As Frank mentioned, I am reading the book, and I am almost finished with it.
There are a lot of good tips on form in the book, and they make sense. Bernie does say " You don' t have to do it my way, you only have to do it the same way every time."
If you want to really get into what he is saying about letting everything other than aiming be done by your subconscious, you do have to put your time in on the blind bale shooting. I have HORRIBLE target panic when trying to shoot with fingers. It is much less of a problem with a release, which I usually squeeze like a rifle trigger, slow squeeze, let the pin float, concentrate on the target. I got about 10 days into the blind bale stuff, and had to shoot some for real to get equipment set up right. Then I went over and shot some with Frank, and it took a few shots to get onto the target center. That' s not going to cut it for hunting.
I am going back to my old form until hunting season is over, then after the season, I will take the whole " cure" which can last 42 days according to the book.[

Some guys do not like the book or Bernie. I have not met him in person. I do think the book can be helpful if you have the time to do what he is saying. There are other ways to help your shooting that may be just as good. I guess hiring a qualified coach would be the best.
BTW, I got the book from Amazon.com and saved $10 over the advertised price.
