Browning X-Bolt Short Action Black Polymer Rotary Magazine - Fits .270 WSM, 7mm WSM, .300 WSM, .325 WSM

The Browning X-Bolt Short Action Black Polymer Rotary Magazine is a purpose-built replacement magazine for WSM hunters running Browning's X-Bolt platform. If you shoot .270 WSM, 7mm WSM, .300 WSM, or .325 WSM, this detachable rotary mag delivers the feed reliability and straight-line cartridge presentation that makes the X-Bolt system so dependable in the field. Whether you're building a backup magazine stack or replacing worn components, this polymer design gives you the same direct-feed geometry that makes your rifle shoot.

The rotary magazine's defining feature is its feeding path: cartridges feed directly in line with the bolt rather than offset as with traditional leaf-spring designs. That straight shot into the chamber means fewer jams, smoother cycling, and the kind of mechanical simplicity that matters when conditions get harsh. The lightweight polymer construction keeps weight down without sacrificing durability, and an ergonomic magazine-mounted release makes mag swaps fast and intuitive—no fumbling for a catch on the receiver.

Capacity depends on your caliber: magnum loads (.300 WSM, .325 WSM) hold three cartridges, while standard WSM rounds (.270 WSM, 7mm WSM) give you four. This engineering reflects real-world physics—larger case volumes mean fewer rounds fit in the same footprint. The design is covered by U.S. patents, reflecting Browning's investment in feeding reliability that competitors haven't matched.

If you already trust your X-Bolt rifle, this magazine is a natural fit—no guesswork, no conversion kits, just Browning engineering made for Browning rifles.

Frequently Asked Questions

Which X-Bolt models and calibers does this magazine fit?

This magazine is designed for Browning X-Bolt rifles chambered in .270 WSM, 7mm WSM, .300 WSM, or .325 WSM. Confirm your rifle's caliber before ordering—WSM designations are caliber-specific.

How many rounds does it hold?

Capacity is three cartridges for magnum WSM calibers (.300 WSM, .325 WSM) and four for standard WSM loads (.270 WSM, 7mm WSM). Case volume determines the difference.

What's the advantage of a rotary magazine over a standard leaf-spring design?

The rotary design feeds cartridges directly in line with the bolt path instead of offset, creating a straighter, more reliable path into the chamber. This reduces feeding issues and improves overall reliability, especially under rough field conditions.

Is this a replacement magazine or does it come with a rifle?

This is a detachable replacement magazine sold separately. It's ideal as a backup magazine or as a replacement for an original Browning X-Bolt magazine.
