Any help would be appreciated.
Welcome to LRH and enjoy! Congrats on a very nice rifle and chambering.
Your load combination (powder capacity/burn rate, primer, bullet type, case capacity, etc ...) affects the velocity for your particular rifle.
For instance, in my .270 AI loads, I can get ~100 more FPS using H4831SC over H1000, Win case handles better pressure than RP case, WLR primers are hotter than BR2s, etc ... Others will be here shortly to chime in.
Find the best combination out of your rifle and have fun with it.
Good luck and happy safe reloading, hunting, and shooting. Cheers!
