That is a good idea. I am have only tested my dead shot time, and it is no where near the distances I practice dry fire. I just started testing my dead shot times a couple days ago at about 10 yards on a full size IDPA targed. My times are similar (best being a .72) and hits are center mass. I haven't done much live fire drills by myself, I usually save my ammo for the matches. What is a good ratio of live fire to dry fire using the same drills?
