Interesting article, almost had it right - up until they referred to the "bullet" being about the size of a AAA battery.
The bullet might not be but the cartridge is, and to Joe Public they are the same.
There are other glaring issues in the article besides that:
"The faster a bullet hits the tissue, the more it's going to fragment," says Fackler. "Bullets that go faster cause more damage. It's that simple."
I thought that had more to do with bullet construction than speed, sure a faster bullet that breaks apart will send the peices farther into the tissue but it isn't the speed that causes the initial break up but impact force (more mass would cause the same thing at the same speed).
"Larger rounds are not necessarily better, they also said. Other factors such as the weather, the amount of light and the bullet's angle of entry also figure into how lethal a single shot may be."
Ok, these all affect SHOT PLACEMENT not the effectiveness of the ammunition. It was a government study.
"The M14 rifle used by Joe Higgins was once destined to be the weapon of choice for all U.S. military personnel."
Sure was issued to a LOT of people for one that was DESTINED to be. Hell we still had a dozen of them at Security when I left in 2003 that no one was qualified on except Range Staff Most built before any of us were born, I saw a July 63 stamp on a couple.
