well try only having 1 eye lolI was taught "BRASS". Breathe, Relax, Aim, Slack (as in take up), Squeeze.
I also like to blink a few times to moisturize my eyes & help the focus, my eyes are not getting any younger.
have studied and taught many classes in shooting
many ppl have many stiles so my question is how do you breath when you shoot
sounds dumb but trust my proper breathing helps
