But that’s probably why that ammo is so legendary. But, we can still learn stuff from recoil numbers. I did test other rifles chambered in 6.5 Creedmoor and 308, and while the % of recoil reduction for the muzzle brakes were very similar within the same cartridge … the recoil signatures seemed to vary based on the stock. It’s based on a recent survey I conducted of the top 125 shooters in the Precision Rifle Series (PRS) and top 50 shooters in the National Rifle League (NRL), which are points-race leagues based on the biggest long-range, field-based rifle matches across the country.

The TS Terminator muzzle brake is KG Gunkoted Black & opened out as standard to take a maximum calibre size of .308.

Let me know. The percentage shown is the average of the reduction in overall momentum and the reduction in peak force. The percentage shown is the average of the reduction in overall momentum and the reduction in peak force. Nothing on any sled test can beat it. The variable will be the shooters tolerance to recoil vs concussion/gas. Best For 308: Aero Precision - Lambda Prs65 Precision Muzzle Brake 6.5. Secondly, there is a difference. any help would be appreciated. Standard hole size 6mm, must be opened up to correct calibre by a Gunsmith.
