The .22 Rimfire Action Proving Dummy Rounds by AZoom (sold under the Pachmayr Snap Caps branding) are precision-engineered for function testing, training, and safe handling. CNC-machined from solid aluminum and hard anodized for ultra-smooth operation, these dummy rounds replicate the exact dimensions of .22 LR cartridges. Unlike disposable plastic snap caps, they offer long-term reliability suitable for action cycling, magazine testing, and educational use. Although not ideal for repeated dryfire impact, they deliver consistent performance as proving rounds to safeguard firing pins and mechanics. A-Zoom .22 Rimfire dummies are widely used for hunter education and teaching safe firearms handling. Gunsmiths rely on them, too. When checking or adjusting the trigger pull use snap caps. Key Points Precisely machined to match .22 LR cartridge dimensions Hard anodized aluminum construction for smooth cycling Designed for action testing and function drills (not dry-fire protection) Highly durable and reusable for multiple loading/unloading cycles Ideal for hunter education, gunsmith testing, training scenarios Distinct from snap caps-focuses on function proving, not impact dampening WARNING: A-Zoom 22 Long Rifle Action Proving Dummy Rounds are designed to teach safe firearms handling. They are not snap caps. They may be worked through the actions of any 22 Long Rifle for function testing. Dry firing will deform the head and will limit their use to 4 or 5 hits. Specifications Material: CNC-machined aluminum, hard anodized Caliber: .22 Long Rifle Pack Sizes: Available in packs of 6, 12, or 20 rounds Color: Natural anodized finish or orange (modeldependent) Weight: Approximately 18g per 6pack package (~0.02kg) :contentReference[oaicite:1]{index=1} Package Dimensions: ~6.06x4.25x0.51 (for 6pack) :contentReference[oaicite:2]{index=2} Usage Context These dummy rounds are perfect for firearm instructors, gunsmiths, competition shooters, or youth education programs needing safe but realistic cycling without firing pin strikes. They facilitate proper loading/unloading drills, magazine function testing, and trigger pull evaluated in dry-run scenarios. Comfort & Fit With exact ammo-like dimensions and smooth anodized surfaces, each dummy round chambers and ejects precisely in most .22 LR rifles and pistols. They fit magazines and chambers like live ammo, offering realistic handling without live-fire risk. Technology & Materials Manufactured from solid aluminum billet using CNC machinery and finished with a hard anodize coating, these rounds resist wear and maintain shape over repeated use. They are not engineered with a false primer-dry-firing may deform them and reduce their lifespan after limited impact use :contentReference[oaicite:3]{index=3}. The .22 Rimfire Action Proving Dummy Rounds offer shooters a reliable, dimensionally accurate tool for function testing and training. While not intended to replace true snap caps for drop protection, their precision and durability make them ideal for safe handling exercises and mechanical checks.
