6.5 Creedmoor vs 6.5x55

My own take that admittedly is somewhat niche. Try to build a modern chassis rifle in 6.5x55mm where nearly everything has to be custom/special. 6.5x55 mm is too long to be short action compatible and sort of short for long action, chish is not nearly as standardized as short action chassis guns. When compared to building a chassis gun in 6.5 CM where everything is standard short action compatible. 6.5 CM fits in standard 308 AICS magazines, feeds through standard short action receivers, utilizing standard bolt faces. 6.5x55mm greatly reduces your compatible options building a chassis rifle.

I don't own either but I did recently build a chassis rifle in 6mm Creedmoor.
 
Well the point of the article which you seem to miss SharpDog is how similar in performance the two are. The 6.5 PRC is quite a bit more powerful and I’d like one very much. But the point of the article is apples to apples, not apples to oranges.

The performance is very similar but the platform it can be integrated in is not. 6.5 CM is compatible with a far greater variety of platforms than 6.5x55mm. Can't make a 6.5x55mm Short Action 700 but I can with 6.5 CM, same with an AR-10, M14, DPMS GenII (RIP), FAL etc, If it was a 308 Win it can become a 6.5 CM with a barrel change and minimal other changes.
 
And yes mcb yours is definitely a niche so why must you repeatedly put down the Swede? Your comment about the action length for a 6.5x55 has been stated by you on more than one occasion. You seem to obsess on the fact it was designed around an intermediate action. It’s a totally moot point because the 6.5x55 works great in a long action. And yes it’s true the 6.5x55 cannot be chambered in a short action but as has been stated before that is only an advantage for a specialized shooting environment. For most people the short vs long action argument doesn’t hold water.

Everything you say in this post is true and you have repeated it more than once. You refuse to get the point being made which is about the performance of the two cartridges, not the platforms they can be and are chambered in.

I have never put down the 6.5x55mm but too many of the pro 6.5x55mm want to discount or ignore that that 6.5 CM gives similar ballistics while being compatible with a much wider variety of common plateforms. Its not just niche chassis guns either. The wide variety of platform compatibility is partially why the 6.5 CM is currently so popular. It was easy for manufactures to integrate 6.5 CM into existing 308 based platforms both bolt guns and gas guns. Nearly all bolt gun manufactures' short action bolt gun now come in 6.5 CM, most AR-10 manufactures offer a 6.5 CM option. Springfield Armory is even offering it in their M1A. 6.5x55 is simply not as comparable across as many different common platforms. This is IMHO an important feature 6.5 CM has that 6.5x55mm does not.

I have repeatedly admitted in this and other threads that 6.5x55mm is the exterior ballistic equivalent if not slightly superior to 6.5 CM. I don't believe I have ever argues otherwise.
 
Because this:
Digging a bit deeper revealed that the new cartridge is too long for the short Remington Model 700 magazine. With an interior length of 2.840 inches, it restricts cartridge length to a maximum of 2.815 inches. SAAMI maximum for the 6.5 PRC is 2.955 inches, with the two Hornady factory loads measuring 2.950 inches. (snip) Everything considered, I became convinced that the long Model 700 action is the easiest way to squeeze top velocities from the 6.5 PRC while staying within SAAMI maximum chamber pressures.

LOL, looks to me like the point is how different these are ...

anyways I'm just posting what I personally would get now at this moment. I have no dog in the 6.5CM vs. Swede fight.

To each his/her own.
