I have thought about the use and value of log books over the years. I use it to learn my rifle but I only use the detailed log book at the range. In the real world I take cheat sheets with distilled proven data.
I assume that gadgets will get broken and lost, stomped or drowned- but of course folks could say the same for log books and cheat sheets.
I am ALWAYS looking for elegant simplicity and a better way of doing it.
I always stayed away from Load Specific cranky knobs because things change.
I wish there were more MOA reticles and Knobs instead of Mil/Mil but hey... there you go, military is a meter/metric kind of world. What is it??? The tangent of one miliradian is .001 or something making the math simpler.
Traditionally the military has used mil reticles and MOA turrets. I used MOA reticle and turrets when I started out but have since switched to mil/mil either one works but I have found that I like mil/mil better
