Winchester WSC6555SU 6.5x55 Swedish Unprimed Brass Cases 50/Bag

Winchester WSC6555SU unprimed brass cases deliver the precision foundation serious 6.5x55 Swedish handloaders demand for match-grade ammunition. These cases undergo Winchester's multi-stage manufacturing process to ensure consistent wall thickness and optimal primer pocket dimensions. Handloaders gain complete control over powder charges, bullet seating depth, and overall cartridge specifications when starting with quality unprimed brass.

What Makes This Different

Winchester brass cases feature uniform wall thickness achieved through precision drawing and annealing processes that exceed military specifications. The brass composition maintains optimal hardness for multiple reloading cycles while preventing case head separation or neck splitting. Each case undergoes dimensional inspection to ensure SAAMI specifications are met, delivering the consistency required for long-range precision shooting.

Key Features

• 6.5x55 Swedish chambering with SAAMI-spec dimensions for universal rifle compatibility
• Unprimed cases allow custom primer selection for specific powder and bullet combinations
• High-quality brass alloy rated for 8-10 reloading cycles with proper case preparation
• Consistent case capacity within 0.5 grains for uniform ballistic performance
• Factory-fresh brass eliminates case preparation steps required with military surplus
• 50-case count provides sufficient quantity for load development and testing
• Compatible with standard reloading dies from RCBS, Redding, Hornady, and Lee

These cases perform reliably across temperature extremes and maintain dimensional stability through multiple firing and sizing cycles. Competition shooters appreciate the consistent internal capacity that eliminates velocity variations between rounds. Hunters benefit from the ability to tailor loads for specific bullet weights and hunting scenarios, from 120-grain varmint bullets to 160-grain big game projectiles. The 6.5x55 Swedish cartridge's moderate pressure levels extend case life compared to magnum calibers.
