.357 Magnum (Unconventional Ammo) Hard Barrier Penetration Test

Testing less common .357 Magnum cartridges through a hard barrier penetration test. What I mean by uncommon is other than JHP rounds such as ARX, Full copper HP's and Xtreme Penetrator rounds. The hard barrier is 18 gauge steel followed by a bunch of wood. Always appreciative of any channel help :)
