I have talked to many of the double rifle gunsmiths and those I have talked to tell me this cannot take place and it it did then the rifleing would be very shallow on the inside indeed as the would be pushed out and copper, brass being softer than steel makes this an impossiblity..

Just because a gunsmith is well versed on the needs of double rifle restortion, and repair, doesn't mean he knows everything about physics! I don't really want to get into a big disucssion that nobody can prove, one way or another on the internet, but there are a couple things to think about before makeing up your mind about useing mono-lithic bullets in a double rifle!

Because copper is softer than steel is no guarintee that a copper bullet can't expand a rifle barrel. Mud is softer than steel but barrels are expanded to bursting every day, when sudden pressure is applied! That same mud plug, shouved through the barrel with a cleaning rod, does no damage at all. Like a bullet, the pressure behind the mud suddenly expands it,admittedly to a greater degree than it would a bullet, but does have an effect, none the less!Think of this like a person diveing into water from ten feet,approximently 5 mph, the water simply flows out of the way, and closes behind as the person enters the water. Hitting that water at 100 MPH it becomes a solid, and will crush your skull! Why, because it no longer has time to react, and retract!

The bullet moveing through a rifle barrel will not have the same effect on that barrel if pushed through at slow speed, like with a hydrolic pressure, as it will when shouved through it at 2150 fps. The slower bullet would give the barrel steel, and copper of the bullet, time to react, and retract, the same bullet pushed "SUDDENLY" through the same barrel gives less time for the steel, and copper to react, and retract. This is the same as a bullet pushed against a 3/8" steel plate, slowly, crushing the bullet, and only denting the steel, but the same bullet hitting the plate at 2150 fps, drilling right through, because the bullet doesn't have time to crush, before the steel give way!

That being said, I don't think you will find as many rifleing displacements, as you will seperated ribs, or pressure induced off face condition, from mono-lithics, in doubles.

Regardless, if there is any chance of damageing my rifles from the use of mono-lithic bullets,in my doubles, then they will not be used in my rifles, regardless of evidence shown me, personally! Like my good friend Ray has always said, "where there is smoke, there is usually, at least, a simmering coal of fire"!
