[QUOTE="Timber338, post: 1033881, member: 33822"] I have been told the sweet spot for brake bore diameter is about .020 over the diameter of the bullet. Any tighter and accuracy can suffer and larger than .030 and brake efficiency starts to suffer. I have also been told by more than one very experienced gunsmith that non-symmetric brakes, such as ones with holes on top and not on the bottom, can cause bullet yaw due to the unequal gas pressure around the bullet as it travels through the brake. and really not trying to start an argument... Anybody with a brake that is efficient and accurate at long range has a great brake regardless of how it was built. Just passing along some knowledge I have learned over the years. [/QUOTE]
