One other thing I have given some thought to is the metallurgy of the brass used these days. Brass can have a wide range of alloy. Things that affect strength of the casings...

Annealing (v) Multi-phased heat and stress treatment that alters the microstructure of a metal adding strength, pliability, and hardness.

Ductile, Ductility (v) A physical quality ascribed to a metal that will permit plastic elongation (wire drawing) without fracturing.

Forging (Forged) (v) Heating a metal to a temperature where the metal becomes malleable (red hot) or deforming its shape by compression or exertion of force (hammering or cold forging).

Malleable, Malleability (v) A physical quality ascribed to a metal that can be compressed, deformed, extruded, hammered, and rolled.

Plastic, Plasticity (v) A physical quality ascribed to a metal that can be bent and worked without rupturing. A non-brittle metal.

These terms were borrowed from http://www.allaboutgemstones.com/glo...etallurgy.html to provide some insite to what metals go thru while being produced or used.
