SoTexCurdog,
I still don't think you've done enough shooting to prove anything, or groups with enough shots.
There are a bunch of possible reasons that might have happened, including barrel attachment, bedding, scopes, etc. But I would have to try 5-shot groups before guessing Savages have some magic quality that results in "good triangular groups."
