What make mounts and scope are you using now? I'm also assuming also a .30-caliber (.308, .30-06, .300-something-magnum)?
The groups you're getting from your Vanguard at 100 yards are what I'd expect from mine at 300. That you're having similar accuracy issues with the Ruger is puzzling. Has anyone else fired these two and, if so, did the accuracy issues persist?
Unless you know you have junk glass on the Vanguard now, attempting to solve the problem by buying a new scope may be throwing good money after bad at this point.
