Will these A-Zoom 17 HMR dummy rounds work in my .22 LR or .22 WMR firearm?

No, these dummy rounds are precision-machined specifically for .17 Hornady Magnum Rimfire (.17 HMR) chambers and have an overall length of 26.67 mm. They are strictly incompatible with .17 WSM, .17 Mach 2, .22 LR, or .22 WMR platforms.

Can I use these solid aluminium rounds for high-volume dry fire trigger practice?

A-Zoom classifies these as action proving dummy rounds rather than dedicated snap caps. Because rimfire firing pins strike the edge of the rim directly, extended dry firing can cause rim indentation and firing pin wear over time, so they are best suited for feeding, cycling, extraction, and ejection drills.

Do I need a firearms licence to purchase or possess these training rounds in Australia?

No, because these are 100% inert metal training pieces containing zero primer, propellant, or explosive components, they do not require an Australian firearms licence or ammunition permit to buy or own in any state or territory.

How durable is the construction during repeated cycling in semi-automatic or bolt-action rifles?

Unlike soft plastic alternatives, these 6-pack rounds are CNC-machined from solid aluminium billet with a hard-anodised burgundy finish. This robust metal construction prevents chipping, deformation, or feed-ramp gouging through heavy handling drills.

.17 HMR Dummy Rounds - A-Zoom AZ17HMR

The A-Zoom .17 HMR Rimfire Action Proving Dummy Rounds are precision-machined inert cartridges designed for safe mechanical cycling, magazine feeding checks, and firearm handling drills without live ammunition. Manufactured from solid aluminium billet and finished with a durable hard-anodised coating, each dummy round matches exact SAAMI external dimensions to reliably simulate live ammunition handling in bolt-action, lever-action, and semi-automatic .17 Hornady Magnum Rimfire firearms. As completely inert, primerless metal units, these training rounds are fully legal across all Australian states and territories without requiring a firearms licence or ammunition permit.

Key Features

Safe Action Proving: Permits realistic loading, chambering, magazine feeding, extraction, and ejection testing without live propellant or primers.
Solid CNC-Machined Aluminium: Resists the rim chipping, deformation, and feed-ramp gouging common with soft plastic rimfire training rounds during repeated cycling.
Dimensional SAAMI Accuracy: Machined to authentic cartridge profiles to approximate the weight, balance, and feeding characteristics of standard .17 HMR live ammunition.
Training Utility: Provides a completely inert platform for hunter safety training, classroom weapon manipulation, and home loading/unloading drills.

Overall Length: 26.67 mm (1.05 in)

Who is the A-Zoom 17 HMR Dummy Rounds 6-Pack for?

Firearms Instructors — Needs completely inert training tools built to the authentic 26.67 mm overall length of .17 HMR ammunition to demonstrate safe loading and unloading mechanics during beginner firearm handling courses.
Hunters and Target Shooters — Requires a 6-pack of durable aluminium action proving dummy rounds to safely test magazine feeding and action cycling at home without introducing live ammunition.
Gunsmiths — Relies on precise SAAMI-dimensioned .17 HMR dummy rounds measuring 26.67 mm in length to diagnose action tolerances, chambering resistance, and ejection reliability on customer firearms.

Less suitable for: Shooters seeking high-volume dry-fire trigger practice or users of .17 WSM, .17 Mach 2, .22 LR, or .22 WMR platforms; repeated rimfire firing pin strikes on solid metal rims cause rim indentation and firing pin wear, making dedicated polymer rimfire snap caps or spent brass cases better suited for trigger-pull training.
