I recently purchased the 457 Varmint in22lr non MTR. Have only shot it in back of my house at 25yds. Haven't been to the range yet for 50yd shooting. Just from the research online, It seems a lot of folks are not getting very good accuracy. Some say no matter what ammo they have tried. The last CZ I owned was a 452 Varmint in 22LR years back. The 452 was very accurate even with the Federal 510 rounds. I'm just trying to see if a lot of folks on this forum have had poor accuracy out of this particular model. Also, if anyone found solutions to accuracy problems other than barrel replacement. I plan to install a yo dave trigger. Thanks for all input! 
I plan to experiment with action screw torque.
