Browning X-Bolt 3rd Gen Rotary Magazine WSM Short Action Polymer

The Browning X-Bolt 3rd Generation Rotary Magazine transforms feeding reliability for Winchester Short Magnum cartridges. This factory magazine assembly eliminates feeding issues common with standard detachable magazines in magnum calibers, delivering consistent chambering across all four WSM cartridge types.

What Makes This Different

Unlike conventional detachable magazines that can struggle with the steep shoulder angles of WSM cartridges, this rotary design uses controlled cartridge presentation for smooth feeding. The polymer construction reduces weight by 40% compared to steel alternatives while maintaining structural integrity under magnum pressures. Factory engineering ensures precise fitment with X-Bolt short action receivers without modification.

Key Features

• Compatible with 270 WSM, 7mm WSM, 300 WSM, and 325 WSM cartridges
• Rotary feeding mechanism prevents cartridge nose diving and rim lock
• Black polymer construction resists corrosion and temperature extremes
• Factory Browning part ensures proper headspace and timing
• Drop-in installation requires no gunsmithing or modifications
• Lightweight design reduces overall rifle weight by 2.8 ounces
• Positive retention system prevents accidental magazine release

Field performance shows significant improvement in feeding reliability, particularly with heavy-for-caliber bullets that can bind in standard magazines. The rotary mechanism maintains consistent cartridge alignment during rapid follow-up shots, critical for hunting situations requiring quick second shots. Temperature cycling from -20°F to 140°F produces no feeding malfunctions or dimensional changes in the polymer housing.
