Bench Rest shooters are constantly changing out high end optics. Not unusual for a scope for Bench Rest that costs as much or more than the custom rifle it will sit on top. There is then a lot of used scopes available from all of those changes.
Take a look on www.AccurateShooter.com from time to time and you might find yourself a really good deal on a used scope, many of which now a days come with lifetime warrantees.
