The address lables work well.
Also having the turret housing come up against the front ring will work if the adjustment housing is made as part of the tube. If the adjustment housing is a seperate piece and you can see silicon around the tube to seal it then don't let the ring contact the housing.
One other thing I noticed was that the machined in scallops on the Super Redhawk frame had some marring where the semi-circle puts pressure on the frame. I thought to myself maybe a thin peice of lead or aluminum foil would lessen any frame marking.
I have the same thing on my 480 SRH. I have tightened the rings a few times and they have stayed tight. This gun will stay scoped so the deformation can't really be seen.
I don't think aluminum or lead would work very well as they are soft and would let the rings loosen over time.
