Dry fire practice makes the difference when you need to burn in a new skill or can't get out to the range. You can improve all of the shooting basic skills in dry fire or at least maintain you current level. Dry fire and live fire are separate activities in a shooting pro-gram. Tests have shown that shooters that are trained by dry firing first have fewer bad habits and score better than shooters that just practiced on the range. Obtain the benefits of both and you will enjoy the best training program.
Dry fire can get boring and old.
Change it around, practice different skills, and come up with new exercises to keep it interesting. There are many different ways to practice in your own home that don't cost any money. Try all the exercises in this book and work on them until they are second nature. If you dry fire every day for at least 15 minutes you will enjoy improvement in your overall shooting. I don't know anyone that can't find 15 minutes in their schedule.
