Bernie, with all due respect, there are so many others to glean shooting form information from than Pete Shepley. Probably first and foremost, Randy Ulmer. Randy has published many excellent shooting form articles over the years. On the tournament circuit in the 80s and 90s Randy was the man the rest of us chased, a better shooter I've never known. John Dudley likewise has written some very spot on shooting form material. If you want some old school, (which makes them no less of a shooter) Terry Ragsdale, Frank Pierson, George Chapman have all put out instructional material that is very good.
I shot for Pete's company in the late 80s and early 90s, wouldn't ask him to pass the salt at a dinner table. I have to thank him though, for reasons I wont get in to, many of us moved on and in 94 I was asked to join the Mathews team.
