An interesting article. Discusses the difference between sectional density and its importance to external ballistics and terminal sectional density, and its importance to penetration. Not sure that the term “terminal sectional density” really makes sense to me. It’s about terminal performance. And I think most experienced hunters, whether consciously or subconsciously, do make a calculation about sectional density and terminal performance. It’s been a long time since I’ve bought manufactured ammunition, but I would imagine that in hunting ammo, manufacturers generally do a good job of matching ballistic performance and terminal performance, no?
In any event, the assertion in the opening paragraph that sectional density doesn’t really matter seems gratuitously provocative. On the other hand, it will be music to the ears of the 6.5CM haters
“We need to talk about the sectional density (SD) of an unfired bullet. Why? Because you’ve been led to believe that it matters. And it doesn’t really. Not for most of us. I know this may come as a shock, given that many shooters believe that the higher a bullet’s initial SD, the deeper it will penetrate. Bullet catalogs list unfired SD as an important specification, after all, and the supposed correlation of SD and bullet penetration is all over Internet chat forums and even articles like this one. But if you just think about a bullet made of cheese, you’ll see what I’m getting at.”
