So I have long used Lance Shively Trigger shims --They make a Savage Accutrigger worth having. I contacted Lance about CZ 457 shims--he said he was working on prototypes and sent me a package. We have 4 MTR's and have been shooting more and more 22 matches--I like the factory CZ trigger--I tried a Jard but found it just plain mushy--went back to factory trigger with a lite spring--
I checked and the CZ trigger had what seemed like a lot of side play--I used one shim from Lance about a .003 or .004 IIRC and it took almost all of the side play out--so when I went back to fine tune my sear engagement it was a game changer! I think without the side wobble that the sear engagement is maybe more stable? Can't say but....I was able to really fine tune the sear and achieve a trigger feel that I have not been able to get until today.
We have been setting over travel, and spring pressure then really centering on the sear. I cock the rifle and very slowly turn the sear adjustment clockwise until the rifle fires--then back out about 1/4 of a turn--a little testing will show you how sensitive this is--you have to back out enough so it cocks each time but will not "bump fire'
1/2 turn out seems way too much so just test for yourself and get the 'feel" that you like.
Lance ships fast and these shims are a CHEAP way to improve the CZ trigger.
We have found that when adjusting the CZ trigger--it will have a "ping" when it is just right--if it sounds soft or "dead" just keep fine tuning until you get the feel you want with that distinctive "Ping!"
This is all just our experience so far--I don't claim to know a darn thing but have been working Hard to get our CZ's as competitive as possible by just being observant and testing things ourselves.
