A-Zoom .22 LR Training Dummy Rounds 6-Pack

These A‑Zoom .22 LR action‑proving dummy rounds are inert training cartridges intended for function testing, magazine loading practice, and safe‑handling drills. They are CNC machined from solid aluminum and hard anodized to .22 LR cartridge dimensions so they cycle in most rimfire actions. These devices are not live ammunition and are intended for non‑firing training and mechanical checks. Some source text uses the term “snap cap” while other source text explicitly calls them dummy/action‑proving rounds; see product notes below for details.
