Does seem excessive, even if it just doesn’t like that load, but as was said, I’d try some other ammo. Also, some new Savage barrels just need some rounds to settle down. 100, 150rds maybe; just normal shooting & cleaning. But if by then it’s still a pig then yeah, it’s likely the barrel & you’ll need to decide what to do.

As for getting a refund, you’re likely out of luck there. Warrantees make good, but they aren’t in business to give refunds unfortunately. Good luck & let us know the outcome.
