The ability to very easily make .260 brass from .243, 7-08, and .308 makes this a no-brainer to me too.
I have always chosen the 243 to load for my 260. The 308 causes a doughnut in the neck and this increases pressure . Yes it can easily be removed with a reamer but I choose not to add this extra work to my reloading. 7mm-08 is no problem too. It necks up easily. The problem with the 260 has been that when Remington came out with it, and all the rifles had the 1-9 twist. The 260 performs much better with a 1-8 twist. Cooper rifles have the 1-8. I had known about the 6.5-08 A Square for many years before Jim Carmickle called his version ( The 6.5 panther) was picked up by Remington and named the 260. I have several High Power shooters( silhouette) that have been shooting the 6.5-08 for many years. The other big problem was the 260 ammo from Remington was total crap. Winchester was miffed by the whole idea that their 308 had been necked to another caliber and was being claimed by Remington. They swore that they would never make any brass for the 260. I and some others found the 260 Rem brass to be too soft. All these things plagued the 260, in spite of it being a good cartridge. When the Creedmore came along, it was a better idea and was handled different. Mr Emory said many times that it was what, the 260 should have been. Personally I wanted the 260 to have a longer neck and a 30 degree shoulder. Well, that has been done as well as the 260 SLR For some interesting reading on several 6.5s go to 6mmbr.com that website has several calibers and a lot of information about them. One of my best friends has the 6.5 Creedmore and he loves it. It is very hard to tell much difference in the two cartridges performance. I remember talking with Sierra and Speer about loads and then Hodgdon, and it took awhile to get things sorted out, but actually there is now quite a bit of info on both, calibers and there is much better choices of bullets than the late 90's when the 260 started showing up.
I don't think you can go wrong with either caliber, and I also don't think either one will disappear any time soon. The 6.5 X 55 and the 7X57 Mauser are both calibers similar to what we have discussed and they are still here. Stop and think just a minute how that we sometimes come full circle on some of the calibers. We start off with a small and light gun and then ( in our Minds ) Progress to magnums or whatever, than as we get older we go back to the smaller light weight calibers. Any of you that choose one or both of these calibers will enjoy it for many years to come.
Just Food for thought The 140 grain Nosler Partition has been a good bullet for Hunting as well as the 120 gr. The Scenars and bergers excel in the long range department.
Oops I got sidetracked !!! I was supposed to choose which one to buy or shoot?
