This is a bit off topic but I have used 22 caliber, skirted pellets in my 22 hornet, using a magnum primer as the only propellant for clearing rats/gophers out of a barn.
I had to single load them as they wouldn't feed from the rotary magazine on my Ruger 77/R but they were accurate enough at ten yards or so and if they hit anything else, they didn't do any serious damage after passing through. Way less energy than any 22rimfire round, including CB caps but enough at close range to effectively put down a rat or gopher very quickly.
Even cleaned out a bunch of pigeons with this combination.
At the price of primers though, it's not going to happen again.
