Was I Too Tough On It?...You Be The Judge!
This expert-level analysis from Tools&Targets details a ballistic gel test comparing Underwood XTP and Federal HST 10mm Auto ammunition. The host, demonstrating advanced knowledge, found both rounds achieved 24 inches of penetration through a four-layer clothing barrier but fell short of his 700 ft-lb energy threshold for 'true 10mm'. The Federal HST exhibited greater expansion, while the Underwood XTP retained its weight better, though both performed well overall.
