Game reaper (DNZ) mounts are the only mounts I will use on any of my rifles since discovering them a few years ago.
If I didn't use the Game reapers I would use Warne Maxima bases with Warne rings. There is a reason that the Military adopted the Picatinny / Weaver system a long time ago and are still using it today.
I wouldn't give you a nickle for a set of standard Leupold bases and rings.
