Hi fellow shooters I recently purchased a 308 Ridgeline and I can't get it to shoot under an 1 inch group Maybe someone would have load data to share that shot good in there ridgeline

Not much additional info to go on. Is this the Christensen Arms light weight hunting rifle? Is the grouping mentioned with factory ammo or with hand loads? Also being shot off of sand bags, bipod or a steady rest? What about scope and magnification? If a new gun, it may need additional break in time, or if a light weight hunting rifle with a lower powered scope, 1 inch is acceptable for hunting. If this is with factory ammo, try a box of premium ammo and see if that shrinks the group size to an acceptable level.
