Hello;
The method unscrew the barrel, is to use the tool you use, in the mouth of the barrel there are probably 4 or 8 splines, in which a portion of a tool is introduced, while conical square with a handle to rotate. This allows rotating the barrel without any risk of damaging it or leave marks. If you do not have the original tool, very easy, com a copper bar, while making a square conical portion and to which a handle is attached. In any case, suffers damage the tool, because it is softer than the barrel.
Deoxidiser part of the barrel, I recommend immersing the entire piece in light oil and applying heat hastaque the east by boiling oil. Allow to cool and repeat the operation several times. The successive expansion and decline caused by heat, causes the oxide crust is broken and the oil to penetrate.
This method is "forced bullet" because after gunpowder and bullet placed in the body of the gun, the barrel is threaded and the bullet is retained, because it is a little bigger than the caliber of the barrel
