Zak Smith did. Here is an excerpt of his comparison of 260, 6.5 Creedmoor, and 6.5x47.
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: Zak Smith</div><div class="ubbcode-body">I'm still shooting my original (2006) .260 Remington barrel on my AI-AW 2.0, and it's still performing great. I used the same gun, barrel, and cartridge to win matches in late Summer 2009 that I used in 2006 to win the Steel Safari. I gave back the Tubb gun in 6.5 Creedmoor (and its owner got rid of the 6.5 Creedmoor barrel), and I sold the 6.5x47 Lapua barrel for my AI-AW.
In the end, neither of these new upstart cartridges did anything for me that the .260 didn't. With the new Reloder 17 powder, I am now launching the 139gr Scenar at just over 2900 fps from my 26" Rock Creek barrel. Some of my associates are shooting a load using this powder at 2980 fps; however, the large firing pin hole in my AI-AW does not allow this.</div></div>

Re: Any 6.5x47L shooters, change over to 260?
Interesting, well my bbl is fixed at 23" so would I expect 2700-2800 w/139-142s w/RL17 in a 260?
Loved the idea of a 47, but NOT loving proprietary brass at increasing inflation....thanks for the reply.

Re: Any 6.5x47L shooters, change over to 260?
I'm shooting a 6.5x47 and according to QL the two are usually within about 20-50 fps apart as far as velocity given the same powder and tube length and pressures in relation to max that I would be willing to shoot. Using Lapua's CD data in QT, it estimates that 50fps on the 139 makes a difference of 2" in a 10 mph wind at 1k. Since I've made the investment in the 6.5, I feel that's no where near enough benefit. I have been shooting the 123s, and I do intend to switch to the 139s when I shoot up the supply I have.

Re: Any 6.5x47L shooters, change over to 260?
I switched from 6.5x47L to 260Rem with my TRG-22 for two reasons.
1/ Mil tolerances in the TRG (firing pin/hole) meant I could not make full use of the higher pressure Lap case without experiencing primer problems. I had severe cratering at 2800 using Varget. A friend's TRG also kept blowing primers.
2/ The shorter round tips nose down and jams when single round feeding the 139s. (mag feeding is fine)
The TRG had no problems running the 139s over 2850 and the 123s over 3050 with AR2209 (H4350) during load testing for the 260Rem.

Re: Any 6.5x47L shooters, change over to 260?
I am pondering the switch from x47 to 260, or adding a 260 just to have a rifle that I can readily buy ammo for in a general sporting goods store, rather than be stuck to reloading due to my travels/locations.
not sure that adds anything worthwhile, but.....

Re: Any 6.5x47L shooters, change over to 260?
I shoot both, my 260 barrel is getting long in the tooth. When it goes I will do another 260 and will run 243 Lapua brass to handle a little more pressure and velocity. Accuracy wise the 260 will stand toe to toe with the 6.5X47 in everything up to high level BR comps.

6.5BR, FWIW, I shoot a 6.5x47 and absolutely love it. IMO, I would rather have the x47, but I'm sure someone will tell me and you why I'm wrong. I have reloaded for awhile, and have never got as good ES and SD #'s as I do with the x47. I think it is due to the design of the case and the small primer hole. BTW, I can get 2850-2875 w/139's and 140's, 2930-2950 w/130's and 3000 plus w/123's.

Re: Any 6.5x47L shooters, change over to 260?
I,m a big 6.5 fan
260 like 308 has seen better days, sure they both work but there are better options....IMHO
X47 + RL17 = big smile and pert near 6.5-284 performance
nay sayers go over to 6br and do some reading 2950fps +
6.5CM same as above, esp now guys are making brass from 22-250 lapua stock
thou i run x47 in both my pig gun n soon to be f class rig
Best option period IMHO
6.5 GAP
Shown 243 on left and 6GAP,
SLR
243, 6SLR, 6.5SLR
Yes i realize i ref 243 and 6GAP, 6GAP easily necks up to 6.5 and 243 is just a necked down 260
Case efficiency is what it all about, x47, 6.5gap, 6.5SLR all are better than 260...IMHO
So If i switched from x47 it would not be to 260, better options out there

Is the 6.5SLR a 260 with a 30 degree shoulder?

Re: Any 6.5x47L shooters, change over to 260?
Well I have nothing against any 6.5, the magnums burn more powder than I need to get the performance I need, and the lesser known rounds are not in line with my desire to K.I.S.S. and have the option of a variety of factory loads, and various brass to form if desired/needed.
As good of accuracy and velocity that is being had with a good 260, for my needs (hunting and informal paper), not formal competition, I think my custom action/bbl rifle in a 260 will be fine. If not, then I will try a 47 next, but it seems some have had idiosyncracy's w/47 as well, so it's not w/o some some issues notably primer cratering.
If a few mfg. in the US made brass and ammo for the 47, it would be a no brainer, but that's where I lean to the 260 for now. No doubt the 260 SHOULD have had a better case design, albeit similar capacity would have been fine, my 6.5/308 I had done in the 90s always seemed like it could have used a longer neck, but current users seem to get very solid results, when listening to the groups they are shooting.
I appreciate all the info, just wanted to see the general consensus, and realize all shooters experience varies, I just rather K.I.S.S. for now for the small potential for gain in accuracy, for the shooting I do, mostly to 415 yds at my local range. I may join another range where I can shoot 1K, that remains to be seen.
Thanks all. I will post results when my rifle is completed/range tested, pretty set on the 260.

Re: Any 6.5x47L shooters, change over to 260?
I like the fact that the SLR's have a longer neck, it'll push some of that heat further into the barrel and leave the throat a little less hot.
I've got a buddy that's shoots a 256 Knewt. It's got a super long neck on it also. shoots like a dream and he's got well over 3000 rounds down the barrel with very little degradation.
