 There was a lot of wondering of why would we do that? We have submillimeters. We have .30 calibers. Why .270? I don't know the answer to the why. I just know that it works. Basically, you take a .30-06 and neck it down to .27 caliber. And, of course, the .270 was made very popular by the writings or through the writings of Jack O'Connor. He was the shooting editor for Outdoor Life magazine for many, many years. And he used a .270 all over the world.
