Fellas, muzzle brakes do nothing to recoil until after the bullet leaves the barrel. All rifles move back while bullets go down their barrel. The gas escaping behind the bullet pushes the muzzle break forward pulling the barrel with it. As long as that gas doesn't deflect off the brake onto the bullet, good accuracy happens. Note that gas is moving 3 to 4 times as fast as the bullet. It's that ejecting gas that causes most of the felt recoil; only the first 5% of it happens before the bullet's left the muzzle. Muzzle brakes make life comfortable only after the bullet's on its way.
