Swift High Grade 6.5×55 Swedish Mauser ammo with the 140-grain A-Frame bonded round nose is a purpose-built big-game load for hunters who demand terminal performance in timber, brush, and bone. The 6.5×55 Swedish Mauser cartridge — a mild-recoiling, flat-shooting European classic — pairs with Swift’s signature bonded-core design to produce controlled expansion and deep straight-line penetration on elk, moose, bear, and heavy-bodied deer at typical hunting ranges.

Built for the Box

Each round in this 20-count box begins with once-fired brass cases that meet or exceed SAAMI dimensional tolerances. Swift individually chambers and sizes every case, then applies Hernon water-tight sealant to primer pockets and case mouths. The 140-grain A-Frame bullet features a cross-member copper jacket bonded to a pure lead front core and a heavier rear core. That design drives 95% weight retention and resists core-jacket separation even after striking heavy bone or angled shots through shoulder.

Performance at a Glance

The A-Frame’s semi-spitzer round nose profile reduces felt recoil in the magazine and feeds reliably in controlled-round-feed Mauser actions. Its 0.401 ballistic coefficient and 0.287 sectional density produce flat trajectory and wind-bucking momentum suitable for shots inside 300 yards. Brass cases accept standard large-rifle primers and reload cleanly. You’ll find this load equally at home in vintage Swedish Mausers, modern bolt rifles, and single-shots chambered in 6.5×55 ammo.
