Reloading .303 British : Federal. 308 Ammunition

This is published data that I located with help from actual Federal Cartridge Company employees . The only reason I did all of this research was to assist the folk out there that have a fear with firing  .308 Winchester in a rifle with a 7.62x51mm designation. The main fear being that 308 pressures far exceed that of the 7.62. My finalized research found that the commercial .308 ammunition produced by Federal pictured above, is in fact, the same identical ammunition supplied to the US Military. Specifically for use in sniping. If this to you has gotten out of hand, then I apologize to you and you only.
