Frequently Asked Questions

What is the main difference between Weatherby's 9-lug and 6-lug Mark 5 rifle actions?

The primary difference lies in their physical dimensions and intended use. The 9-lug is a traditional, wider long action designed for a broad range of magnum cartridges. The 6-lug is a slimmer long action, optimized for lighter rifle builds and specific cartridges like the 6.5 RPM and .280 Ackley Improved, allowing for greater cartridge capacity in a more compact action.

How does the 6-lug action contribute to lighter rifle weights?

The 6-lug action is designed to be slimmer than the 9-lug. This reduced profile allows for the construction of lighter rifles, such as the Weatherby Backcountry TI model, which can weigh under five pounds while still handling powerful cartridges and delivering significant energy.

What cartridges are typically chambered in the Weatherby 9-lug Mark 5 action?

The 9-lug Mark 5 action is designed to accommodate the majority of Weatherby's Magnum cartridges. This includes popular calibers such as the .257, 7mm, .300, .340, .3378, .338, .378, and the 6.5-300, all of which require a magnum bolt face.

Can the 6.5 PRC cartridge be used in the Weatherby 6-lug action?

No, the 6.5 PRC cartridge cannot be used in the 6-lug action. The 6.5 PRC utilizes a wider magnum bolt face that is incompatible with the slimmer design of the 6-lug action. It is typically chambered in actions designed for wider bolt faces.
