Exchanging ammo was the obvious first thing to try. That done the next step should be send it back to Savage.
Or continue looking for yourself.
Very unlikely the firing pin itself is the problem (though it is possible). Check the back of barrel and see if the firing pin has made a dimple or pit so the cartridge rim is no longer fully supported right where the pin impacts. That could do it but I doubt it in this case (though very simple to check out).
Remove the bolt and manually check firing pin protrusion if possible. Remove firing pin and clean pin channel, may just be a piece of debris limiting pin travel or causing a cushioning effect.
That done and everything still looks fine then it moves to the mainspring. Maybe too light, too short, rubbing too much on the inside or the outside.
Just walking on the edge of of my grave.
