By the way Buffalo Arms sells 9.3X64 brass made from .458 win mag brass with the belt turned off and the rim beveled properly. I have used it in my Home brew 9.3X64 and it's just as good as the Horneber stuff. I have a decent supply of both. FWIW my 9.3X64 with the 250 gr Nosler BT hits 2850 fps easily with sub MOA accuracy. It was built on a FN Mauser action and a Pac-Nor barrel. I remain very impressed with this cartridge.-Rob
