The Hornet, in some places, used to be known as the poachers gun. It is quiet and still effective inside of a sane distance, easily attainable with a spotlight or out of season when the game wasn't spooked.
Or if you are able to bowhunt successfully and have legit intentions, the same range is appropriate. Talking to old timers I was told that during the "Dirty Thirties" 30WCF or 30-30 ammo was alot more than Hornet ammo and the Hornet was often found in the hands of cash strapped families with alot more time than money. If it was a choice between feeding your family and obeying game laws, the choice was clear. The game wardens understood that at that time and would only press the issue if there were abuses.
It wasn't only deer that fell to the diminutive little .22 Hornet, the odd moose that was foolish enough to let someone stalk up on him became much needed groceries too.
Much more recently, in 1986, I was 6 and the local sawmill closed putting 60% of the local people out of work. There were some lean years and tho we could afford deer tags, we sure didn't waste them and that was all we had for meat for a few winters in my home anyway. Unlike the oldtimers, we somehow always managed to get our deer within the perscribed season and time.
There was a few 22 Hornets that somehow came up for sale in the early 90's and I suspect they had been out of retirement for awhile about then. I seem to recall they went for dirt cheap when the economy bloomed again. One in particular catches my memory, a Savage 340 in .22 Hornet with a bolt handle that somebody had ground off for some odd reason. I was about 12 and one of my dad's friends had bought it for $75 with 2 boxs of shells.
Hopefully, your little CZ never has to see that duty, it would be a SHTF scene if it did I think. I wish you the best hunting with it. It will anchor deer if used reasonably, but only if used at very moderate ranges. Like I said Bow range is about right. I have tracked a few deer hit with a 22-250 because guys thought they were adequate for 3-400 yds and they merely damaged the deer and I found wolf kills after many miles of tracking.
