Mine came from the factory with a bad barrel. As in, 2-3" groups @ 25yds kinda bad. Tried five different types of ammo, POI shift between 17 + 20gr was unreal, too. Since it was new, Savage was very good about taking it back and replacing barrel. Came back with a proof target that I confirmed shortly after,it'll hold an inch @ 100yds now with new tube.
How old is yours, and did you buy it new?
