A process of manufacturing bullets out of lead wire using great pressure to cut and 'swage', or 'squeeze' the bullet into shape. Swaged bullets can be jacketed. This is not usually a practical proposition for home manufacture, due to the large forces and relatively expensive equipment involved.

A process in which by hot or cold working the cross-sectional area of metal stock in the form of bar, rod, wire or tube is progressively reduced along its length by forging, hammering or squeezing. Ina rotary swage the reduction is achieved by rapid impact blows from revolving dies.

Enlarging one tube end so end of other tube of same size will fit within.

Offsetting a hinge leaf at the barrel so the surface of the leaf is not tangent to the outer diameter of the barrel.
