Because I’ve never been able to get the barn swallows to nest under the eaves of the house.
Seriously,
There are a bunch of reasons to shoot at insects.
Around my pond, they are plentiful. They are legal.
The 9 mm Flobert is such a short range shotgun, that it was very easy to sit out by the pond, and take a crack at the bugs.
Nothing to clean up. The fish take care of that.
Don’t have to worry about a season. Don’t have to worry about shot fall out.
Don’t have to worry about noise. Flobert’s are very quiet, and quite slow.
And the ammunition is inexpensive. About 12-15.00/50.
“Move, mount, and shoot”
It is definitely a great way to work on your wingshooting.
June bugs are good as well. But, are slower, and relatively brief in their availability.
