I am a huge reader and I read a book by Lt. Col Dave Grossman that every gun owner, shooter needs to read. It is called "On Combat" this book contains the sheepdog article. That in itself is very profound but the rest of the book will have a very big impact on your life. Another book by his is "On Killing" this book was nominated for a pulitzer prize and is a study on lethal force. I highly reccomend both. Good reading Members!
