L Cooper, I did mention that I have, and shoot, a .458 Win Mag. I don't find that so bad, and I dont see where the .416 would be any worse.
I use the .458 for hogs now and then. Two years back, I took a 300+ boar with it. Belive me when I say that even that caliber is not always a one shot kill on a boar.
I don't think I can resist the Siren's call of this one.
