The metal door shook again.
Harder this time.
Dust fell from the ceiling of Bobby's storage locker as the creature slammed itself against the outside wall.
Ben tightened his grip on the shotgun.
"Dean, I'm gonna be honest…"
Another violent impact echoed through the room.
"...I liked it better when we didn't know ancient nightmare creatures existed."
Dean ignored him.
His eyes were fixed on Bobby's letter.
Reading fast.
Searching.
The creature scratched slowly across the metal outside.
Like it was listening.
Dean finally spoke.
"Bobby says the Colt can still hurt certain creatures even without the original bullets."
Ben blinked.
"How?"
Dean grabbed the small box of symbols from the crate.
Inside were strange engraved markings burned onto thin pieces of silver.
Sigils.
Bobby's handwriting covered the inside lid.
Emergency ritual rounds.
Ben frowned.
"That sounds dangerously improvised."
Dean smirked slightly.
"That's basically hunting."
Another slam hit the locker door.
This time a claw punched partly through the metal.
Ben jumped back.
"Dean!"
Dean quickly opened the cylinder of the Colt.
Empty.
He grabbed a normal revolver bullet from a nearby shelf.
Then pressed one of the engraved silver sigils against it.
The symbol burned bright orange for a second—
And fused itself into the bullet casing.
Ben stared.
"Okay… that's actually kinda awesome."
Dean loaded the round into the Colt.
CLICK
The creature slammed against the door again.
The hinges bent inward violently.
Dean spun the cylinder shut.
The sound echoed beautifully in the small room.
Ben looked at him.
"Tell me that works."
Dean raised the Colt slowly.
A faint smile appeared.
"Only one way to find out."
The creature roared outside.
Then the metal door exploded inward.
The shadow creature lunged into the locker in a storm of smoke and claws.
Its glowing white eyes locked onto them instantly.
Ben fired first.
BOOM
The shotgun blast staggered it—
But didn't stop it.
The creature screamed and rushed forward again.
Dean stepped toward it calmly.
The Colt raised in his hand.
For one brief second—
Everything felt still.
Like the world itself recognized the weapon.
Dean pulled the trigger.
BANG
The sound was deafening.
Different from any normal gunshot.
The sigil bullet hit the creature directly in the chest.
Light exploded from the impact.
The creature screamed.
Not in anger.
In pain.
Real pain.
Cracks of glowing orange spread across its body.
Smoke poured violently from its skin.
Ben stared in disbelief.
"No way…"
The creature stumbled backward, slamming into shelves.
Dean cocked the hammer again.
The shadow monster looked afraid now.
Actually afraid.
Dean smirked.
A very Winchester smirk.
"That got your attention, huh?"
The creature screeched one final time—
Then burst apart into black ash.
Silence.
The room went still.
Only the faint smoke drifting through the air remained.
Ben slowly lowered the shotgun.
Then looked at Dean.
Then at the Colt.
Then back at Dean.
"…Okay."
He pointed at the revolver.
"That is officially the coolest thing I've ever seen."
Dean looked at the Colt in his hand.
The ancient engravings reflected softly in the dim light.
For the first time—
He understood why hunters talked about it like it was a legend.
Ben walked closer.
"So Bobby figured out how to remake the bullets?"
Dean nodded slightly.
"Not exactly."
He handed Ben the letter.
Ben read the next line out loud.
"The ritual bullets are weaker than the originals… but they can still wound things that shouldn't exist."
Dean's expression hardened.
"Including whatever escaped the Gate of Ash."
Ben looked up slowly.
"…You think that thing was connected to the gate?"
Dean looked toward the destroyed doorway.
The ashes of the creature still smoked on the floor.
Then quietly:
"I think that was just the beginning."
Thunder rolled outside again.
Dean looked down at the map Bobby had left in the crate.
One location had been circled in red ink.
An old abandoned foundry.
And written beside it—
Original forging site.
Ben noticed it immediately.
"…Dean."
Dean folded the map carefully.
Then spun the Colt once before sliding it into his jacket.
A faint smile appeared.
"Looks like we're making bullets."
Outside the storage building…
Something watched the Impala from the shadows.
And this time—
It wasn't alone.
