No load recommendation, just a comment that Varget is quite a quick powder to be using in this case behind this size of bullet. You'd likely be better off with H4831.
What rifle? Is it an M96-type, and do you wish to respect SAAMI-level pressures (which are quite low)? Or is it a stronger more modern action, in which case you can safely load to full pressure levels?
With the particularly long bearing surface of the bigger 6.5mm bullets, you can see much greater than typical variations compared to most calibres. Take the "reduce loads by 10% and work up" twice as seriously as you ordinarily do. (I can show you a couple of destroyed pieces of 6.5x55 brass, and a cracked M96 bolt that goes with them)
