wp-content\/uploads\/sites\/4\/2023\/10\/Bullet-768x512.jpg 768w, https:\/\/blog.tract-optics.co.za\/wp-content\/uploads\/sites\/4\/2023\/10\/Bullet-1536x1024.jpg 1536w, https:\/\/blog.tract-optics.co.za\/wp-content\/uploads\/sites\/4\/2023\/10\/Bullet-2048x1366.jpg 2048w, https:\/\/blog.tract-optics.co.za\/wp-content\/uploads\/sites\/4\/2023\/10\/Bullet-960x640.jpg 960w, https:\/\/blog.tract-optics.co.za\/wp-content\/uploads\/sites\/4\/2023\/10\/Bullet-450x300.jpg 450w, https:\/\/blog.tract-optics.co.za\/wp-content\/uploads\/sites\/4\/2023\/10\/Bullet-150x100.jpg 150w\" sizes=\"(max-width: 2560px) 100vw, 2560px\" \/><figcaption id=\"caption-attachment-4492\" class=\"wp-caption-text\">Basic Parts of Ammunition<\/figcaption><\/figure><p>&nbsp;<\/p><p><span style=\"font-weight: 400\">Bullet manufacturers can also achieve the same effect by leaving some of the lead tip exposed rather than completely coating it in copper. The peeling, or \u201cmushroom,\u201d will then tumble, creating a larger wound cavity in organic material. The larger wound channel leads to a faster and more ethical kill. Because of this, expanding rounds are more commonly used in <a title=\"Binoculars for Turkey Hunting\" href=\"https:\/\/blog.tractoptics.com\/binoculars-for-turkey-hunting\/\" data-wpil-monitor-id=\"723\" target=\"_blank\" rel=\"noopener\">hunting<\/a>.\u00a0<\/span><\/p><p><span style=\"font-weight: 400\">Higher-end rounds will also add a soft, plastic tip on the end of the bullet to increase aerodynamics in flight. On impact, the plastic tip falls away, and the exposed nose can mushroom in the same manner as un-tipped bullets.<\/span><\/p><p><span style=\"font-weight: 400\">Full metal jacket ammunition also uses a hard, gilded metal (also usually copper) around a soft, inner core, but none of the inner core is left exposed. The bullet is completely covered by the outer metal, hence the name, \u201cfull metal jacket.\u201d\u00a0<\/span><\/p><p><span style=\"font-weight: 400\">FMJ <a title=\"How to Better See Bullet Impacts\" href=\"https:\/\/blog.tractoptics.com\/how-to-better-see-bullet-impacts\/\" data-wpil-monitor-id=\"1570\" target=\"_blank\" rel=\"noopener\">bullets do not expand upon impact<\/a> and usually are less likely to tumble.
