I have one on a rem700 300wm, came with the rifle. Bought it used.
It really tames the recoil, first rifle I ever had with one and it makes the 300 a puppy dog to shoot. As mentioned by other posters it can throw up debris, part of that depends on how low you have it on bipod.
With the experience from this brake , when I had my 338rum built, gunsmith talked me into a tactical brake(holes only on the sides) helps with recoil and doesn't kick up a bunch of stuff when shooting prone.
