A good centrefire suppressor should incorporate an internal muzzle brake. Both muzzle brakes and suppressors have the potential to improve accuracy, and over-barrel suppressors with a rear barrel bush have the most potential, especially with lighter barrelled rifles. The reason (as previous mentioned) is the dampening of barrel harmonics by the increased muzzle weight, and the rear bush provides extra dampening effect. Barrel 'whip' is the accuracy killer in most hunting rifles. This can be improved by a good bedding job, then further enhanced by a good suppressor. Whilst muzzle brakes reduce recoil, they can also increase the potential to flinch because of the increased muzzle blast. A good suppressor, correctly fitted, cures both problems.
