FROM THE FIELD
Shooters who stopped doing math.
"First match with it, I stopped writing dope on my arm. Range, dial, send - the stage clock stopped being my enemy."
"Ranged a bull at 611 in a crosswind at 9,400 feet. The correction was money. One shot, short tracking job."
"I teach fundamentals; TrueArc removes the arithmetic. Students are making first-round hits at 800 on day one."
