Trying to get info about the best all around big game cartridge is far to complicated so I have opted to reduce the available argument down to the best all around caliber!
My guess is that the 7 will get the most votes however the big 30 might have a chance to dethrone the 7.
Or has the mighty 6.5 dethrowned them ALL? I think not
When results are in and the campfire has chosen a caliber, let's start a new thread to determine the campfires opinion of which cartridge would best suit the caliber.

Big game?? Talking USA? Africa? World?
From your comments I'd suspect you might be talking the lower 48, if so, I'd pick the 300 Weatherby with 200 grain partitions. I'd probably pick that combination for Alaska too; I wouldn't use a 7mm or 6.5mm on big bears, maybe others would. If you leave off big bears, then in my opinion, the 7mm RM would do OK, but not my first pick for bison.
I think many people would pick a 375 H&H or 375 Ruger for Africa. I would prefer a 375 H&H, though I picked a 375 H&H AI, which can shoot 375 H&H cartridges or 375 Weatherby cartridges just fine and if wanted can exceed the 375 H&H in velocity/power or equal the 375 H&H at a lower pressure.
But I wonder if the 375 would be the pick for elephant hunters, I think not, maybe start at the 458 Win and go up from there. Take those comments about Africa from a guy that has only been to Africa once and the biggest game I saw was a hippo.
