- weight reduction – 50% lighter than a conventional brass 9mm case
- nickel has a greater lubricity than brass (nickel’s lubricity was the chief reason why Liberty Ammunition selected it as a bullet jacketing material)
- patent pending design is said to prevent “ballooning caused by pistols and automatic weapons with an unsupported breach”
- head portion can be anodized with different colors for branding or color coding purposes (polished nickel and black heads are available currently)
- less expensive than standard brass
- Shell Shock Technologies claims the cases have been tested to 65,000 PSI. As a reference, the SAAMI maximum average pressure (MAP) for 454 Casull is 65k PSI. MAP for the lowly 9mm +P is only 38,500 PSI
- hey claim that in testing, the cases have been reloaded up to 40x each
Cheaper brass and higher pressure abilities sounds awesome. It does require a different die for reloading since the casing is thicker.
