That is, scope positioning both on the picatinny mount and within the rings.
 
Obviously the proper eye relief is paramount.  I have a one piece Badger picatinny rail mounted on a Savage 10FP LE.  My rings are Burris XTR.  I've used the Wheeler kit on them and they're properly lapped.
 
1)  I have no real idea about the ideal place to mount the scope on the Badger picatinny rail for least stress on that part.
2)  It seems to me that mounting the scope sa far rearward in the rings as possible (again, with proper eye relief being paramount) the better.  My theory being that if there's more scope forward of the front scope mount there's more inertia trying to tear it out of the rings as the rifle kicks up and back.  IOW, it seems the scope would less stressed in the red rings rather than the blue rings in the image below.

I try to mount my rings right over the base screws if possible.  It seems logical to me that would offer the most strength while flexing the least.

Never really thought to much about position on the scope tube itself.  I just don't put them right against the eye piece, turret section or where the bell begins on the objective. 

On a small heavy rifle like you .308, I don't think I would worry to much.  As long as you have good mounts and they are all square which it sounds like you have verified.

I normally mount my rings as far apart as possible while still allowing proper eye position.  My scopes mainly have rings in the red position in area C and the blue in area D.

Well, if you put the rings over the the base screws, which I don't disagree with because I'm ignorant... but it makes sense to me what you say, then the scope position is completely based on proper eye relief.  That sounds fine to me.  I appreciate all the quick replies.

Same here. Also, check your eye relief from prone, kneeling/sitting and offhand (standing) positions.  I think the farther apart the rings are the more rigid the scope mounting will be. Like supertool said you won't have to worry much on a .308 anyway.

This also makes good sense to me.   So, for the two replies so far...
 
Rings over the base screws.  This means the pull on the base screws is tensil rather than shear.
 
Rings as far apart as possible still giving proper eye relief.  That would have to help reduce inertial force (is that a proper term) on the front scope lens.
 
Thanks, I'll go see if I need to modify anything and report back with a pic.

Alot will just depend upon the scope tube length itself.  Here are some different ones of mine.  I just don't think it is going to make that much difference on a typical sized scope.

That distance between the white lines is what would worry me with the rifle kicking up and back in the direction of the arrow.  It almost seem like another ring just in front of your front ring would help.  Again, I'm new to the game.  I just want my scope to last and stay accurate for a long time.

There is not actually any more base to put it as far forward as you are saying.  THat scope never had a problem though.  But I did not shoot to many rounds with the setup before I sold it.
