Absorbing bullets to prevent penetration and ricochets, how?

[BadgerDK]

Building a killhouse and want to have multiple teams in live fire exercise at the same time - without killing eachother and themselves from ricochets.

How would you set up the wall materials?

Apply .rvmats from P:\CA\Data\Penetration to your walls in your fire geometry.
