“This drill is an old chestnut among some shooters but I hadn’t heard it before. Goes like this. Get yer gear and yer sighted-in serious gun, go to the range, set yer target, get in position, aim and fire one shot. You’re done. Don’t touch that dial, nudging zero is a whole different exercise. This is a ‘know thyself’ thing. Mark yer target and go home.
Do this over time, every weekend or every other day, or what ev-ver, no matter the weather: rain and misty, cold and windy, or warm and still. Whether yer rested or groggy. The idea is, a follow up shot may matter, or not, but the first shot will always matter. And you won’t get to pick the weather.” – Ol’ Remus in Yer Ol’ Woodpile Report
