My opinion would be to ditch QL and stick with Viht`s tried and tested published data.
I reload 260rem which is not dissimilar to your 6.5 - it`s its father!
I used N160 but have moved onto N555.
Either of these will get you another 100fps safely.
Whether you need the velocity is another matter - I shoot to 1200yds so for me its a factor.
If you are only going to 600 then the N150 will be fine. (I use N150 in another 260 rifle - 20 inch barrel - with 108 scenars and its superb at 600).
I would start 2gns down from max with any of these powders but be aware of varying case capacities between makes.
If you are not familiar with ladder testing then have a google.

Good to know - Vihts numbers do seem to be conservative with N150 so a move to N160 looks like a better option as it has done well for some in the same club. It's a shame the N555 same out just after i got the 150 and 160 at the start of lockdown!
A ladder test is on the cards for this week.
I've done a capacity check on both the Hornady and S&B so have a good idea of how much room there is.
The plan is to go to 1000+ if possible so any extra fps will help.
Cheers

Another of my club members shoots a Tac A1 using N160, 42gr and a 139 Scenar. I tried the load in mine (and the Bergara.)
No improvement in group size over N150 only a 17% increase in powder usage for the same results
Needless to say I've gone back to N150

His data source?

No one should ever use QuickLoad as a single source of data. It’s lured so many people into doing so. It’s a theoretical programme. Even QL themselves state that any formula must be cross referenced with published data of the manufactures.
