A well installed brake should not hurt accuracy. It may change the harmonics and move the POI.
If it does some adjustments to your pet load may be necessary. (In most cases a few 10ths of a
grain + or - will do it.
Rarely will you have to abandon the load entirely.
If the brake is not installed properly allowing the bullet to strike the brake (It happens more often than you think)it can wreak havoc on accuracy.
