Who is the S&B Sellier & Bellot 308 Win Unprimed Brass Cases 20 Pack for?

• Handloaders seeking 308 Winchester reloading components — requires virgin .308 Winchester cartridge brass fitted with standard Large Rifle Primer pockets to assemble custom-tailored ammunition ladders.
• Hunters and target shooters handloading custom 308 Win loads in small batches — benefits from a compact packaging allocation of 20 pieces per bag to develop and test specific projectile and powder combinations without committing to high-volume brass runs.

Less suitable for: High-volume target shooters needing more than 20 cases at a time, who are better served by bulk 100-count or 500-count brass bags, as well as benchrest and extreme long-range competitors requiring specialised match-grade brass cases with drilled flash holes and factory-sorted weight tolerances.
