Thanks for that Sir Khulu.
50 yards being a long shot on ele is why the call it dangerous game, eh ?

I guess your PH might have been using Federal Premium factory loads if he was shooting the 500-gr HYDRO from a .458 WinMag.

I think you had a much better load in your .458 WinMag, your handload.
Did you leave some for the PH ?
I am guessing Woodleigh made the 500-gr/.458 HYDRO on an exclusive contract with Federal factory ammo maker.
