Roundball accuracy in smoothbores

by B.B. Pelletier

I’m now back home. My surgery was successful, and I’m on the mend and on the road to complete health. While I’m tired, I feel better and have more energy than when I was in the hospital. I’ll be able to address some blog questions but not all. I’d sure appreciate any help our regular blog readers could give in answering some of the questions.

A fair question to ask is why roundballs are not as accurate in smoothbores as they are in rifles. While it may seem counterintuitive to most people that a spherical object could need stability in flight, in fact it does. When you spin a spherical object, you’re promoting stability by averaging the instability in the object. Here’s what I mean by that. When you spin a sphere, you set up an arbitrary north-south pole. And, whether or not the object is fully stabilized by this spin, it’s more stable than if it had no spin at all. That’s because you’re making the heavier and lighter parts of the sphere rotate around the spin axis. read more
