What are these small holes in my model 16 barrel? Is this a flawed barrel?

Do the savages need to straighten the barrels? I know they do straighten the barrels at Rem as a result of the hammer forging but surely not after buttoning the barrels????

All quality barrel makers check and straighten if required. One reason that Savage factory tubes are good!
