Denziel Washingon saved my life(bullet setback)

[FIVETWOSEVEN]

I set a .45 ACP round in my brothers 1911 in under 10 rechamberings and a .40 S&W in under 20 with my XD to the point that I wouldn't want to shoot it. I tried it with a 9mm Hi Power and couldn't get it to set back after doing it probably 30 times and then I just gave up at that point.
