Since there are so many choices today for factory ammo, I would like someone else to decide what brand for me to use in my rifle. I have a savage rifle in .308 caliber. I will be using it for whitetail mostly, shooting in a range of 100 to 300 yards. I tried sighting in with federal 168 grain at 100 yards and did not get tight enough groups. I want to move up to 180 grain, for better accuracy and terminal ballistics. Anyone have any suggestions? I know the routine (shoot,shoot,shoot) to find what my rifle likes. I am simply trying to find input from others, for a good factory round.
