It is the standard material for backing body armor in tests, though. The purpose is to measure back face deformation if the round is stopped.
Your test method is invalid. Clay, as a backing material, makes it EASIER for a bullet to pass through soft body armor. Body armor that performs well when backed by clay performs better in actual shootings because the human body "gives" behind the armor which dissipates energy. Clay does not "give" like the human body.
Believe it or not, according to Duncan MacPherson, a pillow is a valid backing material.
Clay is a test for body armor performance not bullet performance.
