I have a Duane Wiebe custom takedown 500 Jeffery. Range work has been limited, you can look through a few old posts in this forum about my experiences with it. But... it does appear to return to 50 yard zero for me. At least as much as I've shot it.

When the weather warms a bit and the snows stop, I'll definitely get work with this one, but my initial verdict is - yes, very accurate.
