the 270 was created for long range shooting in the west and north west. But it doesnt have the energy neede to down a deer or elk at sy 500 yards that a 30 cal does. the main diference between 308 and 30 06 is the 30 06 at 600 yards picks up speed and the 308 doesnt. both bullets will drop anything you would hunt and it is just a matter of funding a bullet that does whta you want. i would suggest that first you find a bullet that your gun likes and shoots good group 1/4 to 1/2 inch suggested. then you need to train the shooter . i would start shooting at 100 and then 200 so on and dont feel that you have to be accurate all the way to 1000 yards . a lot of shooters 300 to 400 is tops. a trained shooter like myself can do 1000. if i can give you any other help email me .
remember: match bullet to gun, gun to shooter , train the shooter
