The problem arises when the hunter with his magnum rifle cant shoot it very well .Recently at our rifle range a fellow shooting his 338 magnum from the bench shooting tiny group after tiny group. When he witnessed me zeroing my rifle from the sitting position (I almost never shoot from a benchrest) he asked me why . I replied "well ,you never see US Marines shoot from a bench and they are the best shots in the world why don't you try it" Well this guy was so bad off the bench he couldn't hit a 12"x12" target at 200 yards from any position. He was totally astounded watching me break clay pigeons laying on the berm from the standing position. I have seen this so many times.Nobody shoots from positions anymore ; they come to the range ,plop their fat asses down at a benchrest with double bags and begin to shoot. And while their rifles are most excellent ,they themselves are poor shots .The PH I use when I go hunting in Afrika makes shooters zero their rifles from shooting sticks; he has no benchrest in sight. He told me the average American cant hit an Impala at 100 meters and 1 in 20 can do it from shooting sticks .The magnum guys are by far the worst. My PH friend attributes this to Americans fascination with shooting tiny groups from the bench and neglecting their rifleman skills.
