.260 Remington vs 6.5 Creedmoor

Well, title says it all. Thinking of building a custom rifle, and I am torn between these two cartridges.

I know there are pros and cons for both. Biggest pro for .260 Rem as far as i'm concerned is brass types. More options than 6.5 creedmoor. (I would use Lapua)

Biggest pro for 6.5 Creedmoor is the longer overall length possibility, with almost as much powder capacity. Biggest con is only Hornady makes brass for it. I don't dislike Hornady brass, but with only one supplier, leary about supply.

The intent for this rifle is F-Class Open. I plan to build from a Remington 700 action, Douglas barrel, at least 26", Nightforce 8-32x56. Stock, and small parts are still tbd.

Chime in with your thoughts, comments, etc. Not really considering other cartridges at this point, but throw them out with your reasons regardless.

I have a Savage LRP in .260 that will shoot 1/4moa with a cheap 10x40 Bushnell 3200 Elite and Warne 20moa base. They make the rifle in 6.5 CM also but like you I worried about the availabiity of brass. I like having the ability to use .243 .260 7mm-08 and .308 brass.

I'm having a custom rifle built on a savage model 10 action... It will be chambered in 6.5 Creedmoor.. Brass is a non-issue for me as I have a mountain of spent 22-250 cases laying around I can fire-form into 6.5 CM cases..

I went with 6XC.

Great exterior ballistics. Great bullet selection. Recoil nill. Brass can be formed from 22-250Rem.

I'd go for 260, the Lapua brass is a big plus for it.

There's another thread going on basically the same topic, I'd check that out for extra info.

Also check this out, http://demigodllc.com/articles/6.5-s...6.5-creedmoor/.
Zac smith has also commented on the other thread.

Have you thought about what bullet you want to use? This should be the deciding factor.

Given a good barrel, both should shoot about the same for group size. I have a .260 on a Winchester Model 70 action with a 26" Hart barrel. It is now shooting in the 3's with Hornady 129 & 140 gr. SSTs. The 140s are getting a little into the powder space.

The whole reason for the Hornady cartridge is to seat the longer Lapua 140s to the base of the neck and cram them into a short action. This may be important to you.

They are both great rounds and you will be happy with either.

This.
Comes down to your ability to drive the rifle. Ballistics are nearly identical, flip a coin.

Thanks everyone for the replies.

Zak Smith's article seems to favor 260, and that's what i'm thinking of going with right now.

My intended bullet is a 142 Gr Sierra Matchking, but I may also try the high BC Lapua 139 Gr.

I'd choose Creedmoor. Better shoulder angle for less brass flow leading to longer useable brass life.

Of course any of the 260 "Improved" versions fix the shoulder angle issue, but then you are into wildcat territory.

Have you considered using the Berger 140 gr Match Hybrid Target.
Just another option, quite a bit higher BC than the SMK.
