[QUOTE="Darryl Cassel, post: 26751, member: 34"] Brent That would be the best way to test this theory. Shoot it with the brake and then shoot it without. THE SAME RIFLE. I have done this and there was NO difference in velocity. As mentioned, the bullet is not touching any steel as it passes through the break. Most brakes need .016" to .022" clearance around the bullet to work well. Even though the brake may be 2 or 3" longer it is NOT the barrel with rifling in it. We know that every barrel is different and as the cutter bores the barrel at the factory it wears and there is a slight difference in land depth as this happens. If someone gets a barrel when the cutter is about to be changed, the rifling will not be cut quite as deep as a new cutter will allow. This is extreme but just a .0001" or .0002" could make a heck of a differance if it happened. Just a thought. My experiance is, there is no increase in velocity with a break on.
