What IS an airgun?

by B.B. Pelletier

Simple enough question, no? Maybe you get confused by certain air-powered tools or perhaps a slang reference to a paint sprayer, but most folks know exactly what you mean when you say airgun.

Think so? Think again.

The term airgun isn’t found in most dictionaries, yet. You’ll find your spell-checker wants you to write it as two words, but that’s not what today’s blog is about. I really want to know if you know what’s encompassed by the term airgun.

Some of you have already stopped reading to formulate an official-sounding definition that goes something like this: An airgun is any smoothbore or rifled gun that propels a projectile by means of compressed air. As you stand back to admire your work, it suddenly dawns on you that your definition doesn’t encompass any of the guns that are powered by CO2. Don’t you hate it when that happens?

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.
