Of the two listed brakes, which in your opinion would have better performance and why. To be mounted on a .338. I am leaning towards the muscle 4 port magnum, due to the two ports closest to action spray at a 90* angle to barrel , while the FB are all ported on a unknown angle rearward. I have no experience with either, other than what information i gather here and on the internet. Positive or negative comments on both are appreciated.
