If you are a guy who installs the stock, torques it down and leaves it alone, you probably don't need pillars. What I like about them is that it relieves you of the necessity of a torque wrench and when you take the barreled action out and put it back in, the zero is maintained. I used SS pillars and tight is tight. I travel with the barreled action and stock side-by-side in an aluminum shotgun take-down case inside a duffel. When I arrive at my destination, I reassemble and the rifle is still sighted in. I didn't have good luck with this before I went to SS pillars.
No matter what anyone tells you, a metal pillar is NOT going to compress as much as any fill that McMillan uses.
