It would definitely be handy for scaring someone. I loaded it just to see what it would do. Never considered using it but it would work for vicious dogs or some such. Never tried it with real big chunks of rock salt. Now a 10 guage with 1/3" chunks...
Now there's an idea for the next goose hunt. By the time one of those high flyers hits the ground, he'll already be preserved...
