Probably start around 38.5 at 2.800" and work up to 42, but I'm just speculating as I'm not in front of my PC. MY PC that is. If you don't have the numbers when I get home, I'll run them for you. What OAL are you loading to?

Hey man! I totally spaced out about this reply! Very sorry. 38 is probably on the low side to start with, but like I said, I was just guessing. Based on this QL table, I'd probably start more around 39.5 and work up 0.5 grains to 42.5, then 0.3 from there to 43.8. Watch for pressure though, every rifle is different.

Cartridge          : 6.5 Creedmoor Hornady
Bullet             : .264, 125, Nosler PART SP 16320
Useable Case Capaci: 49.831 grain H2O = 3.235 cm³
Cartridge O.A.L. L6: 2.825 inch = 71.76 mm
Barrel Length      : 26.0 inch = 660.4 mm
Powder             : Alliant Reloder-16

Predicted data by increasing and decreasing the given charge,
incremented in steps of 0.407% of nominal charge.

Remember, only you can make sure you don't blow your face off. Load with caution, and only use this data as a reference. Do your due diligence, and check out Alliant's website as well. They typically only have Speer bullets in their data, but cup and core projectile data is pretty much interchangeable for the same bullet weights... within reason. And by that, I mean starting loads are a safe place to start. I don't know your experience as a reloader, so I have to provide this warning. Nothing personal, obviously.

HEY DADAJACK...yes...have checked Alliant website...have their 2018 Loading Guide....Nosler guide has RL17 Data but not RL16...I plan to start at 40.0gr...and will watch the velocity....have my trusty LabRadar....works great....have been reloading since 1968...Alliant data seems to top out around 43-44gr...for 120 to 130gr bullets....gotta watch with the Partitions...they usually show higher pressure due to that partition belt....your Quickload starts off low which is ok for these partitions....and my Sako A7 has a LOOOOONG throat which tends to lower pressure and speed...
Thanks Again...
