How do you practice "shooting yourself in the head" rounds?
The BASICS, my friend, the basics.
Firm steady grip. Squeeze the trigger, don’t pull or jerk. (I guess we will have to forget sights). Be sure of your back stop.
Every time you go out to practice it is important to spend time on the basics.
A couple thousand rounds may be excessive, but we don’t know how long it has been cense he last practiced:)
