Bad idea. The 17 Hornady Magnum is a rimfire round. If you dry fire it, the firing pin will fall where the rim of the cartridge would be. If there is no cartridge, the firing pin will slam into the edge of the chamber. Eventually, you will peen a dent into the edge of the chamber. Do this enough, there will be no metal underneath where the firing pin lands, making for unreliable ignition when a cartridge is present. Put a spent case in the chamber to protect the chamber before you dry fire it, if you must do this.
