Yes, run a .270 for deer sized game and a .338 for anything bigger than deer sized game stopping at when you use a .458 for heavy dangerous game
Just to be a contrarian, what's the difference to the hunter between "heavy dangerous game" and just "dangerous game" if one is an elaphant and the other a brown bear or lion? For example: On safari, would a hunter be compelled to change weapons if both ele and lion were on his agenda? He might choose to carry two rifles, but does he need to? In Alaska, a solo resident hunter may have several licenses in brown bear country: Would a majority be toting a .270 or something bigger... how much "bigger" to make a difference?

www.bigbore.ca Heavy dangerous game in Africa are elephant, rhino, buffalo, hippo. In other places you would probably include any of the bovine species if they were huntable such as gaur, banteng, other buffalo, feral bulls etc. Dangerous game would include (if they were huntable) tiger, jaguar, lion leopard, crocodile, brown/grizzly/polar bears, not sure about gator, not sure about cougar. Now if I could hunt gaur in the jungles of Cambodia, that would be the ultimate for me.
