Can I use the Sellier & Bellot 5.3 LP Large Pistol Primers in rifle cases since they share the same 5.3 mm diameter?

No, you should never use these pistol primers in Large Rifle cartridges. Although both primer pockets measure 5.3 mm in diameter, rifle primer cups are thicker and deeper to withstand chamber pressures exceeding 50,000 psi, whereas pistol cups are softer and thinner and could cause dangerous ruptures under rifle pressures.

Are these primers suitable for high-pressure heavy magnum loads using slow-burning powders?

While S&B lists suitability for heavy handgun calibres like .44 Remington Magnum and .460 S&W Magnum, these are standard non-magnum formulation primers. If you are using heavy slow-burning powder charges like H110 or Win 296, or shooting in extreme sub-zero conditions, reloaders generally recommend dedicated magnum primers for reliable brisance.

What are the legal requirements for purchasing reloading primers in Australia?

Because primers are classified as Class 1.4S Dangerous Goods (Explosives) in Australia, purchasing them requires a valid firearms licence. Due to transport regulations, they cannot be shipped via standard Australia Post parcel networks and must be collected via pickup or specialised dangerous goods courier freight.

How should I store these 1,000-pack S&B primers to ensure long-term shelf life?

For optimal longevity and to prevent primer degradation over prolonged storage cycles, you should keep the 1,000-count pack in a cool, dry place. Standard storage thresholds recommend keeping them under 25°C with low relative humidity, away from direct heat sources and moisture.
