Well, I’ve been digging through the ammunition I’ve accumulated and I found an interesting find. That’s a few packs of Hornady .17 Mach 2 ammo. Looks like I was looking to purchase a gun with that caliber. It’s not a popular caliber from what I can see. Hornady and CCI are the only ammo makers that stock it. Here’s the particulars on the .17Mach 2:

And as comparison the .22 Win Mag:

The Win Mag in Federal is quite a bit slower, but has considerably better stopping power. So it works well with larger game. Whereas the .17 Mach 2 would probably work best with Prarie Dog sized game. And from what I can remember about the .17 Mach 2, the trajectory is a lot flatter, partly due to the higher velocity.
Savage is the only brand to make guns in that caliber. Here’s one sample website that carries Savage:

Not a bad price. Though, since leaving New Mexico, I haven’t gone Prairie Dog hunting. Don’t even know if there’s prairie dogs in Nevada. And would probably need a scope for these little buggers. I can feel a purchase going on. Maybe pay a visit to that rancher Iknow in New Mexico. Road trip!
Edit: Did some research, and deciding between the A17 and the Mark II FV. If the Mark II had 10 round capability, it would be a shoe-in.
