Well, neither can anyone else shoot groups off their shoulder slung up in any position the size of ther test groups. We've got a heart pumping blood that quivers muscles holding our bones supporting the rifle. It's gonna have a 3/4 MOA area on target were its aiming point bounces around in. Most of the time a shot's got off somewhere inside that "wobble" area. Don't long range hunters have a heart, too?
Then our bodies are not as repeatable in position and resistance to recoil from shot to shot as free recoiling benchrest rifles virtually untouched by humans; that adds another 1/2 MOA error or more. And, with metallic sights, we cannot see subtle wind changes as easy as with a scope; that adds another 1/2 MOA of error. Add all these to a rifle and ammo test group size.
Anyone who thinks folks can shoot rifles off their shoulder without artifical support as accurate as they do in free recoil is ignorant of the real limits of marksmanship afield. Take a look at last year's Nationals' scores in high power rifle matches listed in this link:
NRA Competitive Shooting Programs|NRA National Outdoor Rifle & Pistol Championships Results
Pay close attention to the winners and high master's scores. Few scores shot 600 yards and further are perfect with at least 80% of the shots in the X rings (6" at 600, 10" at further ranges) with special attention to the 1000 yard ones; those shot inside 2 MOA.
I don't think any long range competitor can put more than 10% of their first shots at a known range past 600 yards into a 1 MOA circle. What percentage of the long range hunters do that at an unknown range without a previously established zero at the site?
