RWS claims about 870 m/s with a 9.2-gram (140-grains) twin-core bullet in 6.5x55mm (29-in barrel). http://rws-munition.de/en/hunting/products/rws-centerfire-rifle-cartridges.html?cHash=8a74df38eb7cb8d28e0d1afcbeb189b9#!0/40/28 .
I think that 870 m/s = about 2854 f/s. I guess that would go about 2700 f/s in a 24-inch barrel.
