One thing that has really grabbed my attention recently about shooting precision. After nearly a year out of the country and doing no shooting at all, my rifles all seem to have less than half the accuracy they used to.
The lesson is this: the biggest variable in shooting precision is the shooter. Biological systems (people) will never remotely achieve the precision of the mechanical/chemical system that is a firearm. As much as the obsessive-complusive hyper-nerd part of me wants to fix all things by fixing "things", what I really need to tweak is myself. Breathing, relaxation, concentration, training muscle memory. Terribly Zen...enough to be on the edge of my comfort zone. I need to find a culturally palatable shooter version of yoga, I think.
