You can purchase 22 Long Rifle Snap Caps. A-Zoom makes and sells them (red aluminum/alloy). Oh I don't know about Australia though. Well I have Snap Caps for all my different calibers. It makes Dry Firing all my rifles,shotguns and handguns a more comfortable experience. Especially my older firearms.Also I have found that since I've started Dry Firing on a consistent basis a few years ago my ability as a shooter has improved.
