I know the US can be gun obsessed at times but I struggle to believe that even a professional hunter who frequents the range in his spare time fires as many rounds in a given day as a Navy SEAL who's entire job description revolves around being trained to deliver rapid and precise attacks under extreme pressure, which is only possible with incessant drills and practice.
People that hunt and shoot guns their whole lives don't shoot guns their whole lives. They shoot guns a few times when hunting and then a lot of times at the range but at a leisurely pace. This is like comparing a package delivery guy who likes jogging to an Olympic athlete.
