Picked up a model 16 Lightweight Hunter in 6.5 Creedmoor (20" barrel) to replace a 6.5 Grendel I was hunting with. First light tapered barrel rifle I've owned and it is a hunting rifle so what should my expectations for accuracy? Can it be a consistent 1-MOA gun with hand loads or is that unrealistic? Groups with factory ammo have been as small as just under an inch to just under two inches.

I don't want to spend a bunch of time and components on load development looking for the results of my long range HB rifles if that's really unrealistic.
