Turret or bell against a ring - no way. "Glue" - no way. Used mostly plain old standard dovetail or windage Leupold or Burris bases and rings even on the handcannons, but I always lapped the rings for maximum contact. No anything else to hold them, no tube damage and never had a scope slip. Not on any of the Contender bad boys, nor the Encores including the 416 Rigby. Folks use Zee rings and achieve about the same, I never felt a need to use them myself. Did use the T'SOB's some, Redfield, Conetrol and Millett and others on the 6-screw bases, but the standard Leupold or Burris got it done just fine so was the first choices on most of them, even many of the bad boys.
If I remember you just got a 357MAX... a kiddie cruiser as Contender cartridges go so not needing anything special for scope mounting IMO (2 rings is plenty), and the Leupold M8 2X is a strong scope. Lap the DD rings and go shooting/hunting.
