CZ rifles are phenomenon in the world of rim fire rifles.
My theory:
In World War 2, German forces occupied Czechoslovakia, and their industry facilities to continue war production for their needs.
They required from Brno factory to produce 22LR rim fire rifle for purpose of military training.
So they did.
After the war, they had drawings and everything, so they made rifle Brno 2, based on that war time model. Basically, that one was made under military standard, requirements and control. (A unique case of rim fire rifle history)
And till now: brno 2, cz452. continued the tradition of that quality. And they look like real rifles!
455 and 457 are special case diverting from design by exchangable barrels, as per complaints I here at gun range, 457 lacks traditional fit and finish from old models (boys complaining on sights and trigger??). But still it has potential and appeal. (I fired few shots from 457, but not enough to have a valid opinion)
Other rim fires in most cases were made for civilian market demand. (pardon my opinion, others are much less serious). But there are exceptions:
Anshutz restarted their production with focus on biathlon and Olympics, and made their image & quality by that standard.
Finns always knew how to make the rifle, and made T1X based on succesful and proven T3 rifle.
And thats about it. Nothing else is really serious in rim fire bolt action rifle world.
Some factories dont even bother to produce rim fire rifle.
Maybe somewhere there is another jewel of rim fire bolt action rifles, but I am not aware of it.
