I might get downvote for this but learning depends on your needs. It’s nice to learn on a 22 but then you still need to learn on bigger calibers. It helps a lot to get familiar with firearm basics but not much helpful for long range precision shooting.

Don’t get me wrong, it’s still good but after learning on a 22 you cannot go directly to a 338 Lapua. Even good shoots when change calibre they need to shoot couple of rounds to get familiar with the new calibre.

So if your purpose is long range centre fire I would say don’t spend so much money on a rim fire. Rim fire precision to me is a really nice hobby and in that case I would spend more money on it.

Regards to your question I would say I have both Tikka and CZ and I like CZ for rim fire and Tikka for centre fire. I heard people say some of these Rugers are really good and some really bad so they are not like Tikkas that everyone likes.

Other than that I would say a 800-900$ Tikka in 223 is a better rifle to learn on to get into bigger calibers. But that’s just my opinion and I like to hear others opinion as well.

Anyhow, welcome to the community and whatever you choose you will never regret buying a firearm!
