the .308 is tactically better i guess you could say due to the trajectory of the actual cartridge when fired... the .308, since it is a lighter bullet, will stay flatter, longer. however it does not have the punch of the aught 6. both are fine rounds, but i like the 30.06 better. and HD was right when he said it is the most versatile round of all big game cartridges. it will NEVER go away. its the most popular big game round in America and has been for many years.
