I realize the Hornet isn't a speedster---that't what I have my Swift and 22-250 for----I got it for those rabbits that are just a bit too far for the 22 LR in my garden and not notifying the neighborhood of when I pop a cap. I had thought about getting a 17HMR but then I wouldn't have an excuse for more reloading "tools"!!! I do appreciate the info on the primers and powder.
