Why exactly are wood stocks different than Carbon, chassis, etc.

So on the topic of "dead recoil" of a wood stock vs a CF or "plastic"... Yesterday while shooting the trainer in a non wood rokstock, I had major vibration in the rifle. It was only 3 shots out of 80, I was prone shooting off of a flatbed truck, using front bag and rear bino harness, shooting mat. It sounded like a tuning fork in there and lasted 3-5 seconds... Any ideas what would cause this? I was shooting at 800 plus and did not notice any accuracy issues. Re checked the rifle at 200 ish yards and no vibrations and accuracy was fine. Rifle has 12000 ish rounds on it with no issues in the past.

Ideas?

sounds like something is loose or coming loose inside?

Or just nothing touching the stock to damp out the vibration?

Did magazine capacity change through the shots or single feeding?

What could come loose inside? it was definitely in the butt.

I've had mags buzz and I've had wierd harmonics from bipod or butt contacting something hard.and from low tension on the contact point (loose)..though not likely on a mat.
