I don't think it's your barrel although from what I've found the .280 and the AI version do like a longer barrel 24" and above.
I've tried a number of cal of the years in the .280 length case and I've always gone back to the shorter .308 length case as the most efficient for vol vs barrel length and powder used.
As Kelton has said all my testing on the .260 and Creedmoor has been in either a Tikka or Sako and with the tikka i always have run a long mag and long bolt stop.
My loads i would say are above book max i just use a good Chrono when doing load development and do a ladder to watch for pressure and flat spots in speed.
Im picking RL26 would be a dam good powder in the .280.

yeah no doubt, sadly I gave the 3 containers to that same mate that has been setting up a 7RM

Its hardly fair comparing someone's handloads to Hornady factory but yeah I should claw back some speed with 2225
