The 6.5 Creedmoor VS 223 are both popular rounds. The .223 Rem has been a household name for over fifty years, while the 6.5 Creedmoor is a rising star. But how do these rounds overlap, and how do they differ? If you could only choose one, which would it be?\u00a0<\/span><\/p>\n

The 6.5 Creedmoor and the .223 are like Floyd Mayweather and Mike Tyson \u2013 both skilled at their craft but not in the same weight class. However, even though these rounds aren’t in direct competition with each other, they do have some overlap in their uses. And indeed, there are benefits and drawbacks to both the .223 and the 6.5 Creedmoor.<\/span><\/p>\n

Let’s discuss the differences between these venerable rounds, what tasks each excels at, and why you might choose one over the other.\u00a0<\/span><\/p>\n

History of the 6.5 Creedmoor and the .223 Remington\u00a0\u00a0<\/b><\/h2>\n

The 6.5 Creedmoor came about around 2007. What was the 6.5 Creedmoor all about? One of the lead designers, <\/span>Dave Emary,<\/span><\/a> stated their goal was to create a long-range competition round. And indeed, most agree that the 6.5 Creedmoor achieved that goal.<\/span><\/p>\n

Where does the name “Creedmoor” come from? That was a nod to <\/span>Creedmoor Sports<\/span><\/a> and<\/span> the original Creedmoor shooting matches. While competition shooting was the original road for the 6.5 Creedmoor, the long-distance accuracy and stable bullet quickly became popular as a hunting round, primarily for medium-large game.\u00a0<\/span><\/p>\n

We mentioned that the 6.5 Creedmoor is a new round, but that’s not by any means to say that it’s the first “6.5” round. The 6.5 Creedmoor is a new iteration of the<\/span> “6.5 Swede,”<\/span><\/a> which was first created and used in 1891. Historically, the 6.5 rounds of any kind have been more popular in Europe, but that’s starting to change.\u00a0<\/span><\/p>\n

.223 Remington Overview<\/b><\/h2>\n

The .223 is older than the 6.5 Creedmoor, developed in the early 1960s. The .223 is closely related to the 5.56 NATO (which the military adopted for the M16 rifle and has been widely used ever since). While the 6.5 Creedmoor was developed as a competition round and then drifted into the hunting space, the .223 was designed more as a combat round that proved popular on the civilian market.\u00a0<\/span><\/p>\n

Let’s break down some of the numbers on these rounds so you can form a more concrete picture of what they can and can’t do.\u00a0<\/span><\/p>\n

In this section, we’ll take some time and look at the raw numbers on these two cartridges. As we’ve said, these rounds aren’t necessarily in the same class – this section will show you some numbers that explain why. Later we’ll discuss some ballistics for the 6.5 Creedmoor and the .223.\u00a0<\/span><\/p>\n
