Why Choose Bertram .300 Rook?

  • Imported and supported in the United States by Desert Tech Munitions

Cartridge Overview

The .300 Rook is a small British centerfire sporting cartridge associated with lightweight rook and rabbit rifles of the late nineteenth and early twentieth centuries. These compact rifles were used for pest control, informal target shooting, and small-game hunting on estates and farms.

Rifles and Platforms

  • British rook and rabbit rifles specifically chambered for .300 Rook
  • Light single-shot and break-action sporting rifles with a verified matching chamber

Compatibility warning: Historic cartridge; verify the exact chamber and bore of the individual rook rifle. Similar names, shared caliber, or external resemblance do not establish interchangeability.

Legacy & Context

Rook rifles represent a distinctive British sporting tradition: finely made, lightweight rifles for modest centerfire cartridges. Surviving examples are now valued by collectors and careful handloaders.

Did You Know?

Royal Armouries records a .300 Rook specimen as a rimmed, straight brass centerfire cartridge. Similar small British cartridges are not interchangeable solely because their case shapes appear alike.

No. This listing is for new, unprimed brass cartridge cases only.

Will it fit a firearm with a similar cartridge name?

Not necessarily. Verify the complete chamber designation and the individual firearm before ordering.

Yes. Inspect every case and perform the preparation appropriate to the chamber, dies, projectile, and loading process.

Why is this product sometimes difficult to find?

Demand is specialized, so Bertram generally manufactures it in scheduled batches rather than continuously.
