Re: Protecting my scope from the rings...?
Your post begs the question...Why the $60 rings with the $3000 scope? The cost and time you spent lapping them would have been more than made up for by purchasing good rings and skipping the lapping. 6 S & Bs, DOZENS of times on and off different rifles, Seekins Rings, Larue Mounts and AI Mounts. Never lapped ANYTHING. Never bedded a scope base. SEEKONK TORQUE WRENCHES. Never had a hint of a a ring mark.

Lapping the rings will both make a more solid mount and protect your scope.
How i did it:
Lapped my TPS 34mm steel rings by making a bolt to the same diameter as my PM2 (33,8mm). Then i mounted the scope rings to my rail and tightened them good. I applied lapping compound (150grit, but could be finer). and rotated the bolt to grind the rings.
Make sure the rings are totally straight on the rail, by pushing it forward so the recoil lug rests in the groove.
Add lapping compound:
Mark the upper parts of the ring, this is IMPORTANT!
Rotated back and forth 10 times and cleaned to check. As you can see the rings werent straigt at my rail. i felt this when i mounted my scope the first time, and that is why i went through with the lapping process.
Upper part:
Repeat: clean, check, add new lapping compound, rotate and tighten the rings. Make sure you dont take off to much material, so it wont tighen on your scope!
Third time's the charmed:
About 80% of the surface treatment is gone, and im positiv the scope will rest much better in the rings now.
The bolt after the treatment. I used soft construction steel for the bolt, so the particles would get stuck in the metal and grind the rings. It could have been even softer metal, like copper or aluminium, but this steel was all i had.
Then i mounted the scope again leveling it to the rail like this:
