.357 Magnum Penetration- Xtreme Defender VS Hard Cast

Testing out the difference in penetrating capabilities in a 4" barrel with .357 Magnum Xtreme Penetrator VS .357 Magnum Hard Cast, both by Underwood. Going through my Jug-or-Not box but with a much thicker than normal fabric barrier and 3/4" pine board behind my usual bologna pack. Which one will perform better? Watch and find out! Thank you to Marc C for donating this Xtreme Penetrator ammunition and as always, appreciative of any channel help :) https://www.paypal.me/gunsamrevolver
