Duration: 1:43

Brad Kriner from SIG Ammunition discusses the new 277 SIG Fury cartridge at SHOT Show 2020. This cartridge is designed to achieve significantly higher pressures (up to 80,000 psi) compared to standard cartridges, enabling greater power and knockdown energy from smaller platforms. Kriner highlights its three-piece construction, featuring a stainless steel head, brass body, and aluminum washer, which mechanically interlocks to withstand extreme pressures. This design was developed partly due to an Army contract requirement for over 20% weight reduction.

Quick Summary

The 277 SIG Fury cartridge is a new design capable of reaching pressures around 80,000 psi, significantly higher than standard pressures. This allows for greater power and knockdown energy from smaller platforms, with a 140-grain bullet achieving 3,000-3,200 fps and offering 25% more energy than 6.5 Creedmoor at 1,000 yards.

Frequently Asked Questions

What makes the 277 SIG Fury cartridge unique?

The 277 SIG Fury is unique due to its ability to operate at significantly higher pressures, up to 80,000 psi, compared to standard cartridges. This is achieved through a novel three-piece construction that mechanically interlocks and withstands extreme forces, enabling greater power from smaller firearms.

What are the performance benefits of the 277 SIG Fury?

The 277 SIG Fury offers increased power and knockdown energy from smaller platforms. A 140-grain bullet can reach 3,000-3,200 feet per second, and it delivers about 25% more energy than 6.5 Creedmoor out to 1,000 yards.

How is the 277 SIG Fury constructed to handle high pressures?

It features a three-piece design comprising a brass body, a stainless steel head, and an aluminum washer. This construction allows the components to mechanically interlock and tighten under ignition pressure, preventing the head from becoming a weak point and enabling higher operating pressures.

What bullet weights are available for the 277 SIG Fury?

SIG Ammunition offers the 277 SIG Fury in two primary bullet weights: a 135-grain OTM match bullet for precision shooting and a 140-grain tipped hunter bullet designed for terminal performance.
