There was a thread on another forum about a bunch of guys in So Afrika, who get together every year for a historic hunt. The guys dress and camp period and hunt period. Between that and an early scene from the movie Zulu where Michael Cain is hunting a leopard with his Martini, Ive been hooked.

I believe the ORIGINAL loading of 577-450 was with an all lead 500 gr bullet. The lighter bullets (480 etc) came with jacketed bullets.
