Natural Point of Aim
• Find dominant eye
• Find comfortable position
  – 45 degrees is good start
  – Feet at shoulder distance
• Hand points at the center of the target
• Lock wrist and elbow

  – Consistent
       • Memorize how it feels
       • Non-shooting hand to adjust
Breath Control
• Hold breath while making the shot
  – Reduces body movement
• 8-10 seconds before losing visual acuity
• Take deep breaths to slow down heart-
  rate
• Take a breath while lifting the gun
• Let out small amounts of air to adjust
  vertical position
Sight Alignment
•   Demo with Sight Toy
•   Focus on the front sight with Dominant Eye!
•   Tops should be even
