If you own an AR-15, you\u2019ve probably fired thousands of .223 Remington rounds. You have likely done every possible activity with the cartridge, including varmint control, predator hunting, and target shooting.<\/p>\n

Maybe you want something different. Maybe you\u2019re looking to add more power or greater downrange potential. Perhaps you want something that can be used for deer hunting while maintaining the ease and versatility of the AR-15.<\/p>\n

One of the most popular alternatives is the 6.5 Grendel. Released in 2003, it has become almost (but not quite) as widespread as the ubiquitous .223 Remington. Whether you are purchasing your first AR-15 or want a new upper for your tried-and-true rifle, you must understand the performance capabilities of the 6.5 Grendel and compare these figures to the .223 Remington.<\/p>\n

Only then can you make the right choice for your next purchase.<\/p>\n

What\u2019s the Same Between 223 vs 6.5 Grendel<\/h3>\n

\"Firing<\/p>\n

While there are few similarities, these two rounds share a couple of traits. Most notably, they are both (primarily) fired from the AR-15 platform. This means you can enjoy all the features that make the AR rifle so popular, such as endless customizability, smooth shooting, semiautomatic performance, and trusted reliability.<\/p>\n

Physically, they are both 2.26 inches in overall length, but don\u2019t let that similarity fool you. As we will see, these are two very different rounds that have unique cases and bullets.<\/p>\n

Physical Differences<\/h3>\n

Other than the overall length, just about everything is different. The case of the 6.5 Grendel, which is shorter but fatter, has more total capacity. The .223 Remington case, by comparison, appears slim and long.<\/p>\n

The larger case gives the 6.5 Grendel a thicker, stockier appearance. This larger case allows the 6.5 Grendel to seat larger bullets as well. The .223 Remington has a standard bullet of 55 grains, with rounds ranging from about 36 to 77 grains. (Most are between 50 and 70 grains.) The 6.5 Grendel, however, starts at roughly 90 grains and goes up to about 130. This difference in grain weight will have a significant impact on performance.<\/p>\n

Finding and Buying the .223 and the 6.5 Grendel<\/h4>\n

You may assume 223 Remington ammo<\/a> is a more market-friendly option. You would be correct. But the 6.5 Grendel has a surprisingly large market acceptance; it\u2019s made by many of the top manufacturers in the ammo industry, and it\u2019s found on store shelves across the country. It may not be as widespread as the .223, but it\u2019s certainly not rare.<\/p>\n
