Are these S&B .204 Ruger brass cases primed or unprimed, and what size primers do they require?

These S&B Sellier & Bellot cases are supplied completely unprimed and feature a standard Boxer primer pocket. They specifically require Small Rifle primers for your handloading process.

What primer pockets and pressure limits should I keep in mind when reloading these .204 Ruger cases for varmint hunting?

These brass cases are engineered to withstand standard SAAMI and C.I.P. maximum average pressure limits for the .204 Ruger, which is approximately 57,000 to 58,000 psi. Exceeding these limits in your handloads can lead to loose primer pockets or case-head separation during extended outback pest control sessions.

Do I need a specific firearms licence to purchase these unprimed brass cases in Australia?

Yes, while unprimed brass cases are inert metallic reloading components rather than complete ammunition, state and territory firearms acts across Australia still regulate their possession. Customers generally must hold an appropriate firearms licence or permit covering Category A or B longarms to purchase them.

Can I use these cases for medium-to-large game hunting like deer or pigs?

No, the ultra-light .204 bore is purpose-built for small predators, varmints, and target shooting out to 300 to 400 metres. Ethical hunting regulations and practical performance dictate that medium-to-large game such as fallow deer, red deer, or pigs require heavier calibres like .243 Win or .308 Win.
