I never much saw the real purpose of the .17. IMHO it is not as accurate as a .22, a LOT noisier, ammo is more expensive - even today with the .22 shortage going on; the holes the bullets make are not visible at a 100 yard distance, so you need to physically check your target - can't even see the holes through a spotting scope.
If I need something hotter and more powerful than a .22 LR I go to a centerfire cartridge.
One of my shooting bud's has the same CZ 453 American as I do except mine is a .22LR and his is a .17. We jokingly compared them over a week's hunting trip while we were not in the Fields and I am glad I bought the .22LR version. Not withstanding the current .22 ammo shortage, what he pays for 200 rounds I can get a Brick for.
My feeling is that 10 years from now most guys won't even know what a .17 is, while the .22 LR will aways be around. My opinion is that they came out with the .17 more for marketing/sales than the actual need for it. You know, just like Marlin came out with the .444 Marlin - not saying it isn't a viable cartridge, but what was wrong with the 45-70?
Well, just my opinion of course........
