When I first started shooting traditional I thought "instinctive shooting" was shooting without the aid of external devices like sight pins. Then I went to the Leatherwall and got a rude awakening. If there's anything they like to beat to death over there it's the ol' what's instinctive, what's not. Depending on how you define "instinctive shooting," it has it's place.
Snap shooting is another term people like to beat to death. I always thought snap shooting was just a real quick shot. Lowandbehold, the trad police found me guilty of that as well. Apparently a snap shot is an out of control shot, regardless of whether it's fast or slow. I've always liked the looks of a real quick shot (what I would call a snap shot). No doubt they have their advantages in hunting situations. However, I've always liked the draw, anchor, line the arrows up, release method. If it takes me a few seconds to line the arrow up, if it takes me ten, that's what I do.
I was at a shoot last year in Coshocton, Ohio and got on fire (figuratively). I was shooting so well that I started doing what I would call snap shooting. As soon as I hit anchor the arrow was gone, and it hit its mark. Unfortunately that bred some target panic because I got to where I wasn't lining the arrow up, but was still releasing as soon as I hit anchor, even before I hit anchor. I don't shoot in the style that would be considered "purely instinctive," but that day I was so in the zone that the end result was the same-until the target panic developed.
I enjoy reading Fred Asbell's articles in TBM, however, I can't stand him at the same time. I don't doubt Fred is a great shooter, or that his style of shooting will work if you do things as he instructs. What I don't like is the perceived attitude that his way is the only way. It seems he writes as if the only way to shoot properly is to do it his way. I don't do it his way, far from his way, but I can still shoot. I've impressed people with my shooting, I've impressed myself. That doesn't mean I don't have my stink bad days just like anyone else, but I'm still capable of putting and arrow where I want it to go.
Overall I think it all comes down to a bunch of semantics that people are entirely too anal about. There are several basics to any shooting style: drawing, holding the bow, anchoring consistently, having the arrow directed at the intended target (whether you look at it or not), and a clean release and follow through. Come to these however you come to them. Don't worry about what it's called, who shoots what way, or how much they despise the way you do it. Whatever gets the arrow where it's supposed to go, bottom line. Ain't no deer gonna give you any grief over your shootin style.
