they make a 452 Scout that has a short barrel and a youth length stock,and a 513 Farmer that is full size but has a non adjust trigger,,both these models are some cheaper and they sold for less than 300 new,
on all other models 300 is a very good price if condition is anywhere near decent.
if it is a 452 or 453 of any kind other than the Scout it is a very very good price,,as they are discontinued and are getting scarce.
did the rifle have sights and how long was the barrel,,I could determine the exact model with that info..
I am at 7 CZ rimfire rifles and they all average out about the same accuracy wise,,with the individual rifles preferred ammo it is pretty easy to shoot 1/2 inch 5 shot groups at 50 yards,and I have seen several that would be 1/4 inch,
lately I have been shooting my 455 Varmint with the Bushnell Elite 3200 straight 10X scope and a 30 MOA taper scope mount,zeroed at 100 yards I can dial in adjustments and hit the steel plates at 300 at least 7 of 10 shots,I run out of adjustments at 380 and have to hold on the first mildot with the scope maxed out at the 400 yard gong,but it is 24"x 24",,
if you buy it and dont like the trigger I can tune it to be the best trigger you own for about 10$$
