CZ 457 YoDave Trigger Spring and Trigger Adjustments

[@fairviewprecision]

Good stuff man! I’m surprised that I see this. I’ve been in “shoot tube jail” for a few months… I’d be surprised if they don’t delete this comment. Keep up the great work!!

Thanks! I hope the hand/wrist is all better.

Thanks for the video. I did the exact same procedure a few weeks ago, but using the YoDave spring. The original spring allowed me a pound of pull weight, and the YoDave spring brought it down to 10oz, safely (lateral movement and hitting the action will not fire). It could go down to 8oz but was unsafe (lateral and hitting will fire). One thing though, is that I installed a YoDave firing pin +10 spring and it made the trigger weight twice as heavy, cancelling the benefits of the new trigger spring, so I reverted to the original firing pin spring. I do not know why your lightest pull weight with the YoDave spring is over a pound, it should be around 10oz maybe less, that's the general consensus on the forums among CZ shooters, as well as my results. Keep up the good work!

[@CopperStarPrecision]

Interesting. I couldn't get either of my stock triggers under 2lbs. The YoDave brought it to 1lb which I'm happy with. With mass produced factory triggers it can sometimes be luck of the draw. Maybe I could get it lower by polishing the internals, but I'm happy with where it is at currently.

​​@@CopperStarPrecision Didn't you put in a PP Metal Cocking Indicator and YoDave +10% Striking Spring? Was this video made with OEM parts? Edit: I watched your bolt upgrade video again. At the end you said the Metal Cocking Indicator doesn't work well for you with the YoDave +10% Striking Spring. I'm guessing because the Metal Cocking Indicator compresses the striking spring slightly.

[@CopperStarPrecision]

@@Toimu13 Correct. I'm just using the metal cocking indicator, but not the +10% spring since the bolt close was too stiff with it installed.

Im John Well done and much needed video . Thanks for showing that to us. Lighting is way better this time around! Keep em coming

[@CopperStarPrecision]

Thanks, will do!

[@victoraviso2798]

Thanks for the info

[@CopperStarPrecision]

Any time!

[@kevinmole8996]

Great video! The most frustrating part of this process is getting the pin back in the trigger without boogering up the hole with the punch.

[@CopperStarPrecision]

Very true

I bought 10 springs from McMaster for the same price as the YoDave single spring. I suspect that is where he buys his springs. Mine is sitting at 6oz.

[@Cristopher1976]

McMaster Carr has a couple of springs that can work. If I ever use a base class rifle I will probably just go yo dave.

[@CopperStarPrecision]

Agreed. YoDave is a simple solution.

[@pevelyhomeowner327]

YoDave’s kit is nice, but as you mentioned there’s other places to get a spring.

[@CopperStarPrecision]

Yeah, YoDave is just a convenient option for something that you know will do the job.

Is this considered a “trigger adjustment” with respect to the NRL22 Base class rules, or does this push this rifle into Open class? And if this is within the realm of adjustments for Base, just have far can you go? For instance, if I had a 10/22 with a stock trigger, could I rebuild that trigger assembly using BX trigger parts, but not actually replace the assembly itself? I personally find it ridiculous that I can’t replace one type of a Ruger 10/22 factory trigger with another type of a Ruger 10/22 factory trigger, especially since Ruger sells multiple versions of their 10/22 with the BX trigger.

[@CopperStarPrecision]

It's kind of a grey area. My interpretation is that this is legal adjustment (spring weight) to the factory trigger. The rule states that "Safe adjustments to the factory trigger are allowed but aftermarket triggers are prohibited". This isn't an aftermarket trigger and the trigger is still safe. However, the spring isn't a factory part, so I could see the argument going the other way as well. I agree that for Ruger you should be allowed to use their BX trigger since it is a factory offering. At the end of the day this only really matters if you have a very strict match director or if you are competing at nationals where there is a technical inspection. If you make internal modifications that aren't visual then you are probably fine, but a different trigger shoe might raise some flags. What they should do is clarify the rule to include modifications but then stipulate a minimum pull weight like other NRA matches do for specific competitions/classes. For example, in smallbore silhouette hunter class there is a minimum pull weight of 2lbs, but no banning of aftermarket triggers. I think the banning of aftermarket triggers (which only came into effect this year for base class) was a big misstep and a large reason that I am not using my Ruger this year. I will ask for clarification on the rules since I most likely will attend nationals and will want to make sure I'm in compliance. I will make a video about my findings.
