RCBS 09578 Small Primer Pocket Brush - Stainless Steel Bristles

The RCBS 09578 Primer Pocket Brush delivers precise cleaning for small primer pockets across multiple calibers. This specialized reloading tool removes carbon buildup and debris that can interfere with proper primer seating and consistent ignition.

What Makes This Different

Stainless steel bristles resist corrosion and maintain their cleaning effectiveness through thousands of uses, unlike standard brass brushes that wear down quickly. The brush head diameter matches small primer pocket specifications exactly, ensuring thorough cleaning without enlarging the pocket. Professional reloaders choose stainless steel construction for its durability and consistent performance across various powder residues and environmental conditions.

Key Features

• Stainless steel bristles resist corrosion and maintain stiffness over extended use
• Small primer pocket specific design fits .175" diameter pockets precisely
• Compatible with popular small primer calibers including .223 Rem, .308 Win, 9mm, .40 S&W
• Ergonomic handle provides secure grip during repetitive cleaning operations
• Bristle configuration removes carbon deposits without damaging pocket walls

• Compact size allows easy storage in reloading bench drawers

Consistent primer pocket preparation directly impacts ignition reliability and accuracy potential. Carbon and powder residue accumulation creates uneven primer seating depths, leading to pressure variations and velocity spreads. Competition shooters and precision reloaders rely on thorough pocket cleaning to maintain single-digit extreme spreads. The stainless steel bristles cut through stubborn deposits that softer materials leave behind.
