This is a photo of my .505 SRE (in the middle), a cartridge I designed in the late '60's, had built and took to Africa in 1971, where it accounted for, all told, over a period of three safaris, one black rhino, three elephants, and five Cape buffalo.

The cartridge case was formed from .460 WEatherby brass, shortened to 2.500", so as to fit a standard .30-'06 length magazine. Using a 570 grain .510" Kynoch bullet (in the foreground) swaged down to .505", 90 grains of IMR 4064 produced 2150 fps in my 22" barreled P 14 Enfield (visible in the background of the picture).

On the left is my .450 C&W, a rimmed version of the .450 Watts, formed from .375 H&H (flanged) Magnum brass, for use in single shot and double rifles, and on the right my .577 VSRE, formed by shortening .577 NE brass to 2.5", forming a shoulder to headspace on, and turning a rebated rim in the base.

John Buhmiller and I arrived at the same idea at virtually the same time, and in fact, the barrel on my rifle is a Buhmiller barrel. There was also a .500 version of the cartridge, but I never took it to Africa. The reamer was made by Keith Francis and the forming and loading dies by RCBS.

Here are three of the five Cape buffalo, taken in the Selous, Tanzania, 1972:
