Trex,

MidayUSA has brass, bullets & dies available for the 476 Westley Richards (limited supply). You can also buy new ammo from the Westley Richards website, which also lists the statistics (muzzle velocity, energy,..) for this caliber. It sounds like a great round & would have no hesitation in picking up a nice double in that caliber, especially at that price. Most likely you will have to reload & figure out which load shoots the best for that rifle. Good luck, let me know if you aren't interested, sounds like a really good deal.
