I have the 'At-One' CZ457 Varmint, 24".
Shoots very well. I'm using it for 25 yard benchrest (yeah, I can't afford an Anschutz).
Trigger works fine but I wanted lighter than the stock trigger can give, so a Timney is on the way.
We shoot a 10 'roundel' target card. One shot at each roundel. Maximum score is 101. That's 10 points for a hit in the centre dot, then an extra .1 for every shot that's plumb in the middle (=101 for 10 dead centre shots). Centre 'dot' is 4mm diameter, so the .22 bullet is a tad larger. The roundel is 28mm outside diameter (1.10").
This CZ will happily bang out a 100+ score every time.
Last 3 shoots were 100.4, 100.5, and 100.6.
So I am getting better, but it does show the ability of the CZ457 to place a bullet where you want it.
No bedding work done. Nothing altered except I made up another cheek riser from wood as I found that Boyds plastic riser too harsh and 'pointy' on my soft cheek!
Have just changed scope from a Leupold 45x45 Competition to a 'Big Nikko' (Nikko 10-50x60) so now need to make a wee alteration to that new cheek riser as the new scope sits a tad higher.
Faults? Yes, but minor...and I have read of this on another forum. My rifle had loose action screws when it arrived.
Not wobbly loose, but just not snugged up tight. Slightly firm maybe?
I then found that the front action screw was about 2 threads too long and was bottoming out in the action. That front screw is the shorter of the 2 by the way.
Don't mix them up or you really will have a screw bottoming out (a lot!).
Took all of 2 minutes work with a flat file to sort that.
Now I can happily run the 2 screws in with my torque screwdriver and no bottoming out problems.
My CZ likes RK match (red box), and RWS so far.
I did shoot some Geco (rebranded RWS lower drawer stuff) just for fun. Put 8 shots into a one holer just slightly larger than the .22 bullet diameter. (mind you, it's at 25 yards distance. Your distance and YMMV sort of thing).
I am certainly not disappointed with the CZ. Great wee rifle, well made, and extremely accurate.
Can't wait to see how it goes with the new scope and Timney trigger.
