Forgot that .22 Hornet has a thick rim and some trimmers will not do it. My trimmer is a Lyman and it will take the Hornet case. Unless you are going to do a lot of cases at once the Lee trimmer works well. It can beturned by hand or with a drill. I find that hand turning works well on the Hornet and its thin case. You will need a case neck chamfering tool.

Good luck loading for the Hornet. BTW: i use 45 grain bullets exclusively in the .22 Hornet and it works out well that way.
