Just for fun this morning...Went out and shot 4 different selfdefense rounds into a ballistic panel. The ballistic panel was an expired Second Chance Tri-Flex armor pac IIA. 5" x 8". Rounds Used: Hornady 90gr XTP jhp Fed Hydra-shok 90gr jhp CorBon 90gr jhp Speer GoldDot 90gr jhp All four rounds were contained within the thin panel. Only the Fed Hydra-shok traveled away from its entry hole. The CorBon expanded the most and had a more noticable impact on the panel. The Gold Dot had the second stongest noticable impact. Shot from approx. 2' away. The CorBon expanded the flattest of the four. The other three were approx. the same.
