When I was in Zimbabwe the PH handed me the regulations for calibers for each game species. The guide he handed me stated that the smallest caliber to be used on lion, buffalo,etc, was the 9.3 and it must have a muzzle energy of what came to factory specifations for a 9.3x74r, or a 9.3x62. A .338 Winchester exceeds these figures. Long story short: I killed a nice lion with my .338, as I did not have a 9.3 with me. Chronographed 9.3's usually are more than a little off what is written on the box.
I would chose a .338 Winchester everytime. I just happen to favor the .338.
Yeah, I can't see a lion not going down to a .338 Win Mag.
