I'm curious about this myself...I hunt with a .300 Winchester, killed white tails, mule deer, and an elk with it...but bought a .338 for elk/moose. The .338 I bought didn't give me the accuracy I wanted, so I just continued using the .300, but I still have an itch for a .338, even though from what I've read, you really can't tell the difference between the 2 on game.
So- can anyone here tell the difference on elk/moose/bear with the .300 vs .338? Is penetration similar using the "standard" 180-grain .300 against the 250-grain .338 Winchester? I would say the .338 with 250's should give more penetration given from what I've read, but I've never tested them out myself, but that's worth exactly what I paid for the advice...nothing!
