Marksmanship Fundamentals & Ballistics Flashcards

When diagnosing a student who consistently shoots high and right (right-handed shooter), the MOST likely cause is:

Answer: Thumb-heeling — pressing the thumb of the shooting hand toward the target during the trigger press

Thumb-heeling, where the shooter pushes with the strong-hand thumb to compensate for anticipated recoil, drives shots high and to the dominant side.

Which of the following BEST defines the 'natural point of aim' (NPA) in handgun training?

Answer: The direction the handgun points when the shooter's body is relaxed and aligned, without muscular correction

Natural point of aim is where the firearm naturally points when the shooter is fully relaxed, and building stance around NPA reduces muscle fatigue and improves consistency.

What is the Isosceles stance in handgun shooting and what is one key benefit it provides?

Answer: A two-handed stance with both arms extended equally forming a triangle; it provides natural pointing and is easy to learn under stress

The Isosceles stance uses equal arm extension forming a triangle shape and is widely taught because it is intuitive, recoil-managing, and easy to default to under stress.

What does 'headspace' refer to in the context of handgun ammunition and chamber safety?

Answer: The distance from the bolt or breech face to the datum line in the chamber where the cartridge headspaces; improper headspace can cause dangerous pressure issues

Headspace is the critical chamber measurement that determines proper cartridge seating; incorrect headspace can cause case ruptures, misfires, or catastrophic failures.

An instructor observes that a student's brass is ejecting straight back and hitting the shooter in the face. This pattern typically indicates:

Answer: The ammunition may be slightly under-powered, causing the action to cycle slower than designed (limp-wrist or underpowered ammo)

Brass ejecting rearward rather than to the side typically results from a slow cycling action caused by underpowered ammunition or a limp-wrist grip that absorbs cycling energy.

What is the primary purpose of teaching the 'compressed surprise break' trigger technique to handgun students?

Answer: To apply increasing, smooth pressure on the trigger so the shot fires without the shooter knowing the exact moment, preventing flinch

The compressed surprise break keeps the shooter from anticipating the shot by building trigger pressure smoothly until the gun fires, eliminating flinch-induced accuracy errors.
