I've been running a Creedmoor for the past couple of years as my main long range comp rifle. In my mind, its a 260 done right. It is more effiecient, ie. less powder for the same velocities. However, the 260 damn sure has a place. Just different strokes for different folks. I also run 6.5x47 Lapua for long range comps. Ballistically, its a wash between the 3, they are all great.
 
i've been running the 6.5cm, like he said, its a 260 done right. they both have their place. the real question is should it be the 30-06 or the 308? that would let people have at her.:p
 
But...I like my .260....

And as for .308 vs .30-06, just go with 7.62x54 Rimmed! Highest kill count of any military cartridge, and the longest serving military cartridge in the world! And it's right in between .308 and .30-06!
 
I shoot both of them (6.5 CM & 260 Rem),as well as a 6.5-06. As long as there are reloading components available,none of the 6.5mm calibers are going to disappear anytime soon.
They are just too accurate,and perform better than most other calibers at most ranges.
 
Heck if I know. I have been asking buds which one to use for a long range rifle and opinions vary. You can make 6.5-08 brass from 308, more people are familiar with the 6.5-08, I guess it depends if you can find Creedmore brass.
 
Ok, here it is....

The 260 Remington(aka 6.5-08 A-Square) is simply the 308 necked down to 6.5 mm.

The Creedmore is the 308 necked down to 6.5mm and shortened 0.10".

This was done so that the higher weight/higher BC bullets would fit in the magazine, and not be pushed back so far into the powder space for the AR platform.

If you have the room in the magazine, and can get the throat cut long, the 260 will hold a couple of grains more powder.

However very seldom is best accuracy achieved at max velocity.
 
Creedmoor also has the 30 degree shoulder going for it. Brass doesnt grow too much in multiple firings. I have a reamer for a 260 that has .079 freebore and its good for running most of the 140s at mag length. Its when you get into the vld and hybrids that the length can be an issue and this is where the creedmoor is a little more forgiving. Still a wash as far as ballistics go.
 
In the AR platform, the 6.5CM is a better choice, in a bolt gun, the .260 is a better choice. By my count, there are at least a dozen 6.5 calibers available.
 
What advantage does the 260 have over the creedmoor in a bolt platform? I get that there is the lapua brass option. The lack of good 260 match ammo is something to consider. The hornady match ammo is good stuff. What else? I shoot long range comps every few weeks and i just dont see it.
 
I'd rather have a .250 Savage the Creedmore was based on. I settled for a .25-06 because of the difficulty finding rifles in .250 Savage.

Either way, any 6.5 cal offers great bullet selection. Take the 140 Berger Hybrid and point them and you have a G1 of .660. That's a pretty badass combo no matter what case is pushing them down range.
 
Everything has its place.

If you look elsewhere, that becomes more apparent.
Take 'intermediate' .30/.32 caliber cartridges, for example:
.30 WCF (on the "weak" end, but still respectable)
.30 Remington
.303 Savage
7.62x39mm
7.62x45mm
.300 Savage
.30-40 Krag / .303 British
7.5x54mm
.308 Win / .307 Win
7.5x55mm
7.62x54R / 7.62x53R (getting into "high powered" territory)

Every one of the above cartridges has its place in the food chain. In some cases, at certain points in history, circumstances dictated that one cartridge be chosen over another. So, some of them are obsolete or at least extremely unpopular today. But, that doesn't mean that an obsolete cartridge or less popular cartridge need to die, or should have died.

In some cases, such as 7.62x45mm and 7.62x39mm, the fate of a cartridge was determined by nothing more than politics, contrary to the actual performance of the cartridges.
When it came time for Com-Bloc nations to standardize their small arms..... There was more infrastructure already in place for 7.62x39mm, and the developers much more powerful, than the backing of 7.62x45mm. For the intent and purpose of the cartridge, the x45mm was arguably better. But, for the intent and purpose of political gain, guided by the the 800 lb Russian gorilla, the x39mm won the battle. The rest is history...


My brothers shoot .45 Colts.
I shoot .44 Mag.

My brothers shoot .45 Auto.
I shoot 9x19mm.

My brothers' 'big bores' are fairly modern bottleneck cartridges.
My big bores are .444 Marlins.


Different strokes for different folks.... ;)
 
Ahhhhh, but the 222 Rem Mag casing is still alive and used most often...

It's just necked down into what we now know as the 204 Ruger.


Back to the 6.5 thread....

My girlfriend has started going to the range with me more often. She really enjoys shooting my 7mm-08. "There is something satisfying shooting a steel turkey at 200-300 yards, hearing the PANG, and watching it fall over!!!"

She doesn't care for the recoil. Hence I've been looking at a Savage model 10 in the 260 Remington for her.

Ahhhh, ok - well maybe we need a .257 Creedmoor not a 6.5 creedmoor. :) And note that .223 rem (the round most similar to the .222 rem mag) still outsells .222 rem mag and .204 ruger combined, by a factor of many. So, although the .204 is a good round and deservedly here to stay, it's not the same thing at all as the "dead one" (.222 rem mag), being a completely different caliber which hits a sweet spot. But you're right that a lot of the brass is made from the original brass-making tooling for the .222 rem mag.

Sorry. The .303 British, which is still in everyday use today in various parts of the world, had been around longer. 1888 was the date of introduction. It's tied with the 8x57 which, in its original form, was introduced with the Model 1888 Commision rifle, and is also in everyday use in some parts of the world.
 
Dremel,

Well, along with the eventual plans to get her a 260Rem.

I've started my build for a 25 Souper. And am thinking/planning a build on the 6.5 Rem Mag. Would be a heavy barrel...

I wonder how the 350 casing differs from the 7mm Rem Mag???

More research!!!! lol ;)
