jgguinness Posted June 23, 2012 Report Share Posted June 23, 2012 I too have fitted a Yo Dave kit and have 3 springs left along with a couple of shims if anyone wants them. What a good bit of kit though, very swift delivery from Canada and works a treat. Jonathan Quote Link to comment Share on other sites More sharing options...

I got a CZ452 .17hmr earlier this week, with what appears to be a trigger made for desperate Dan :lol: I zeroed it in last night at 100yds and as I am looking at the target I can see the cross hairs start to move as I sqeeze on the trigger and it is making the groups spread out to just over 1 inch, I can hold the cross hairs spot on with my finger on the trigger but the more I squeeze it all starts to wander off. Do you think these bits may help to lighten things up enough to stop this? Cheers Schmoo. Quote Link to comment Share on other sites More sharing options...

Catweazle Posted June 30, 2012 Report Share Posted June 30, 2012 I'm going to go against the grain a little bit here, and question how sensible it is to fit a kit that works by stopping the trigger from fully engaging, on a hunting rifle. I'm not suggesting that hunters should settle for less accuracy, but their rifles get rougher treatment and sometimes the trigger is touched before the quarry moves, meaning a shift of position and try again. I agree that the standard CZ springs are way too strong, but they can be shortened and adjusted quite easily. My CZ triggers had the factory-standard feel, like pulling an anvil across a concrete driveway, but a bit of polishing improved matters without compromising engagement.

Catweazle, Can I just simply replace the spring for a less strong one ( if thats the correct term for a spring strength ) There appears to be no creep, I have to pull the trigger a good few mil before it fires but there is no slack, as such, I am feeling resistance all the time the trigger is being pulled. Can I simply adjust something on it for now and see how that feels in the field ? ATB Schmoo. Quote Link to comment Share on other sites More sharing options...

This will reduce the trigger weight, but it won't reduce the creep ( which is the trigger movement before the trigger breaks ). The standard creep on mine was quite "gritty", so I carefully polished the sliding surfaces. Personally, I don't mind the creep as long as it's not too gritty or heavy. I like the idea that the trigger is well engaged. If it was a target rifle it would be modified quickly. Others will disagree. If you're not confident with metalwork / handwork then don't mess with the trigger faces, you can easily mess up the angles and make a dangerous trigger.

rapid rich Posted June 30, 2012 Report Share Posted June 30, 2012 (edited) DONT set it too light DONT over shim it TEST, TEST and test again (bump test/rubber mallet on butt pad) Rich Edited June 30, 2012 by rapid rich Quote Link to comment Share on other sites More sharing options...
Verminator 66 Posted June 30, 2012 Report Share Posted June 30, 2012 DONT set it too light DONT over shim it TEST, TEST and test again (bump test/rubber mallet on butt pad) Rich yes totaly with you with what you say I fitted a timany trigger and what a difference that made Quote Link to comment Share on other sites More sharing options...
the enigma Posted June 30, 2012 Report Share Posted June 30, 2012 DONT set it too light DONT over shim it TEST, TEST and test again (bump test/rubber mallet on butt pad) Rich :yes: And not just after you fit it,but on a regular basis. The trigger will wear over a period of time. Quote Link to comment Share on other sites More sharing options...

I cut one loop of of the spring and it has made a world of difference to my groups at 120 yards , I am now getting groups of less than one inch, which for me is fantastic Before people start, I have tested the rifle empty, I have cocked the bolt and thumped the stock with a rubber tent peg mallet and I have whacked the butt of the rifle down on the table and all was safe. I do still need to apply some pressure to the trigger but not as much as I did before I snipped one loop off of the spring. When I get the time I will address the creep which is a few mm before it fires, and for those who are a tad worried, I will replace the spring for one which comes with the trigger kit, while I am doing the creep. I will get the sears polished if need be at a later date, by a gunsmith. Schmoo. Edited July 3, 2012 by Schmoo Quote Link to comment Share on other sites More sharing options...
