[QUOTE="Vern396, post: 3075704, member: 126746"] It’s not scientific, but I did see a YouTube video that showed empirical proof of the concept. A guy was comparing the 270 Winchester to the 30-06 using hunting ammunition by the same manufacturer. Though loaded with the same weight bullets, to nearly identical velocities, the 270 would punch through a steel plate, but 30-06 would not. When looking at the sectional density, the sectional density of a 270 bullet exceeds that of a 30 caliber bullet of the same weight. An Army engineer studied the effects of sectional density in artillery long ago. Perhaps sectional density played a role in the Army’s selection of the 270 Furry cartridge. The Furry is purportedly to be loaded with a 135 gr otm at a velocity in the neighborhood of 3000 fps. Essentially, it has the ballistics of a 270 Winchester in a short action cartridge. [/QUOTE]
