RE: Browning BOSS
On the positive side the boss does let you tune the gun for a specific load which can help accuracy a great deal with some loads.On the negative side all boss equipped rifles have a shorter barrel which results in a loss of velocity.The boss on my rifle also came loose a couple of times which changes the point of impact noticeably.If the boss with the brake is used you must wear hearing protection at all times ,even when hunting because it greatly increases the sound volume to the shooter.I also find that I can achieve just as good or better accuracy with handloading than with the boss.
