I have a brake on a Savage 10ML and it does help with recoil when shooting smokeless, which is what I used most of the time. It still helps with recoil with black powder, but I don't think as much, but then again the gun doesn't recoil nearly as much with black powder either, so it is hard to tell. It also does seem to help with visibility somewhat when using black powder (I am using a scope on it). You may also have some issues when using sabots too. Check out Bad Bull muzzleloaders they have some info on their site about using brakes on front stuffers.
