People play with torque settings etc. with every action, pillar system, etc. etc. out there (even custom actions). Not unique to Savage. Give people a screw or bolt and they will turn it to try to get a better result!

If you don't carefully profile the tops of the pillars to the unique contour of the bottom of your receiver (most Savages I have seen are at least a little warped) the larger metal to metal contact area just makes for more variability.

Of course - if it works for you, more power to you!
