Interestingly ,the late Jeff Cooper of Gunsite and IPSC fame had a test for new students to Jeffs basic rifle school course at Gunsite. Before the course began a student was asked on demand to take their rifle and from an unsupported prone position ,put 4 of 5 shots into a 9" circle (head shot ) at 300 yards .No sighting in shots . Most students had scopes on their rifles.In all his years as owner/instructor at Gunsite not one person could do it except a handful of US Marines that obviously are trained in rifle marksmanship to a high degree. Jeff stated the amazing thing was almost all of the students THOUGHT they could do it. Jeff stated that this test was a facsimile of what the average Boer rifleman could do with his 7mm Mauser with iron sights). At Spion Kop, Boer rifleman decimated the British with mostly head shots from long range. Daniel Morgan's rifleman during the Revolution had to pass a test which they had to put 3 shots consecutively into a 2"x 6" vertical post at 200 yards standing with a Pennsylvania long rifle. Their best shooter Tim Murphy would do this easily at even longer distance . Cooper says the reason for such poor marksmanship today is the use of the bench rest. People are obsessed with shooting tiny groups off double bags and have totally lost (or never found) their rifle skills. When I go to the range I never see people shooting from positions and only from the bench. Cooper was right.
