My experience with brakes is that the only effect that they have on accuracy is that you are more comfortable with the rifle, hence the potential for better groups is enhanced. They don't change POI, but I love being able to watch the bullets hit through the scope. I have installed brakes on even diminutive calibers for that reason alone. They are noisy, but that is why we wear hearing protection at the range. If you are not comfortable with wearing muffs or plugs while hunting, simply unscrew the brake and replace it with a thread protector while hunting and you're all set. We are an authorized KDF Brake installation shop, but will install any brake a client desires. I have a 300WM that is Magnaported and a very lightweight 300WM which has a KDF Brake on it. The difference between the two is remarkable. While the Magnaport gives you around 15% reduction in felt recoil, the brake give more like 40-50% reduction. It's like shooting a 243 instead of a 300WM.
