Interesting. I have a 457 American. Where do you go to order kit ? I keep adjusting my trigger down, not where I’d like it. A little apprehensive about going too far. BTW, a mini 7mm wrench is size for the lock nut. What happens if I do go too far ? I’m a rookie at this. Thks.

The factory 457 will not let you go to far because the sear will not engage. You can order the spring kit from yodave just do a Google search

+1 and once you have established where sear will not engage, start coming back up until it will pass a bump test

I don't clip them, I grind them down until they are the length I want. Thousands of rounds later I'm still pleased as punch with them.

But then I don't want a pull-weight below 1 lb, or 12 oz. at the extreme. Below that adds zero to my accuracy and I get too many discharges before I wanted them, which kills you in a match.

Thks guys. I’ll study that drawing. Still a bit confused - is the pre travel adjustment the sea engagement . Hardly any pretravel there. I’ve been turning the middle screw out after loosening the jam nut. Probably one full turn out so far. Definitely lightened pull some but I’d like more. If I keep going will the tiny screw just come out or what ? Just got no clue. Thanks for help and patience with a rookie.

Oh yea - I have put the action screws back exactly where factory set them. Marked with sharp lead pencil.

Ok here's what I do.
1. turn #51 out a least one full turn
2. cock the bolt with drywall anchor or snap cap in place, turn #49 until the striker releases. Then start backing out #49 1/4 turn at a time until a cocked bolt will pass a bump test.
3.lossen nut on #53 cock action again, turn out screw until rifle fires, cocking bolt each time make 1/4 turns in until will pass bump test
4. cock action, turn in #51 until fires. Cock action each time as above, while backing out #51 1/4 turn at a time. Until it will pass a bump test with no creep present.
Hope this helps
LOL may take a bit of tinkering but your not going to hurt anything and all springs are captured by the trigger. So even if a screw comes out during adjustment you are not going to loose the spring

This way of adjusting will work on most all 3 screw triggers, including Remington, Winchester, CZ Ect. Centerfires.

Factory settings on action screws are not always the best. I would suggest getting an inch pound torque driver (the Wheeler Fat Wrench come to Mind) Start with 20 inch pounds on each screw and adjust up from there if needed to find the sweet spot with your particular ammo.

Wow Wyocaddis !! What a GREAT reply and explanation. Thank you very very much my man. I’ll work on that this weekend for sure. Wanta get this rifle set up right. It’s pretty darn good now. I am really enjoying this 457 and it’s certainly more accurate than I am. Been shooting with guys at the local Isaik Walton range. Those guys have got some nicely set up rigs. CZ s and Anschutzs. Anyways, THANKS again Wyocaddis. I’ll post my experience and results when done. Respectively, BirdieBirdie.

One more thing when all done adjusting trigger, make sure you can cock the bolt apply safety. Then release safety without the striker falling. Safety first

Absolutely. And will do Wyocaddis. I definitely owe you lunch ! Tell you something - I immediately wrote the instructions down on legal pad because I am not very proficient at this electronic stuff and didn’t want to loose it ! LOL. Me being an old school dude. I have read and studied over it - broke out owners manual and visualized doing it. - 51 being dead after travel - 49 being trigger set or pre travel - and 53 being pull setting. Itching to get on it but with work and grandkids spring ball starting up, it will be a Sat morning project and afternoon op check on the range. Can hardly wait. Definitely will post results. Owe you one my man. Later.

Every trigger adjustment thread comes with this: Adjust triggers at own risk as one's adjustment may not be the same as others, Adjustment voids CZ warranty It is up to you if you want to proceed

49 is sear, 51 is creep or pretravel. #53 is weight of pull. But adjust them in the order I have given. This will ensure you the best results for your rifle as each spring is a tad different
