I have a new Steyr THB in .308 with a Manners stock and I am having difficulty getting good groups. I have tried several brands of factory ammo and have been getting group sizes between 5 inches and 1 1/4 inches at 100 yards. The Scope is a Nightforce 5 x 25 ATACR with a spur mount so I am confident in the scope set up. I have several scoped rifle set ups and have never had this kind of an issue before. Any ideas why the accuracy is so poor? Anyone else having difficulty getting tight groups? Thanks.
