The Ultimate Suppressed 338 Caliber Rifle - 338BR / 338 Whisper

This is a subsonic-specific 338, that's built for ultimate long-range shooting with a suppressor. What we ended up with is a 338 BR (7mm BR necked up) built on Defiance Machine Ruckus action with a 16.5" K&P barrel with a 1:6.5 twist. This barreled action sits in a Grayboe Renegade stock with a Timney Calvine Elite trigger, topped with US Optics FDN 17. The whole rifle was built because the Thunderbeast 338BA needed to get more range time and this was the perfect way to make that suppressor shine.
