Sorry a pet peeve of mine but you are not asking what caliber we think is best by your poll but rather "What Cartridge".
Ie: listed are 4 .308 caliber cartridges - 3030, 308, 3006 and 300. All use the same diameter bullet therefor making them all the same caliber!
As to your question I have used a number of cartridges but being I hunt more then deer each year the 7mm rem mag is the one that has stuck (for now at least)
. If deer were the biggest quarry my caliber choice would be a .257. (Cartidge 25-06rem or 25-06AI)
