Research notes
The 408 Cheyenne Tactical, is a counter sniper rifle cartridge, that was developed by Dr. John D. Taylor and William Wordman and was designed specifically for the military market in the hope that it would be both a cost effective and ballistically superior round to the existing military long-range cartridges, the 338 Lapua and the .50 BMG. The .408 Chey Tac is based on a wildcat cartridge, the .400 Taylor Magnum, that used the British .505 Gibbs as the parent case but significantly strengthened to handle the pressure.
VRI is a new primed unloaded case for Vigilance Rifles Inc., Chino Valley, AZ with cases made for them by Bertrams Australia.
