This video compares the ballistic performance of 40 S&W and 10mm using Underwood Ammo 180gr JHP rounds fired from a Glock Gen 4 Model 20. Both calibers penetrated the 16-inch gel block, but the 10mm exhibited significantly more violent expansion and a wider wound channel (0.912 inches) compared to the 40 S&W (0.859 inches). The 10mm also retained slightly less weight (170.5 gr) than the 40 S&W (178.6 gr), indicating greater energy transfer.

This video from Kentucky Ballistics revisits a comparison between 9mm and 10mm calibers, aiming for a fairer test than their previous casual attempt. The comparison involves shooting through water jugs, wood, steel, and concrete. Specific firearms used are a Canik TP9 SF in 9mm and a Glock Gen 4 Model 20 in 10mm.
