I was thinking about everything I do when that last moment comes while squeezing the trigger. This is a rifle I am talking about. My breathing control, cheek weld, sight picture thru the scope, finger pressure. While I wait for the shot I notice my heart beat is affecting the sight picture thru the scope. How do you compensate for that? How long between when you slowly release your breath and round fires? What if a gust of wind comes up and you hesitate to take the shot? Doesn't that mess up the timing of everything? How do you get mentally prepared before shooting? Do you visualize before hand every step that occurs? What about getting into the zone where everything else not important is blocked out? I am sure there is somethnig else I am leaving out, but I have been thinking alot about this. Are there any good books about this? Any advice from members?
