Interesting theory espoused on the NovX site.
At the heart of NovX ammunition is the exclusive, cutting-edge SST Stainless Steel/NAS3 shell casing. Stainless is stronger than brass, delivers more energy to achieve unmatched velocity and power, and is vastly superior across all levels of performance. Instead of energy lost when brass expands and contracts upon firing, the stainless steel case of NovX ammunition generates energy gains through limited expansion, allowing more energy to be directed at driving the projectile forward at previously unattainable velocities
Now, first, the stainless case must expand enough to seal the chamber, no? Or am I missing something.
Second, could the "previously unattainable velocities" be achieved through much much higher pressures? And how much higher?
I've seen mention of the cases in the gun literature, but I don't recall seeing the pressure levels mentioned.
I wonder, especially with that .223 round in an AR, will upgraded buffers or recoil springs be necessary? Will use void a mfg warranty?
