I was curious if you sight in and practice on the range with your brake on and say when you go hunting you take it off. Would it change your point of impact? I know the bullet never touches the brake but still does it change anything?
It could change the POI and likely would, due to the loss of weight on the end of the barrel. You could have a thread protector made the same weight as the muzzle brake and then with that screwed on the end of the barrel the rifle might hit to same POI.
You'd have to shoot the rifle with the brake, and without the brake, to get your answer and be certain about it.
