SIG Sauer Introduce .277 SIG Fury Cartridge

    SIG Sauer introduces 277 Fury (SIG Sauer)

    SIG Sauer have released their 2020 catalog and there’s lots of new products to get excited about but one thing that jumped out at me was the introduction of a new cartridge – 277 SIG Fury. Developed by SIG Sauer the new round is the result of their work on the US Army’s 6.8mm Next Generation Squad Weapons (NGSW) program.

    I got my first look at SIG’s new hybrid case ammunition last September at DSEI 2019 – be sure to check out my full write up on SIG’s NGSW prototypes and their ammunition. At DSEI Ron Cohen, SIG Sauer’s CEO, took the time to explain the new ammunition to me, he felt that the hybrid approach with a steel base and brass case offered the most practical way forward.

    277 Fury is unlikely to be identical to the 6.8x51mm SIG are developing for the US Army but it does share the same origins and future calibres using the hybrid case tech are planned with 6.5 Creedmoor and 7.62x51mm displayed at DSEI.

    SIG Sauer describe the 277 Fury as ‘revolutionary’ and the ‘next generation of ammunition’. The catalogue touts decreased bullet drop and increased energy on target.

    The catalog shows a pair of two graphs highlighting the SIG Fury’s better performance verses 6.5 Creedmoor stating 6-9 feet less drop at 1000 yards and up to 25% more energy on target at 1000 yards.

    The catalog shows the new round in both Elite Match Grade and Elite Hunter Tipped forms with 135 and 140gr projectiles respectively.

    Currently the only rifle to chamber the new round is SIG Sauer’s new CROSS precision hunting bolt action. Below is the CROSS rifle’s page from the new catalog:
