Use to make it rain starlings when duck hunting few decades back in the San Joaquin Delta. Hit the rolling sky wave just right over the tules and you can drop several per shell.
I've thought of that here. Sometimes the get some big flocks around some of the ranch/farm fields here in the winter. Not as large as I've seen in the valley or over behind the mall in Eureka, but some have to have a couple hundred. Wondered what a spreader choke and some of that #9 tungsten would do from under a roost when they come in at night?
