OK, I looked into a post on instinctive shooting, which is not about what this thread is about, really. No problem with folks having fun on the mental and philosophical gymnastics. It's all fun.
Anybody who wants to learn to shoot well instinctivly will do so by doing - getting the feel, and building that into their form/rythm.
Very few words are involved. I'm a tax attorney, so I have no aversion to words or numbers, but more of them is no help on something like instinctive shooting.
My little brother, Joe, who regularly astonished me at age 11 by consitently hitting a 1.5 inch swinging rubber ball at 20 yards with his 31# Wing, fiberglass arrows, and instinctive snap-shooting says it like this:
1. Fix your entire attention on the spot on the target you intend to hit.
2. Raise your bow and draw with your entire attention so fixed that you are an extension of the arrow.
3. Release upon full draw with your attention so fixed, and keep it so until the arrow hits the target.
I'd boil it down to "Look, Draw, Hit".
That's really all there is to it for folks who really want to make it happen. So, i consult Joe on my shooting form, and instictive shooting.
Best way to make a good instinctive shooter is to turn a physically talented 11 year old loose with a good bow and arrows, and once he starts hitting the bulls-eye at 10 yards, move him back to 20. Once the "robbin hoods" start busting too many arrows (about three arrows to a kid in in 1962), give him a smaller swinging target.
Finally, I think the shooting in dim light illustrated it best for me. My best instinctive groups have been in dim light where I could not see the arrow, or the bulls-eye, or the arrow even hit. But I could focus on the center of the target. And, i could hear each arrow slap in next to the others. Funny - I shot a 1-inch group on the very X-ring of my rubber deer at about 18 yards. Made me a believer in instictive snap-shooting.
Then, I tried Dick Palmer's shoot as you keep walking back, 'till you miss. I found it's not that unusual to shoot a 4 inch group of successive arrows at 10, 20, 30 and 40 yards, on the kill zone of my rubber deer. Same for live ones.
Just swinging up, releasing on reaching full draw, all the wile focussing my attention on the spot.
Good luck !
