On the ammo and two piece cases.
From the Seismic website:
"What is the average velocity of your 9mm 185gr?
The velocity typically ranges between 900-1,000 FPS depending on barrel length. We recommend using a full-size pistol or carbine for optimum expansion and performance."
"Why do you use NATO instead of SAMMI specifications on your 9mm 185gr?
We chose to use NATO because of the ShellShock™ cases which are stainless steel. SAMMI spec for 9mm calls for a conformal transducer to be used on the case itself and is designed for brass cases. NATO measures the pressure at the case mouth and doesn’t factor the case material in its measurement."
"Is your 9mm 185gr +P or +P+ rated?
Since we use the NATO spec there is no +P or +P+ standard."

A good look at their website shows an interesting lack of precise information.
They use Russian made ShellShock aluminum/steel cases. These are two piece cases that have an aluminum base and a nickel alloy stainless steel upper. these have a step inside the case that helped to increase pressure in some manner. Look at their website for a bit.

A good many promises of extreme performance. Big claims need big proof to back them.
