The 260 will do better at longer ranges, the 6.5x55 better still, and the 6.5-284 even some more.
I have shot at 1000 to 1500m with the 6.5x55 and the 6.5-284, alongside 6.5x47s and 260s, and the lighter bullets that tend to be used by the two smaller calibres tend to lessen the performance past 1k. On sevareal occasions we could not even spot the 123grainers (some hit, some were "lost in space"), while we were hammering the steel targets at 970 and 985m with 139grain bullets out of 6.5x55s
On the occasions where i have shot the 6.5x55 and 9g bullets against 6.5x47s or 6.5x55s with 8 og 8.4g bullets at 1000 or >1000m, they did not stand one chance. The repeatability of a 9g Scenar travelling at 900m/s simply cannot be matched by a 8g one at 850...
Step up to 6.5-284 or 6.5x65RWS and you are effective at 1250m, where even the 6.5x55 is somewhat challenged.
The difference between 1000yards and 1000m is more or less te edge where the differences really come out. What i say is for normal varying wind conditions, in a calm even the 308 will be reliable and accurate past 1200m, if you can dial the elevation.
So to sum it up; the 6.5x47 is a fine caliber <1000, but is severely challenged past, and would not be the caliber of choice in my world. Most 6.5mm bullets need serious "oomph" to work at 1k, and unless one has a great supply of cheap 6.5mm bullets (as we do here in Norway), one would be advised to look at something 7mm. The 284win comes to mind as a first, but most anything 7mm will be more effective past 1k than 6.5x47.
Personally i prefer my 7mm WSM
over the 6.5x55 as soon as we start seeing 4digit range, or before. The clang in the steel from a 180gr VLD is also very impressive compared to the ding from the 6.5x55 - it leaves no question, where 3 spotters might be arguing if one had hit with a 6.5x47 or not...
