I really question what it is going to do that a plain old 260 Remington won't do tho.. I have a VLS Rem in that caliber and it is excellent...especially after I tweaked the trigger...
If there was better brass readily available for the .260 I dont think we would even be seeing the various 6.5 offerings. All offer about the same case capacity and external ballistics. I think its just a matter of what you want your casehead to say.
