Pro-Shot Tornado Bore Brush — 12 Gauge Shotgun — #5/16-27 Thread — Brass Spiral-Wound Loop — Model 12STO (UPC 709779101115)
Keep your shotgun shooting reliably and accurately with the Pro-Shot Tornado Bore Brush 12STO, engineered specifically for 12-gauge shotguns. This professional-grade brass spiral-wound loop brush delivers aggressive yet bore-safe cleaning, removing lead, plastic wad residue, carbon, and powder fouling faster and cleaner than conventional brushes. If you want a spotless throat and consistent patterns, the Tornado design is a must-have in every shooter’s cleaning kit.
Why the Pro-Shot Tornado Brush Is the Best Choice for 12-Gauge Shotguns
The Tornado’s patented spiral-wound construction creates dozens of continuous, flexible cleaning edges that scour fouling from the entire bore surface while minimizing the risk of bristle breakage or metal-to-metal scoring. Made from high-quality brass filaments, the 12STO provides the ideal balance of cleaning aggressiveness and gentleness — tough on deposits but forgiving on plated, stainless, or chrome-lined barrels and chokes.
The looped end eliminates sharp wire ends that can damage the muzzle crown or pass through chokes, making this brush safer for repeated use and compatible with common choke designs when used carefully. Its robust build and consistent diameter retention mean longer service life and more cleaning cycles compared to cheap, low-quality brushes.
Key Benefits & Performance Features
Designed for 12-gauge shotguns: Optimal diameter and filament density target typical shotgun bore and chamber geometries.
Brass spiral-wound filaments: Aggressively remove lead, plastic wad, and carbon without shredding or leaving abrasive residue.
Looped safety end: Protects crown and choke; prevents sharp filament tips from contacting sensitive surfaces.
#5/16-27 standard thread: Compatible with most shotgun cleaning rods, handles, and adapters on the market.
Consistent construction: Spiral winding maintains uniform contact with the bore for even cleaning and faster results.
Durable & long-lasting: Brass resists corrosion and keeps its shape across many cleaning cycles.

How to Use for Best Results
Confirm fit: Ensure your cleaning rod or cable uses a #5/16-27 thread — matches the 12STO standard.
Apply solvent: Lightly saturate the brush or the bore with a quality shotgun solvent to loosen fouling.
Use controlled strokes: Push or pull the brush through the bore in steady, moderate strokes. Avoid rapid repeated hammering motions.
Follow with patches: Run solvent-soaked patches until they come out clean, then dry patches and a light protective oil.
Inspect and replace: Check the brush for flattening or loose filaments; replace when cleaning performance diminishes.
Compatibility & Accessories
Works with most #5/16-27 threaded shotgun cleaning rods, T-handles, flexible cables, and adapters.
Pairs well with copper, lead, and carbon solvents, bore paste for stubborn fouling, and Pro-Shot cleaning kits for a complete maintenance system.
Use with appropriate choke tools or by removing the choke where possible to avoid stress on constricted sections of the bore.
