    For one of my next builds I was thinking of either a 260 Remington or 6.5 Creedmore. From the research I have done both are flat shooting longer range cartridges.
    What are the pros and cons of these two rounds?

    This is a no brainer.;)
    If you are looking for a 'hobby' gun to shoot LONG range at paper the Creedmoor.
    If you want a light, hard hitting hunting rifle the 260.
    If you want a long range (300+ yds) but heavier hunting rifle I would go with the Creedmoor or a 6.5-06.:)

    Both seem to perform about the same as far as accuracy is concerned. The 260 has a slight ballistic edge. In the same general category, the 6.5x47 Lapua isn't bad either. GD

    The difference in 6.5 calibers is bullet weight. In any of them a 1:9.5 twist or 1:9 is best for heavier bullets. They are capable rounds.

    The 260 is the 308 Winchester necked down. The Creedmoor is slightly smaller with a sharper shoulder and longer neck. The 6.5x47 is shorter yet, sharper shouldered and features a small rifle primer pocket. The Lapua was designed aroung the 123 grain bullet while the others were designed around the 140.
    For bullets in the 139 to 144 grain class, an eight inch twist is required with many of the bullets.
    The easiest one to work with isprobably the 260 although the short neck is bothersome to some. I have built several "F" class rifles in this chambering and they have worked very well. I have not built ant Creedmoors but have built 6.5x55's and 6.5x47's and they have worked very well too. GD

    OK I goofed, My rifles are 1:7.5 twist. Hand loading for the 6.5's are the key.
    If you are hunting, you will need a heavier bullet. 120gr at 300 yards just don't have the penetration. 129gr are good out to 300 yards, 140gr are better.

    Close your eyes and point at one. Not much difference in the two. I would have went with the .260, but the rifle I settled on wasn't offered in the .260, so I went with the Creedmoor. I know you're building one, so that is not an issue for you. If you're hand loading for it, the .260 has a better selection of brass. If you're hand loading and wanting to feed from a magazine, the Creedmoor will feed from most magazines with the bullet seated at the lands. Both are outstanding cartridges. :)

    Both the 260 remington & the 6.5 creedmore are built on the .308 Win. case !.............

    The best solution of course is to have one of each.

    Sorry Tom,But the 260 Remington is based off the 308 Winchester case,the 6.5 Creedmoor is based off the 30 TC case not the 308 Winchester.

    Performance wise,Both calibers are almost equal at any range. The 260 has a slight case capacity advantage,but the 6.5 Creedmoor has a better case design neck angle,so the velocities are really close between the two.
    The real advantage the Creedmoor has over the 260 is being able to load the longer 140 grain bullets out to the barrel lands,and yet still be short enough to fit into a rifles magazine.

    You can really see the case difference here. The 6.5 Creedmoor is on the left,and the 260 Remington on the right.

    The Creedmoor works really well in the AR-10 style platforms where you are limited with a 2.810 COAL with the magazines,and even better with bolt actions where you can take advantage of the longer magazine lengths on some rifles.

    I shoot both calibers,but would only have the 6.5 Creedmoor if I could've bought an AR 10 style platform with the barrel style that I was wanting in that caliber.
    Instead,I bought the 260 Remington in the AR 10 style platform,and have been very happy with the performance of it also.

    Since I handload for everything I shoot,the brass for the 260 is easy to make,I resize 243 Winchester brass for my 260. If you want great brass,Nosler and Lapua also make 260 Remington brass,but you'll pay for it.
    The 6.5 Creedmoor was hampered for a while with soft brass from Hornady,the primer pockets would expand,and the brass was useless. Hornady has fixed that problem,and I have had very good luck with it. Nosler also started making brass for the Creedmoor,so that is another bonus. I have resized 22-250 brass for the Creedmoor,but haven't really tested it much for longevity,so I can't vouch for it yet.

    Both calibers are great for hunting or shooting long range,but I prefer the 6.5 Creedmoor over the 260 Remington,just my 2 cents.

    About 0.3-inch shorter than the .260. Now the 6.5 Creedmoor joins the mix. Changing from the ubiquitous .308 to one of these 6.5 mm calibers is a big improvement...........

    Believe what you want,but the 6.5 Creedmoor was designed off of the 30 TC case. If you don't believe it then why don't you call David Tubbs and ask him,or call the technical dept at Hornady.

    I'm not so sure about the 6.5x284... I keep reading two things, that it is in the .270 Winchester class, and that it eats barrels.

    The .270 is not known as a barrel eater.

    A 6.5-06 may be a better cartridge with ballistics directly comparable to the 6.5x284. - But not so hard on barrels.

    Between the 6.5 Creedmoor and the .260, the Creedmoor has more neck, handles longer bullets better due to shorter, tubbier case body. With lighter bullets up to 140 grain, there's allegedly not much difference between the two. I'd be happy with either one.

    Right out of Shotgun News..............
    Emary and the Hornady engineers went to work and by early 2007 had come up with a cartridge roughly based on the .308 body size, shooting a 6.5 mm bullet. The case has a 30-degree shoulder and a 0.370-inch neck. The case head is identical to .308 Winchester which makes it a shoe-in to any .308 action..............

    Shotgun News is a pretty good resource.

    Why not just look at the cartridge dimensions though, for a direct comparison?

    Shotgun News mentions the case head, but there's a lot more to a cartridge case than that. Body dimensions would tell us a lot more about what case the 6.5 Creedmoor derives from.

    From the pages of the Hornady reloading manual....[​IMG]

    I believe it says "based on the 30TC." This is from the folks that designed it.
