No one has ever doubted that a 22LR HP Stinger can hurt and possibly kill if location is correct. Your test was with a rifle and not a CCW, which, in and of itself, is self-defeating in your analysis. Larger calibre firearms, and higher velocities for pistols is the real great equalizer in definitely stopping a threat. Your test confirms what an FN5.7x28 pistol is all about. Same calibre as a 22 (actually 224) but the velocity can be a staggering 2100-2400 fps depending on ammunition and this is not from a rifle, it is from a pistol. I seriously doubt that the Stinger, if matched against the 38 and above, will fail to exceed the results of your gel test; a tumbling special defense 5.7 with an incredible velocity and delivery "punch" will also confirm this. Bottom line, IMHO, if you have a choice, any 22 is better than a rock, a 22 Stinger is better than a 22LR and the higher calibres or specialty high velocity pistols are even better. Intersting gel test and I thank you for the video.
