A-Zoom Rimfire Action Proving Dummy Rounds 17 HMR 6-Pack

The A-Zoom Rimfire Action Proving Dummy Rounds in 17 HMR are precision CNC-machined from solid aluminum and finished with a hard anodized coating for long life and smooth functioning. Built as exact replicas of factory-loaded rimfire ammunition, these dummies match real cartridges in diameter, length, weight, and balance, making them an ideal tool for safe gun handling, dry fire practice, and action and function testing on rimfire rifles and magazines.

Unlike spring-loaded snap caps, A-Zoom's Action Proving rounds are precisely dimensioned, functional dummies that cycle through rimfire actions like live ammo, with no primers, powder, or projectiles. This 6-pack of 17 HMR training rounds gives you multiple dummy rounds for repetitive loading drills, magazine testing, or trigger-weight work on the bench or in the classroom.

Each round is cut from a single piece of aluminum and treated with a hard anodized finish for smooth feeding and extraction over thousands of cycles. Whether you are teaching a new shooter the basics of safe firearm handling, running a semi-auto or bolt-action through its paces, or simply checking the reliability of a 17 HMR rifle, the A-Zoom Rimfire Action Proving Dummy Rounds deliver realistic function without the noise, recoil, or expense of live ammunition.
