This civilian version of the military cartridge (7.62 NATO) has become the go-to “police/sniper” round, the first cataloged in any new target, precision, police/military, or long-range rifle. Heck, it’s even offered in most predator/varmint rigs. Yet it’s nothing but a “.30/06 short.” Same rim, same head, same body diameters, just 1/2 inch shorter. That means the rifle can be a half-inch shorter, maybe 4 ounces lighter, and 0.001 second faster (just a guess) to cycle. Many claim the 308 Win. is also more efficient than the .30/06. If, by that, they mean it uses less powder, they are correct. But that comes at the loss of 100 to 200 fps MV with most bullets. Game won’t notice the difference, but you might when your bullet lands just short due to more drop and drift. The .308 Win. is a fine little cartridge more than adequate for taking most big game, but with 10 grains less powder in its engine room, there’s no way the .308 Win. can outperform the .30/06.
