From bolt actions to semi-automatics, the .308 is a versatile system. Below, we&#8217;ll talk about many aspects of the .308&#8217;s barrel length, including the significance of twist rate, velocities with various barrel lengths, and different uses for long and short barrels.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Gun owners enjoy the .308&#8217;s versatility as a high-powered, short-action round. It&#8217;s a cartridge that runs well in a variety of different rifle types, and various barrel lengths. When it comes to options, you can find a bullet type for just about any purpose. Availability for the cartridge is above average, and it&#8217;s more affordable than many comparable rounds which utilize the same bullet.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The best barrel length for a .308 depends on the firearm&#8217;s intended purpose. If you&#8217;re primarily a hunter chasing big game in the open range, you might consider a medium to a long-barreled rifle. However, if you&#8217;re using the .308 as an all-purpose or self-defense firearm, using a slightly shorter barrel will make the gun easier to handle.\u00a0<\/span><\/p>\n<h2>Best Barrel Length For 308?<\/h2>\n<div id=\"attachment_13068\" style=\"width: 1034px\" class=\"wp-caption alignnone\"><img decoding=\"async\" aria-describedby=\"caption-attachment-13068\" class=\"wp-image-13068 size-full\" title=\"comparing best barrel length for 308\" src=\"https:\/\/www.wideners.com\/blog\/wp-content\/uploads\/DSC8797-Web-1.jpg\" alt=\"a chart comparing best barrel length for 308\" width=\"1024\" height=\"683\" srcset=\"https:\/\/www.wideners.com\/blog\/wp-content\/uploads\/DSC8797-Web-1.jpg 1024w, https:\/\/www.wideners.com\/blog\/wp-content\/uploads\/DSC8797-Web-1-300x200.jpg 300w, https:\/\/www.wideners.com\/blog\/wp-content\/uploads\/DSC8797-Web-1-768x512.jpg 768w, https:\/\/www.wideners.com\/blog\/wp-content\/uploads\/DSC8797-Web-1-790x527.jpg 790w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><p id=\"caption-attachment-13068\" class=\"wp-caption-text\">Choose the barrel length that works best for your intended purpose and start training to reach your goals.<\/p><\/div>\n<p>There are three barrel-length categories we&#8217;ll be taking a look at in this article. Short barrels (10-14.5&#8243;), which are commonly found on pistols, or SBRs. Standard length barrels (16-18&#8243;) which are the most common lengths. As well as long barrels (20-26&#8243;), which are generally used for precision applications. While technically a &#8220;long barrel&#8221; is anything sixteen-plus inches, to make things simple, in this article we&#8217;ll acknowledge their length as twenty inches or greater.<\/p>\n<ul>\n<li><strong>Long: A barrel length of 20-26&#8243;<\/strong><\/li>\n<li><strong>Standard: A barrel length of 16-18&#8243;<\/strong><\/li>\n<li><strong>Short: A barrel length of 10-14.5&#8243;<\/strong><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">First, many hunters or long-range shooters have a bolt action <\/span><b>.308 with a barrel length of 20-26&#8243;.<\/b><span style=\"font-weight: 400;\"> The .308 competes with the 30-06 as a well-rounded hunting caliber. However, the .308 is also popular in semi-automatic rifles.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This leads us to our second category of barrel length, <\/span><b>.308s with a barrel length of 16-18&#8243;<\/b><span style=\"font-weight: 400;\">. These standard semi-autos are great for all-around use. They&#8217;re easy to carry, weigh less, and are easy to maneuver.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Finally, <\/span><b>the shortest barrels .308s range from 10-14.5&#8243;<\/b><span style=\"font-weight: 400;\"> and are commonly known as .308 <\/span><i><span style=\"font-weight: 400;\">pistols<\/span><\/i><span style=\"font-weight: 400;\">. These are ultra-portable and ideal for home or personal defense. Depending on how they are set up, they can also be classified as short-barreled rifles.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Each of these barrel-length categories has its strengths and weaknesses. Now, let&#8217;s talk about the common uses for these various .308 barrel lengths.\u00a0<\/span><\/p>\n<h3><b>.308 Barrel Lengths Compared<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Barrel length isn&#8217;t the only factor that affects accuracy, far from it in fact. A high-quality and carefully tuned barrel can produce consistent accuracy even if it&#8217;s slightly shorter. Barrels with the best accuracy have a good balance of stiffness and thickness in diameter.\u00a0 There are endless combinations of barrel lengths, material types, rifle styles, and ammunition that all contribute to a gun&#8217;s accuracy. \u00a0With that said, there are some industry-accepted norms to bear in mind. We&#8217;ll address some of those below.<\/span><\/p>\n<h4><b>Long 20-28&#8243; .308 Barrel Uses\u00a0<\/b><\/h4>\n<p><span style=\"font-weight: 400;\">Firearm owners use these barrels for longer-range shooting, usually 100 to 500-yards. The longer barrel gives the ammunition more velocity (see more about that in the next section) and will carry over long distances. These longer barrels are popular with competition shooters or big game hunters covering large areas.\u00a0<\/span><\/p>\n<h4><b>Standard 16-18&#8243; .308 Barrel Uses\u00a0<\/b><\/h4>\n<p><span style=\"font-weight: 400;\">A .308 with a 16-18&#8243; barrel provides sufficient accuracy from 100 to 300-yards, making it a solid all-purpose system. With this barrel length, you have a good home-defense option while still having the range for hunting.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The AR-10 with a standard barrel length is a popular platform for .308 calibers. If you&#8217;d like, you can read about the differences between the <\/span><a href=\"https:\/\/gearhunts.com\/ar10-vs-ar15\/\"><span style=\"font-weight: 400;\">AR-10 and the AR-15<\/span><\/a><span style=\"font-weight: 400;\">.<\/span><\/p>\n<h4><b>Short 10-14.5&#8243; .308 Barrel Uses\u00a0<\/b><\/h4>\n<p><span style=\"font-weight: 400;\">Any barrel below 16&#8243; can be classified as a pistol. These guns are made with ultimate portability and usability in mind. With a folding stock, some of these rifles may fit within a standard backpack.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">What&#8217;s the appeal of the short-barreled .308? It gives you the ability to carry a high-powered rifle cartridge in a convenient package. While you might lose accuracy and power at greater distances, the 10-14.5&#8243; .308 still offers a lot of use in the 100-200 yard plus range.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">How much power will you lose with a decreased barrel length? We&#8217;ll show you a table that outlines the relationship between barrel length and velocity in the next section.\u00a0<\/span><\/p>\n<h2>\u00a0<b>Barrel Length Velocity<\/b><\/h2>\n<div id=\"attachment_13011\" style=\"width: 1034px\" class=\"wp-caption alignnone\"><img decoding=\"async\" aria-describedby=\"caption-attachment-13011\" class=\"wp-image-13011 size-full\" title=\"federal american eagle 308 win ammo\" src=\"https:\/\/www.wideners.com\/blog\/wp-content\/uploads\/DSC8791-Web.jpg\" alt=\"a photo of federal american eagle 308 win ammo\" width=\"1024\" height=\"683\" srcset=\"https:\/\/www.wideners.com\/blog\/wp-content\/uploads\/DSC8791-Web.jpg 1024w, https:\/\/www.wideners.com\/blog\/wp-content\/uploads\/DSC8791-Web-300x200.jpg 300w, https:\/\/www.wideners.com\/blog\/wp-content\/uploads\/DSC8791-Web-768x512.jpg 768w, https:\/\/www.wideners.com\/blog\/wp-content\/uploads\/DSC8791-Web-790x527.jpg 790w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><p id=\"caption-attachment-13011\" class=\"wp-caption-text\">Federal&#8217;s American Eagle 150gr .308 Win FMJ ammo is a solid performer with an entry-level price.<\/p><\/div>\n<p><b>Comparison for 150-grain FMJ .308<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Velocity plays a huge role in the transfer of energy.

The twist rate represents how many inches of the barrel it takes to twist the round one full rotation.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">There&#8217;s a lot of advanced mathematics and physics behind twist rate; however, here are the bones of what you need to know: First, most .308 barrels have a twist rate of 1:12 &#8211; that means it takes twelve inches of barrel to twist the projectile one time. A 1:10 or 1:12 are the most common barrel twist rates for .308 rifles.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">A 1:12 twist rate is actually considered to be slow. However, if you&#8217;re shooting heavier grain ammunition, you may want a twist rate around 1:10. Why? Generally, the heavier bullets require a tighter spin to keep them stable. If you don&#8217;t get enough spin on the bullet, it could end up wobbling or <\/span><i><span style=\"font-weight: 400;\">yawing<\/span><\/i><span style=\"font-weight: 400;\">.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">To picture this, think about throwing a football. If you&#8217;re a quarterback, you probably know how to throw a tight spiral. With that said, if you don&#8217;t know how to throw a football, you could end up throwing a knuckleball, with the football tumbling all over. The same thing happens to bullets if you don&#8217;t match your barrel length, bullet grain, and twist rate.\u00a0<\/span><\/p>\n<h4><b>Barrel Materials &amp;\u00a0 Finish Options<\/b><\/h4>\n<p>Stainless steel dominates as the material of choice for barrel makers. 416-R stainless and 4150 carbon are the two most common steel types used in .308 barrel making. 416-R stainless has the highest-rated machinability and is ideal for high-accuracy applications. 4150 is often referred to as &#8220;Mil-Spec&#8221; steel and is ideal for high rate of fire applications.<\/p>\n<p><span style=\"font-weight: 400;\">You&#8217;ll find black oxide and Cerakote are common external barrel finishes. Black oxide is like dark-colored rust that protects the barrel from corrosion.\u00a0<\/span><span style=\"font-weight: 400;\">Cerakote is the name of a popular ceramic-based coating. Cerakote is a solid finish that protects the firearm while also giving you nearly endless options for colors and customization.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For the inside of the barrel, chrome lining is popular to prevent long-term corrosion resistance.

Don&#8217;t lose sleep at night worrying about the advanced mathematical formulas physicists use to tinker with .308 barrels. No matter which barrel length you choose, short, or long, there&#8217;s going to be a compromise. Choose the length that works best for your intended purpose and start training.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Focus on learning to operate your firearm safely and efficiently. Try out a few different types of ammo to see what runs the best in your gun. You&#8217;ll need practice ammo for your range days, and specific ammo for accomplishing your goals.
