This cartridge was invented by forum member xausa in about 1973. The name stands for Very Short Range Express. It is basically a Nyati Short, based on the Nyati case with a brass length of 2.5" so it can be used in a stand length action.

This post tells about the cartridge and a project I did with one of my two rifles in this caliber.
