Yes...
I've had my CZ453 for a couple of years now. It seems to dislike cheap ammo, but loves Wolf Match Target ammo.
I had my gunsmith pillar-bed the action screws, glass-bed the receiver and re-float the heavy barrel to get everything I could out of the rifle. I put 21 inch/lbs of pressure on the front action screw and 25 inch/pounds of pressure on the rear screw... and mounted a 4-12x40mm AO mid-priced Bushnell "Legend" scope with "plex" crosshairs on it which gives a very clear, sharp "picture" and gathers 91% of the available light.
Set on 12x, this combination plus Wolf Match Target ammo puts bullet after bullet through almost the same hole at 50 yards off the benchrest using a rifle rest with sandbags under the forearm and at the toe of the butt-stock.
A small screw inside the trigger guard adjusts the set-trigger. If you turn the screw "in", the trigger gets lighter. However, if you turn it "in" too far, the rifle becomes DANGEROUS because opening the bolt or moving the safety off "safe" will cause the rifle to fire... so adjust the set-trigger screw
CAREFULLY!
The 453 "varmint" rifle is a very accurate .22 rimfire rifle with the right ammo. I tested over 30 different brands/styles of .22 rimfire long rifle ammo... CCI Mini-Mags shot the best in "cheap" ammo, but not nearly as accurate as Wolf Match Target long rifle ammo.
Hope this post helps you...
Strength & Honor...
