I have personally run a 6.5x55 18.5" + DPT can on a Tikka T3 action running the old 140grn AMAX rounds at approx 2675 fps ( I've double checked my data). That particular load absolutely sacked a ton of Reds and plenty of Sika that I shot from 10m to 350m with no doubt it would do fine at longer range.
Don't get caught up with the FPS figure, the 6.5mm round kills deer well with an appropriate shot.
