Converting a rifle to fire a different cartridge in a different caliber and bore as what it initially was, means that the barrel of the rifle will also need to be changed. Because many competitive precision rifle shooters often shoot thousands of rounds per year both for practice and competitions, and they more often reach the end of their barrel life, whereby the <a href="/wiki/Rifling" title="Rifling">rifling</a> is worn down to a point where a rifle loses some of its <a href="/wiki/Accuracy" class="mw-redirect" title="Accuracy">accuracy</a>, the choice to make a caliber or cartridge change is often done at the same time as when a new rifle <a href="/wiki/Gun_barrel" title="Gun barrel">barrel</a> is fitted to the rifle by a <a href="/wiki/Gunsmith" title="Gunsmith">gunsmith</a>. There are a few important factors to consider when converting a rifle to a different caliber or cartridge. The action of the rifle should be long enough to contain the new cartridge, the magazine should also be able to hold the new cartridge, the bolt face should be the correct diameter<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> and the extractor the correct size to hold the head of the new cartridge. The most common of these caliber conversions on rifles, are usually done to change from a parent cartridge to a new cartridge based on it, like when converting a rifle to a <a href="/wiki/6.5mm_Creedmoor" title="6.5mm Creedmoor">6.5 mm Creedmoor</a> from a <a href="/wiki/.308_Winchester" title=".308 Winchester">308 Winchester</a> on which it is based. </p> <div class="mw-heading mw-heading2"><h2 id="Metric_and_US_customary">Metric and US customary</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Caliber&action=edit&section=3" title="Edit section: Metric and US customary"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1236090951" /><div role="note" class="hatnote navigation-not-searchable">Further information: <a href="/wiki/Metrication_in_the_United_States#Firearms" title="Metrication in the United States">Metrication in the United States § Firearms</a></div> <p>The following table lists some of the commonly used calibers where both metric and US customary units are used as equivalents.

See <a href="/wiki/Carronade#Ordnance" title="Carronade">Carronade#Ordnance</a>. </p><p>From about the mid-17th until the mid-19th century, the measurement of the bore of large gunpowder weapons was usually expressed as the weight of its iron shot in <a href="/wiki/Pound_(mass)" title="Pound (mass)">pounds</a>. Iron <a href="/wiki/Round_shot" title="Round shot">shot</a> was used as the standard reference because iron was the most common material used for artillery ammunition during that period, and solid spherical shot the most common form encountered. Artillery was classified thereby into standard categories, with the 3-pounder, 4-pounder, 6-pounder, 8-pounder, 9-pounder, 12-pounder, 18-pounder, 24-pounder, and 32-pounder being the most common sizes encountered, although larger, smaller and intermediate sizes existed. </p><p>In practice, though, significant variation occurred in the actual mass of the projectile for a given nominal shot weight. The country of manufacture is a significant consideration when determining bore diameters. For example, the French <a href="/wiki/Pound_(mass)#French_livre" title="Pound (mass)">livre</a>, until 1812, had a mass of 489.5 g (1.079 lb), whilst the contemporary English (<a href="/wiki/Avoirdupois" title="Avoirdupois">avoirdupois</a>) pound massed of approximately 454 g (1.001 lb). Thus, a French 32-pounder at the <a href="/wiki/Battle_of_Trafalgar" title="Battle of Trafalgar">Battle of Trafalgar</a> threw a shot with 1.138 kg (2.51 lb) more mass than an English 32-pounder. </p><p>Complicating matters further, muzzle-loaded weapons require a significant gap between the sides of the tube bore and the surface of the shot. This is necessary so the projectile may be inserted from the mouth to the base of the tube and seated securely adjacent the propellant charge with relative ease. The gap, called <a href="/wiki/Windage" title="Windage">windage</a>, increases the size of the bore with respect to the diameter of the shot somewhere between 10% and 20% depending upon the year the tube was cast and the <a href="/wiki/Foundry" title="Foundry">foundry</a> responsible. </p> <table class="wikitable"> <caption>English gun classes c. 1800<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources.
