Ergo, the 9x19mm cartridge<\/p>\n<p>The .38 Special, created back when ammo makers measured the neck, uses a .357-in diameter projectile but the cartridge case is .378 inches in diameter at the neck and base of the case. The .357 Magnum cartridge is named for the .357-in diameter projectile.<\/p>\n<p>Rifle cartridges largely have the same conventions; metric or English measurement of the diameter of the projectile. Some, such as 7x57mm Mauser, use the European measurement of \u201cbullet diameter\u201d x \u201ccase length.\u201d<\/p>\n<p>Gauge or bore of a shotgun is measured in a wholly funkier manner. How those are measured is how many lead spheres the same diameter of the barrel would make 1 lb of lead. In the case of 12 gauge, twelve of them. In the case of 20, twenty and so on. The only exception is .410 bore, which is the diameter of a slug fired from a .410 bore shell. The shell is actually 0.455 inches in diameter, which makes it a .45 caliber shotgun.<\/p>\n<p>So, now you can look at a cartridge name and get an idea as to how big it is.

However, if you insist on a big bullet, it\u2019s the easiest of the big boy calibers to shoot.<\/p>\n<p>Now onto rifles. Today\u2019s rifle shooter is frequently a tactical junkie, even though they probably have an office job. Ergo, the more common calibers and bullet sizes of yesteryear (long-action rounds like .270 Winchester, 7mm Remington Magnum and the best cartridge yet invented by man, .30-06) are almost unknown to them.<\/p>\n<p><figure id=\"attachment_488810\" aria-describedby=\"caption-attachment-488810\" style=\"width: 700px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/commons.wikimedia.org\/wiki\/File:An_Australian_soldier_loads_ammunition_into_a_magazine_before_a_match_during_the_2012_Australian_Army_Skills_at_Arms_Meeting_(AASAM)_May_7,_2012,_in_Puckapunyal,_Australia_120507-F-MQ656-399.jpg\"><img decoding=\"async\" loading=\"lazy\" class=\"wp-image-488810 size-large\" src=\"data:image\/svg+xml,%3Csvg%20xmlns=\" http:=\"\" alt=\"The Most Common Bullet Sizes And What They're Good For\" width=\"700\" height=\"466\" data-lazy-srcset=\"https:\/\/cdn0.thetruthaboutguns.com\/wp-content\/uploads\/2019\/03\/223-1-700x466.jpg 700w, https:\/\/www.thetruthaboutguns.com\/wp-content\/uploads\/2019\/03\/223-1-300x200.jpg 300w, https:\/\/www.thetruthaboutguns.com\/wp-content\/uploads\/2019\/03\/223-1-768x511.jpg 768w, https:\/\/www.thetruthaboutguns.com\/wp-content\/uploads\/2019\/03\/223-1-770x513.jpg 770w, https:\/\/www.thetruthaboutguns.com\/wp-content\/uploads\/2019\/03\/223-1-217x145.jpg 217w, https:\/\/www.thetruthaboutguns.com\/wp-content\/uploads\/2019\/03\/223-1-430x287.jpg 430w, https:\/\/www.thetruthaboutguns.com\/wp-content\/uploads\/2019\/03\/223-1-597x398.jpg 597w, https:\/\/www.thetruthaboutguns.com\/wp-content\/uploads\/2019\/03\/223-1.jpg 800w\" data-lazy-sizes=\"(max-width: 700px) 100vw, 700px\" data-lazy-src=\"https:\/\/cdn0.thetruthaboutguns.com\/wp-content\/uploads\/2019\/03\/223-1-700x466.jpg\"\/><noscript><img decoding=\"async\" loading=\"lazy\" class=\"wp-image-488810 size-large\" src=\"https:\/\/cdn0.thetruthaboutguns.com\/wp-content\/uploads\/2019\/03\/223-1-700x466.jpg\" alt=\"The Most Common Bullet Sizes And What They're Good For\" width=\"700\" height=\"466\" srcset=\"https:\/\/cdn0.thetruthaboutguns.com\/wp-content\/uploads\/2019\/03\/223-1-700x466.jpg 700w, https:\/\/www.thetruthaboutguns.com\/wp-content\/uploads\/2019\/03\/223-1-300x200.jpg 300w, https:\/\/www.thetruthaboutguns.com\/wp-content\/uploads\/2019\/03\/223-1-768x511.jpg 768w, https:\/\/www.thetruthaboutguns.com\/wp-content\/uploads\/2019\/03\/223-1-770x513.jpg 770w, https:\/\/www.thetruthaboutguns.com\/wp-content\/uploads\/2019\/03\/223-1-217x145.jpg 217w, https:\/\/www.thetruthaboutguns.com\/wp-content\/uploads\/2019\/03\/223-1-430x287.jpg 430w, https:\/\/www.thetruthaboutguns.com\/wp-content\/uploads\/2019\/03\/223-1-597x398.jpg 597w, https:\/\/www.thetruthaboutguns.com\/wp-content\/uploads\/2019\/03\/223-1.jpg 800w\" sizes=\"auto, (max-width: 700px) 100vw, 700px\"\/><\/noscript><\/a><figcaption id=\"caption-attachment-488810\" class=\"wp-caption-text\">TSgt Michael Holzworth [Public domain], <a href=\"https:\/\/commons.wikimedia.org\/wiki\/File:An_Australian_soldier_loads_ammunition_into_a_magazine_before_a_match_during_the_2012_Australian_Army_Skills_at_Arms_Meeting_(AASAM)_May_7,_2012,_in_Puckapunyal,_Australia_120507-F-MQ656-399.jpg\">via Wikimedia Commons<\/a><\/figcaption><\/figure>\n<p>Instead, the big deal is .223 Remington and its slightly hotter NATO counterpart, 5.56mm NATO.
