How to quiet 22 lr rifle, muzzle in box??

I had a friend on the USAF shooting team many many years ago. His 22 target rifle had a weight/balance tube that attached to the end of the rifle. It was just a plain metal tube specifically for balance. it had no baffling, etc. It was about 1" inside dia. It also had a silencer effect even though that was not its stated purpose.

These are commonly referred to as 'bloop tubes' and are frequently used on smallbore Silhouette rifles.

I have used the cardboard box and egg crate foam to muffle a smallbore rifle, it worked well.

This thread has me thinking..

What if one were to create a tube made up of several concrete cone-shaped plant pots that have their bases cut out to replicate suppressor baffles? Perhaps find tires of appropriate size to fill the gaps between the pots.
