I was checking out a new (to me) gun store today,  one that I hadn't been
in before,  and this guy comes in and picks up a "CZ" rifle -- in
.17 caliber!

Never heard of this one before.  What the guy there told me was that they
take a .22 magnum and neck it down to use a smaller bullet,  giving a
somewhat flatter trajectory?

Any of you guys ever heard of this thing before?  What the heck is it good for?
