I have a number of CZ rimfires.
The CZ 513 "Farmer" was the low end CZ .22 LR. The trigger is heavy and the adjustment options are very limited. However, it has a CZ 452 receiver and a quality barrel. Mine is just as accurate as any other of my CZ rimfires, once you develop the skill to manage the trigger. It's a single hole 5 shot rifle at 50 yards and 1 MOA at 100 yards with
As an aside *Hear me very clearly on this*
You'll encounter shooters who seem to think and promote the idea that unless you have a sub 2 pound trigger or something measured in 20 or less ounces, you can't shoot accurately. That's total BS. Shooters shot service rifle competition for decades with 4 1/2 pound triggers. A lighter trigger makes it *easier* to not disturb the rifle while the shot is released, but it's also a *crutch* for people with deficient skills.
I have a CZ 453 American, and it's consistently a 1 MOA at 100 yards rifle. The difference between the CZ 452 and the CZ 453 is the single set trigger and additional action screw on the CZ 453.
My CZ 453 American is in between my Winchester Model 52"R" sporter and a 10/22.
I also have a CZ 453 Varmint. You'd think the heavy barrel would equate to more accuracy but that's not really the case. I've shot more smaller groups (1/2 MOA 5 shot groups at 100 yards) with the Varmint than the American, but the Varmint has also produced more 1 1/2 MOA groups at 100 yards. It has the same 1 MOA average, but it's less consistent.
I also have a CZ 455 Heavy Varmint. There was a lot of concern that the swap barrel system in the CZ 455 would adversely impact accuracy but that didn't prove to be the case. This CZ 455 heavy varmint is easily just as accurate and consistent as my CZ 453 American.
I don't have a CZ 457, in large part because I just don't like the looks of the rifle. I don't like the lines of the stock or the receiver. But that's just me. I suspect they shoot just fine.
