No. Lapping eliminates high spots on the ring inner surface, such more of the ring is touching the scope. Remember, your rings have gaps between the top and bottom when installed, such they will always have ability to create tension. Once the lapping mandrel is used a few times, it too is "lapped" to be slightly undersized, which is when you get your best fit for scope contact.
I check all of my rings once installed. Some need lapped, some don't - Warne, Seekins, Larue, Spuhr, Nightforce, Alaska Arms, you name it - many are great out of the box, many are not. Burris Signature Zee and Signature XTR's are the only rings I use which I don't at least CHECK with the mandrel. When you get the cheap rings like Leupold, or worse, lapping is almost guaranteed to be needed.
Can a deer hunter who never buys any scope more than $300 be happy killing deer at 200yrds and less without lapping? Sure. Doesn't mean it's right, just means they don't have very high expectations for their gear.
