Centerfire and rimfire refer to where priming is in the cartridge.

In centerfire, there's a primer cup inserted into a pocket in the center of the cartridge. The firing pin dents it, firing the cartridge. One benefit is that after you use the cartridge, you can punch out the primer on your press, put in a new one and reload the cartridge for some cost savings. .223 Remington is a centerfire cartridge that's a varmint hunting standard. If you go to this URL and look at the picture of a .303 cartridge by the header "Centerfire", you'll note a circle in the center of the base. That's a primer: en.wikipedia.org/wiki/Cart...(firearms)

Rimfire cartridges are only made in .22 (short, long, long rifle) and some new .17 caliber rounds I'm not up on right now. In rimfire rounds, there's no replaceable primer: a primer paste is spread around the inside base of the cartridge (the rim). The firing pin of the gun actually crushes a part of the rim, firing it. These rounds can't be replaced. Couldn't find a picture but imagine a flat base with no primer structure visible form the outside.

One safety note: when firing a cartridge in a gun, you should only use a round that the gun is chambered for, it'll be stamped on the gun (usually the barrel), often both the cartridge base and the box the cartridge came in. If they don't all agree (aside from a couple cases like .38 special, shot in a .357 magnum gun) do NOT try to shoot that cartridge in that gun. As an example, you can chamber a 8mm mauser cartridge in a .30-06 rifle but trying to drive a 7.9 mm bullet down a bore 7.62 mm in diameter usually destroyed the gun and occasionally the shooter. I hope this doesn't sound patronizing, it's just that it sounded like (and this could be my reading error) you wanted to shoot both .22 rimfire and .223 or something like it in one gun.

Thanks for the explanation.

I'm not a reloader, and don't expect to become one. Is there anything else I should consider.

And no. Just want to buy the right gun....not use different ammo in the same gun.

Thanks!

It really depends on the use you intend for this gun: for long range varmintnig, you'd want something like a .223, I think. For short range plinking, a .22 LR rimfire.

Laws also become an issue. In California, your choice of .223 can't include an AR15 (about my favorite rifle) or many other semi-autos.

Nice...CZs are supposed to be nice guns.

One thing to keep in mind is that .22LR is only effectively accurate out to about 100 yards and a windy day can blow that. A .223 in a similar ifle might go out as far as 600 yards.

The flip side is that .223 is really inexpensive ammo and you can afford to shoot with it a lot...

Ok, dumb question, but what would I need 600 yards for? Or is it that if it's accurate to 600 it will be more accurate at the 50 to 100 yards....

I thought the deal was .22 ammo was cheaper ??

The cool thing is that most gun owners won't tell you what you "need", that parts up to you ; ) However, some people choose it because it's a different kind of shooting and accuracy. At 600 yards you learn (I am told by people like Ghengis...) to read the wind, consider trajectory and involve other factors that are irelevent to someone who shoots at 50 yards.
That would be on reason to choose the more expensive, and faster .223 over far slower and less expensive .22 (he think he typo'd...)
