I just happened to see at (our good friend) Wal Mart the other day a small flare gun that had some shotgun type shells. I don't have much experience with firearms of any kind, but the shells looked to be about the diameter of a 20 gauge, but only about an inch or inch and a half long. I didn't inspect them any closer than that.

For what it's worth.

Which brings to mind the question, how useful or necessary would a flare gun be in the Midwest? Not trying to hijack the thread, but does anyone see need for signalling in that manner in farm country?
