I have a Webley Mk VI that has been the subject of a recent thread, and I have noticed something about the gun that perhaps one of you can answer. Why is the bore .455 and the cylinder .450? As soon as the bullet leaves the case mouth, it is squeezed down to .450 by the cylinder before jumping into a bore that is .455! I have measured all six throats and they all measure .450. A friends gun is the same way.
It shoots accurately with my reduced load (I know, now, that you should NEVER shoot factory 45 autos) but the bullets are shaving lead as they pass through the narrow throat, and the residue builds up rapidly enough to make loading difficult after a few cylinders full of shooting.
Here is my question. Would it be a good idea to open up the cylinder throats, say, two or three thousands? I shoot commercially cast .452 dia. 255 gr lead. I suppose I should just leave it alone because it IS accurate, but that shaved lead is really messy.....
