.500 Nitro Express (3 Inch) – We want to put a fresh twist on this very powerful traditional big bore cartridge. We are going to offer this wonderful cartridge in an array of fantastic “modern” bullets and powders, giving this old work horse a little more performance. The biggest limiting factor of this cartridge is the “regulation” requirements for double rifles. Our new ballistic combinations will deliver more performance without excessive pressure and or your doubles regulations. Each one of our offerings is not only performance optimized for velocity. They are also ballistically optimized for the “bullets” terminal design parameters.
