Torque Values for CZ455

[Snuggie]

Does anyone know these? My barrel was completely floated before my smith did a trigger job. Now I have resistance at the end.

Many thanks Gary!!

Is that the value for the barrel attachment screw (just to be clear)?
I had a friend who did quite a bit of testing on what action screw torque gave the best response to accuracy. It was eye-opening due to the fact it shot best with front and rear screws at different torque settings.

The action screws that attach it to the stock. CZ says 25-30 in lbs. Can you elaborate please.

He wound up with a different torque value for the front versus rear stock screws. Sorry, I don't remember what those wound up being but I saw groups go from 3" to 1 1/2" at 100 yards. His stock was the Manners so may be totally different deal for the wood stocks. I seem to remember he was in the 25-30 or so area but more on one screw than the other.

Thanks man! Appreciate the support info. R&D time!

Not wholly accurate. I know what CZ says, but call them in Kansas City and the gunsmith will tell you never above 24 in/lbs or there will be a big squeeze on the wood, laminate or composite, bedded or not.

You will find your sweet spot after a lot of shots by adjusting the screws up and down the pressure ladder anywhere from 24 down to 16 in/lbs. It is tedious, but the sweet spots will be there.

I totally agree!! I tried going to 24in/lbs and it was still not floated. Now I know as you say, from 24-16 makes perfectly good sense. Many thank you's sir!!

Do these tq values hold true for the Manners Stocked Precision Trainer?

Thanks

IDK. I just know what the manual states and what the gunsmith at CZ says. Give them a call in Kansas City.

BTW- You may have to sand down the barrel channel to get it to float again (OR go back the gunsmith and have him do it on his dime). Either way, make sure there is a thin, but complete coat of water sealant in the newly sanded area of the channel.

How light on the trigger? If a pound or a bit less, you can do it yourself with a YoDave kit for under $40. If you want it at 8-10 oz, an Ace Hardware spring (old stock #144) will get you there for under a buck. Fastenal is another source.
