I am glad you found out what the issue was. I own a Savage .308 and have owned a Model 110 .270 in the past. Never had to call the service department or take the gun back or anything like that. All they have ever been was tack driving rifles. Now the old ammo issue I have had happen in my remington 7400 and 742 but old surplus ammo or old factory load ammo can cause these type of issues.
