Who is the S&B Sellier & Bellot 45-70 Government Unprimed Brass Cases 20 Pack for?

• Big-game hunters targeting Australian scrub bulls, water buffalo, and feral boar — requires the 2.105 in (53.47 mm) nominal case length and straight-wall capacity of this unprimed rifle brass case to handload heavy 300-grain to 405-grain projectiles for close-range stopping power.
• Shooters developing precision loads for modern lever-action rifles, single-shot falling blocks, and vintage actions — utilizes the Boxer Large Rifle primer pockets in this 20-pack of brass cases to safely tailor pressure tiers to specific action strengths, from 18,000 PSI vintage ceilings up to 40,000 CUP modern limits.

Less suitable for: Shooters requiring hunting capabilities beyond a 200–250 metre effective working range, where high-velocity, bottle-necked rifle cartridges (such as .308 Win or .30-06 Springfield) are better suited; nor can these cases be chambered in alternative big-bore lever-action calibres such as .444 Marlin, .450 Bushmaster, or .458 Win Mag.
