There's no intrinsic accuracy gain in stabilisers or brakes. All they do is aid the shooter to have better follow through. However if you can follow the shot better and see it in flight you can gain more knowledge of what the wind is doing and if the shot is going where it should. It's always possible to pull up targets but on battered targets if you've not seen it land then you are guessing.
