Only perfect technique practiced makes perfect. Maybe I should get a lesson or two. Or get some tips from some accomplished shooters at the range.
Kirk I got a PHD in the school of hard knocks when it comes to shooting at targets and missing game. But I got better with trial and error without much coaching. I posted about my experience before on forum but a few years back sort of lucked into a weekend of hunting and shooting with an Orvis shooting instructor by the name of Todd Rogers. He was part of a group that with Orvis they put out a book Guide to Gunfitting. Their premise though before even attempting a gunfit you should have proper fundamentals in shooting so first half of that book was dedicated to proper shotgun shooting technique. It mostly teaches and preaches on instinctual shooting methods. Here is a link.

I am firm believer in self help on this and if you want to shoot better you should read at least first part of book and then practice on the footwork, gunmount and so forth. Anyway I had Todd Rogers standing behind me a watched me shoot and bust 25 straightaway targets and he said good job but your doing it wrong. He broke it down for over two days and then when I went and read the book light really came on. I taught my two boys how to shoot off my experience and used that book as basis and they are pretty good shots. There are a few other good books on it but this one is fairly short and to the point and throws a lot out. Maybe even good to go back and read some sections to remind yourself when you start doing things wrong.
