I would like to see the damage. I would think, as long as the damage does not cause contact with the bullet, it shouldn't have much effect.
Al, have you tested this or can you reference reliable tests? I don't really want to put a brake on one of my barrels to test this but I suppose I can, if necessary. GD
In both cases that I have first hand experience with, the damaged brake 'crown' showed significant accuracy losses. They were tested A-B-A to verify the results. Both were caliber specific...not 'universal' brakes.
The first one was a 257 WBy with a KDF brake and the second was a 300WSM with a Vais brake. In both cases, fixing the damaged brakes corrected the accuracy issues.
I don't doubt that depending on the individual brake, you may or may not see accuracy issues with a damaged brake 'crown'.
Fortunately, it's easy to test.
Good shootin' -Al
