For a few years, several of us used the 308 for 1,000 yd BR, and several of us used it on the 100/200yd BR line with very good success. Not to mention for decades, it was the go to caliber for National Match and of course, Palma. It was easy to create a very accurate load and with a little more time, super precise BR loads that shot bug holes.
As a hunting caliber, it can be loaded to the ballistic equivalent of most 30-06 factory loads.
With the advent of high BC bullets in smaller calibers and the modern magnum mania, the 308 has faded from the spotlight, but in the right hands with correct loads, she still remains a very capable cartridge. I still own a few, and one 26" heavy varmint/target rifle that with 155's and 168/175 hand loads shoots very small groups at 600 and 1,000yds. It is still a great cartridge to train people in the sport of LR shooting.
