.308 can be used effectively out to 1 mile on man sized targets...... that is with an accurate gun, proper training and quality mil-dot based optics.
Try still hunting with a rig like that
I am not a target shooter but a hunter, I have hunted with a 308 win for about 30 years.
I've shot moose, elk, deer and black bear with it my closest shot being under ten yards and the farthest being measured out at over 550 yards (moose)
