Valve pins comparison test

In this video I show the difference in power depending on the type of valve pin used. I compare a standard aluminum pin with a steel replacement pin which differs in length. The dimensions of the pins are from 6 to 9mm. The HDR 50 revolver is available without permission and is used for entertainment and self-defense. As ammunition, you can use rubber balls, rubber-steel balls and balls made of other plastics, glue etc. Visit my channel for more. #masakrachannel #hdr #hdr50 #t4e #selfdefense #test
