I know a ton of ways to add pressure on the range. Pro tip-Use a timer like in competition
Really want real? 1/10th serious here- Get a paramedic to the range. Run drills keep score. Get a shot of synthetic adrenaline and re run the drill. Epinephrine? It’s been done before but not (literally) for the faint of heart.
The result was a slight reduction in accuracy. Very slight.
