Torque Settings CZ457 VPT Action Screws

[reichco457]

I would like some recommendations for Torque Settings for the action screws for CZ457 VPT. The stock is a Manners T4 with pillar and bed. CZ uses the same manual for their 457 line up wood or otherwise. Your real test adjustments would be helpful!!
Thanks for the information......

Do you have torque wrench?
If you do, I strongly recommend to try for yourself.
If not, one way is to just keep turning both screws little at a time and then mark the screw head carefully.

There is a rifle and stock specific sweetspot to be found.

I think what Near Miss was getting at is that each rifle will perfom better at different torque values. In my experience with aluminum pillars, I would say to start at 15 inch pounds and work your way to 40. Shoot several groups at each new torque value. I've also found that the first group is usually an anomoly, disregard it good or bad. The action kind of settles in under it's new torque value each time you tighten or lighten it.

Did you put your 457 together yourself? I love my T4 stocked 455 VPT! My 457 VPT has a version of the PRS1 Manners stock. Either way, they are incredible stocks!

Disclaimer: 40 inch pounds is not recommended for the polymer pillars in all other CZ 457 models. I never torque beyond 30 inch pounds with polymer pillars.

with the ever present caveat of your mileage may vary... i shoot my 457 VPT at 35 inch pounds.

Couldn't have said it any better. Mine likes 30, with 20 being almost as good. These rimfires are such fickle creatures.

35-40 is where my CZ's like

Thank you very much for this advice!

These Torque settings are great, good benchmarks to try at different settings. I have a Wheeler Torque wrench now, so hopefully I can dial it in. Thanks All for your feedback!!! Totally helpful.....

The CZ455 I replace the thumbhole with a used Manners stock I purchased off the Hide. It’s my dedicated .17hmr. The new CZ457 VPT came with the Manners Carbon Fiber Epoxy stock. I did replace the bottom metal with Anarchy Trigger Guard. Just wanted to get feedback what Torque range works. Good feedback was provided.

So I plan to use my Wheeler Torque Wrench and try different settings and groups as suggested.

Not a CZ that I own but I just converted my newton meters to in-lbs and it says 35 also.
Before bedding it shot the best set at 10 in-lb.

Really got serious about Action Torque on my 22's after watching some Videos from the LRSU guys shoot their Match 22 rifles at different torque settings and it really opened and closed groups depending on the torque. I was really scared to leave it as low as 5-10in lbs as that just seems so low, like barely over finger tight. My CZ455 in a Boyds Stock I run about 30-35in lbs and that seems to have the tightest groups but it seemed to open and close groups throughout 10in lbs - 40in lbs just like when your doing load development on your large rifles with powder. Im not sure if this is more to do with how tight the action is or if it's messing with the harmonics of the barrel or what but it def is something you can play with to improve your groups...
