The A-Zoom 10 Gauge Aluminium Snap Caps (Model 12210) are precision-engineered training rounds designed to protect shotgun firing mechanisms during dry-fire practice and action cycling. Precision CNC-machined from solid aluminium to exact 10 Gauge SAAMI shotshell dimensions, these inert caps feature a hard-anodised finish to eliminate rim chipping and flaking during repeated feeding, extraction, and ejection drills. Each cap incorporates A-Zoom’s synthetic polymer "Dead Cap" primer insert, which absorbs the kinetic impact of the firing pin to prevent damage to internal springs, firing pins, and sears. Supplying a total packaged weight of approximately 110–130 g, this 2-pack provides realistic handling and weight distribution for safe gun manipulation and long-term storage spring relief without the use of live ammunition.

Key Features

  • Dry-Fire Protection: Incorporates a synthetic polymer Dead Cap insert engineered to cushion the firing pin strike and prevent sear, spring, or pin breakage.
  • Extended Service Life: Primer insert is rated to withstand over 3,000 dry-fire strikes per cap, outlasting traditional plastic dummy rounds by up to 30 times.
  • Precision Machined Aluminium: Solid CNC-machined aluminium body with a hard-anodised surface resists deformation, flaking, and rim wear across continuous extraction cycles.
  • Realistic Handling: Machined to exact 10 Gauge SAAMI dimensions to facilitate functional testing, smooth cycling, loading practice, and safe uncocking before storage.

Who is the A-Zoom 10 Gauge Aluminium Snap Caps - 2 Pack for?

  • 10 gauge shotgun owners practising dry-fire trigger control — Engineered specifically for dedicated 10 Gauge shotgun chambers to absorb over 3,000 dry-fire strikes per cap using a polymer Dead Cap that prevents firing pin and mainspring damage during repetitive trigger-pull practice.
  • Fowler maintenance and gunsmithing action testing — Supplied in a 2 Pack of CNC-machined aluminium 10 gauge shotgun snap caps that replicate exact SAAMI chamber dimensions to safely test extractor, ejector, and feeding function without risk of live discharge.

Less suitable for: Owners of 12, 16, 20, 28, or .410 bore firearms, or training applications where units exceed 3,000 dry-fire strikes and exhibit deep polymer pocket indentation; these applications require gauge-specific snap caps or replacement inert dummy rounds.
