A detailed guide on using 12-gauge Lockbuster rounds for high-speed, high-impact door breaching in military and law enforcement operations. Covers target points, techniques, equipment, and safety considerations.
* Overview: What is Ballistic Breaching?
Ballistic breaching is a rapid entry technique that uses 12-gauge breaching rounds to destroy locking mechanisms and door hinges during forced entry. This method is commonly used by military special operations forces and law enforcement tactical teams.
One of the most widely adopted munitions in this method is the Lockbuster round.
Lockbuster Round: Description and Types
The Lockbuster is a specially designed 12-gauge, 2.75-inch breaching round engineered for defeating doors and barriers. It comes in three configurations (A to C) based on target difficulty—light to heavy.
Model C is the military-grade round used by U.S. Naval Special Warfare teams.
* Construction
Projectile: A steel core encased inside a rubber pouch, further enclosed in a reinforced plastic cap.
Upon firing, the cap and pouch are expelled as a unit.
On impact, kinetic energy transfers into the target, destroying the lock or hinge without deep penetration.
Weapon Platform: Tactical Shotgun for Breaching
The breaching platform is a pump-action or semi-auto shotgun chambered in 12-gauge, purpose-built or modified for breaching.
* Standoff Distance
Recommended standoff: 0 to 2 inches (0–5 cm)
Optimal: 0 inches (muzzle contact), to reduce movement and deflection.
Note: Muzzle contact may not be possible near tight corners, doorknobs, or strike plates.
* Target Points and Impact Zones
- Doorknob & Strike Plate (Primary Target)
- Aim just behind the strike plate, where the latch bolt inserts—typically the weakest structural point.
- Shotgun should be leveled and held at a 45° horizontal angle.
- Expect to fire two rapid successive rounds.
- Avoid using sights—they cause aiming deviations in close quarters.
___
- Hinges (Secondary Target)
- Typically secured with 3–4 screws.
- Strike from top to bottom for best results.
- Breaching position:
- Upper hinge: one hand-width from door top.
- Middle hinge: approximately one hand-width above doorknob.
- Lower hinge: boot-height from the ground.
- Maintain a 45° horizontal angle; stay level with the target.
- May not be able to shoulder the stock when breaching high hinges.
_____
* Engagement Technique: 7 Key Rules
- Train with your support hand.
Enables door breaching while keeping your body protected by wall/doorframe.
- Keep the shotgun level with the target.
Angled shots can miss or hit unintended parts.
- Maintain a 45° horizontal angle.
Enhances lock or hinge destruction, especially in wooden doors.
- Do not use sights (iron or optics).
Remove or fold them if possible. Rely on muzzle alignment.
- Always be ready to follow up with a second shot.
- Do NOT enter with the shotgun as your primary weapon.
After breach, step aside immediately and allow the entry team to move.
- Chamber a new round immediately after each shot.

* Advantages of Ballistic Breaching
✅ High readiness:
No setup required like explosives; carried and used by the breacher instantly.
✅ Simple training curve:
Shorter training time compared to mechanical or explosive breaching.
✅ Speed at the breach point:
Faster than most alternate methods in dynamic entries.
✅ Multi-target capacity:
Carries enough rounds for multiple unknown entry points during missions.
✅ Can be used defensively if met with hostile contact post-breach.
* Limitations and Risks
- Risk to hostages or non-combatants: Shrapnel from locks, hinges, or wood splinters can cause serious injury.
- Over-penetration: If not aligned properly, rounds may penetrate through doors or walls.
- Vulnerability of the breacher:: Breacher is exposed to side fire or crossfire from within the room or hallway.
_____
Conclusion
Ballistic breaching with the Lockbuster round is an efficient, reliable, and battlefield-tested technique for forced entry, but it requires precision, control, and proper tactical sequencing.
It should be employed only by trained breachers who understand both the physical mechanics of door structures and the combat dynamics of entry scenarios.
Train Hard. Breach Smart. Dominate the Entry.
