Chapter 6
I didn’t try to track the pin. I didn’t try to follow its erratic, dancing movement through the mirage. Instead, I calculated the rhythm of the oscillation. I found the center point of the distortion—the place where the physical pin actually existed beneath the illusion created by the heated air.
I moved the crosshairs away from the pin. To the untrained observer, it would have looked like I was aiming completely into empty space, pointing the rifle several feet above and to the left of the entire structure. I was aiming at nothing but a patch of barren, sun-baked desert rock.
But I knew the math. I knew the flight path. I knew that during the three seconds that bullet spent traveling through the sky, the twenty-eight-knot crosswind would drag it hard to the right, and the heavy thermal updraft from the canyon floor would lift it like a glider before gravity finally claimed its toll.
I let out the breath. My body went completely cold. My heart rate dropped into a slow, rhythmic thudding that seemed to synchronize with the movement of the universe.
My index finger slid into the trigger guard, making light contact with the cold, curved steel of the match-grade trigger. I didn’t pull it. I didn’t jerk it. I simply began to apply a slow, microscopic increase in pressure, letting my mind detach itself from the physical act of shooting.
The world narrowed down to a single point of absolute stillness.
BOOM.
The McMillan TAC-50 exploded with a violence that shook the very bedrock beneath my body. A massive, concussive wave of overpressure blasted outward from the muzzle brake, tearing through the air and sending a violent shockwave across the concrete pad behind us. The dust cloud that erupted around the front of the rifle was instantaneous, a thick, gray wall of pulverized earth that completely blocked my vision.
The heavy recoil slammed into my right shoulder with the force of a sledgehammer, but my body didn’t move. I had locked my skeleton into the dirt, allowing the massive energy of the fifty-caliber round to pass through my frame and dissipate safely into the ground.
Without waiting to see the result, my right hand flew to the bolt handle. I slammed it up, yanked it back, and a large, smoking brass casing flew through the air, glinting in the harsh sunlight before bouncing into the gravel. I slammed the bolt forward, locking a fresh round into the chamber, my eye already locking back onto the scope as the dust cloud began to clear.
“Bullet is in flight,” Jackson whispered, his voice trembling with an intensity I had never heard before. “One second… two seconds…”
The silence on that ridge was heavy enough to crush a man. Nobody breathed. Nobody spoke. Twelve elite Navy SEALs stood perfectly frozen, their eyes locked on the distant valley, waiting for the verdict of a nineteen-year-old girl’s rifle.
Three seconds after the trigger pull, the distant landscape erupted.
Through the clearing mirage, I saw the exact spot where the heavy match-grade bullet struck. It didn’t hit the concrete. It didn’t hit the rock.
The massive, solid-brass projectile slammed directly into the center of the three-inch rusted steel pin with a catastrophic transfer of kinetic energy. The impact was so violent that a brilliant flash of sparks erupted from the metal, visible even through the thick dust of the valley.
The rusted pin shattered into a dozen jagged fragments under the immense force of the fifty-caliber round. The primary retaining wall, stripped of its critical structural anchor, gave way instantly. A massive section of old concrete and heavy masonry fractured along a pre-existing fault line, collapsing outward in a roaring avalanche of gray dust and heavy stones.
“Direct hit!” Jackson screamed, his voice breaking as he jumped to his feet. “Look at the wall! It’s coming down!”
The collapsing masonry fell precisely as I had calculated, tumbling down the slope away from the old bunker. A massive wave of heavy rock and broken concrete swept into the narrow ravine below the test pit, creating a dense, immovable barrier of solid debris right at the base of the sliding roof slab.
The three-ton concrete slab gave another violent lurch, sliding down the slope toward the child and the dog. But before it could reach them, the front edge of the slab slammed hard into the newly formed rockslide barrier.
A deep, hollow boom echoed across the canyon as the massive pieces of stone collided. The sliding slab shuddered, its momentum completely halted by the wall of debris. It groaned under the immense weight, then settled into the dirt, locking itself firmly into place less than twelve inches from where the German Shepherd’s front paws were dug into the gravel.
The structure was stable. The path to the test pit was completely blocked.
