On all aluminum rings, I generally don't go past 20... 25 max with steel. I lap my rings though and use dykem to verify 100% contact.
Some would go no more than 15 and 20 respectively... but I don't use cheap scopes, and I've never "crimped" a scope in my life.

If the rings are close enough to the turrets (the rear turret in particular), too much torque can pinch or otherwise damage the erector tube... and turn the scope to junk.

I think, and this is just a guess, that more good scopes get damaged from over-tightened rings than just about any other causes combined.

You might want to back off and retorque to 20 in.lbs.
