Both those guys shooting the Mag 10 are bigger than I am. I can tell you when I was using my 10ga. NEF Pardner and the shells from Nitro Company that the gun kicked far harder than the Mag 10 in the video. One morning when I shot a bird I seriously thought I had dislocated my shoulder. Used it for 4-5 years and sold it. It kicked far harder than my 300 WinMag does.
