OK! Picture this. you lay on your back, knees up, feet apart to create a triangle, pistol in hand, hand on hip, barrel/forarm resting against your leg or on top of your boot top, elbow out and on the ground or shooting paddock, creating another triangle, head up resting on your forarm with hand on the ground to creat yet another triangle to support your head. this way you have created as much stability as possible without having to strain to use mucles to hold your head up, litle effort to hold the gun up. very stable. typically we don't use rifle scopes, but I had this one pistol/ scout scope so I used it. I have Ken Lights scope mount extensions on a few of my other pistols and they are nice but not Infinitely Adjustable for eye relief as this set up is. Some pistols scopes don't have as good long eye relief as others. My Leupold does, my Simmons does, but my Burris does not and this set up allows me reduce that distance form eye to scope and give me more field of view at high power. there is another position called the dead frog where you lay on your back, legs crossed as if you were sitting on the floor, and you lay the gun on your thigh gun hand and arm the same more or less as the Creedmor and head support he same.
Hunting coyotes, mule deer or antelope you can sit up and wiggle you way back into a sage brush or up against a tree and put your knees up and together set the gun in the notch between your knees and push your hands all way forward to lock your hand/gun in. creates a very stable position in open country like here in Central/Eastern Oregon.
