I did a 5-part review of the 6.5s in the e-zine Target Shooter:

It likely won't help you as has been said many times before and since, there is nothing much in performance terms between the 6.5X47L, Creedmoor, 260 Rem, and 6.5X55mm and all are capable of outstanding precision in the right rifle. It always comes back to personal preferences, availability of factory rifles (if the smokepole is so restricted), brass, and price. 6.5X47L may have a slight edge in out and out precision, but has only one manufacturer of its cases and almost no factory rifles on offer.
The 260's restrictions caused by deeply seated bullets in magazine rifles are often overstated by critics and despite being the least 'sexy' of the modern smaller trio, it can perform as well as the others and often shoots outstandingly well despite its 'old-fashioned' longer more tapered case and 20-degree shoulders. (I'm just starting a load development programme for a long-throat 260 to be written up next year sometime.)
