Cool. I met Elmer while autographing his books in Dallas. Glad to have done so.

I found a great leopard load to be the Nosler 300 grain .458 Protected Point at 2200 fps. It would likely work well at less than 2000 fps, but we loaded them up to the max as recommended by Nosler.
Winchester Loaded their Supreme .458 PP to about 1850 and it was a supreme deer load.
