Has anyone heard of the mag na porting process? And if so what did you like/dislike about it? I have a Remington 7mm mag that I'm thinking about having this done to it to reduce recoil but I don't know if it's worth it and if will devalue my rifle. I've heard that a muzzle brake can affect accuracy and don't want that. On there website magnaport.com they say that there is no accuracy or velocity affect from this process. Any info would be greatly appreciated.
