I would think once someone gets their hands on some 17 hornet brass it will cost pennies to load vs the expensive and almost impossible find rimfire ammo. Imo you can load and shoot any time vs letting gun sit untill almost impossible by ammo to find shows up. I quit buying new odd ball calibers years ago that only gain a couple hundred FPs. Imo the same velocities can be obtained with calibers that have been around for decades, or more, and hand loads. It's still the same 17 cal bullet no matter what case it sits in. Had a 17 rem, fireball, hornet, and HMR years ago. Got rid of all of them. I prefer a 22 wmr, .223, and .224 over it.
