Fast bolt excellent comment.
No one discussed dry firing. My instructors, SSG Schongert and SFC Reed insisted on 10 dry fires for every live round. Good mechanics, call your shot and stand clear of Rattle Battle type sessions.
When training I mentally asses my target, mentally go through the steps to draw, acquire the target and release the bullet.
I then go through the actual firing. Following the shot I asses the action of the weapon during the process and call my shot. I check the target to determine what actually happened. Once i have determined what actually happened I determine what corrective action needs to be taken to correct my faults and repeat the process.
An hour training session will result in shooting 20 to thirty rounds.
In short quality training trumps quantity training every time.
