Not to pour salt into a wound, but my old 6.5x55 Swed made in 1901 will put 5 into under a quarter at 100yds with Winchester white box. Something is as loose as a goose. Does the rifle have iron sights, if so may try them. If they shoot good then it has to be in the scope system and I have gotten scopes with a loose erector system right out of the box. Don't keep us in suspence, if you find out what it is, let us know.
