Back when I was very active in the shooting sports, there used to be a bullet trap designed for home use in .22 long rifle caliper. This trap had an extreme angle in its backplate that led to a curved portion at the lower end of the trap. The idea was that the bullet was deflected downward, entered the curved cusp and spent its remaining energy quickly and safely by looping in the curved portion. Sounds to me like you could use a trap designed for powder burning .22's.

Of course this all assumes you don't live in <deleted by Admin> England or Austrailia.
