The A-Zoom Action Proving Dummy Round / Snap Cap .300 PRC (part number 12315) is a precision-machined training aid designed to protect rifle firing mechanisms and support safe firearm handling drills. CNC-machined from solid aluminium with a hard-anodised finish, each inert round matches exact standard .300 Precision Rifle Cartridge dimensions to facilitate realistic chambering, magazine feeding, and extraction without live ammunition. The integrated synthetic polymer "Dead Cap" primer insert absorbs the direct impact of the firing pin, relieving stress on internal springs and pins during dry-fire practice or prior to long-term storage.

Key Features

  • Firing Pin Protection: Features a resilient polymer Dead Cap primer insert designed to absorb striking energy across more than 3,000 dry-fire strikes.
  • Precision Action Proving: CNC-machined aluminium dimensions match .300 PRC specifications for smooth cycling, feeding, extraction, and diagnostic function testing.
  • Durable Anodised Construction: Hard-anodised aluminium body resists wear during repetitive bolt-action manipulation and instructional training drills.
  • Safe Handling & De-Cocking: Enables safe uncocking of bolt-action rifles to relieve firing pin spring tension during storage without chambering live rounds.
