CZ550 torque spec?

Is there a torque spec for the stock bolts on a CZ550 Safari Mag? Last forum I was at said "get 'em as tight as ya can". Imagine there should be more to it than that. Also, is there a torque spec for the crossbolts? Mine came with 2. Guess it's something new CZ has added to the Safari.

Thanks!

Dear Sir:
With a well fitting paralell tipped screwdriver that correctly fits the stock screws I'd just tighten them about as tight as is proper- I know that's not a good answer but I feel that they shoiuld be tight enough so that the bbl' and action cannot move.
The figure is floated around of about 60 foot pounds but I think it depends of the stock and bedding method. In some senarios I'm sure 60 fp. would be too much. I tighten my Mauser rifles with the idea that when the screws tighten up and "quit" with a good hold on the screw driver they're OK.
Thast CZ action in a very good one!

P.S. I'd like to have a CZ in 416 Rigby.
 
Thanks, Harry. The more I ask, the more I get that particular answer. The reason I'm so stuck on a spec is 'cause I've heard/read overtightening can be detrimental to accuracy, not to mention the action itself. Certainly don't want to bugger anything up.

I suppose I could either ask CZ-USA, or get a reverse torque tool and see how much it takes to remove them. I've not yet taken possession of the rifle...that'll happen on the 22nd...so the bolts should still be "factory set".

In any event, thanks again for your response.

Dear Sir:
Be careful using thar torque in reverse (most all torque tools read in reverse) because when you screw steel screws together they seem to "grow together" like rifle bbls. when set to the action will be the devils own to break loose sometimes. I don't think a certain torque would be viable due to the many stock configurations and attatching methods. Many degrees of tightness are bandied about but you'll know when "it's OK"
On plastic stocks at 65 foot pounds would collapse!
I DO NOT approve of "pillar-bedding" for a number of reasons!

Wow

Harry I think you may mean 60 inch pounds. I fear 60 ftlbs would break the stock. I know that on Remingtons it is 65 inch pounds. I've not heard a figure for the safari guns, but they use a similar screw and torque figures are for the screw itself. I would say 55-65 inch pounds would be good.

Dear Sir:
Yes, I stand corrected it would be inch pounds. I stand corrected! Thanks. I apologize for guessing. Proves my point - 70 years old - we're still learning!

From the Remington web site:

Synthetic & wood stocks should be hand tight, which is 30 to no more than 35 inch pounds. The Sendero & Police stocks are tightened to 45 inch pounds from the factory.
 
At the LE armorer schools they instruct us 65 inch pounds. First hand I've had better luck with our sniper rifles at 65. They all shoot .5 MOA or better.
 
Tech manual

Here is the page from the tech manual

H-S Precision makes those Remington stocks that have aluminum bedding blocks. The 65 in/lbs only applies to those "Remington" stocks. H-S has always shown 65 in/lbs for the proper torque; have no idea why Remmy says 45 in/lbs.

I've been torquing my VS stock to 65 in/lbs for years now.
 
Here's Remington's reply for the Police and Sendero stocks: (FWIW)

"Thank you for visiting Remington Country. Torque settings for Sendero & Police stocks can withstand up to 45 inch pounds but we do not recommend any more than this."
 
Sorry KDM that your thread got derailed.:o I have two CZ 550 rifles coming. One 458 Lott and a 416 Rigby. I'll look in the manuals and see if there is any info on the torque specs.
 
Thanks, Lazy D...naw, it didn't get derailed. Just a little sidetracked maybe, but not derailed. Besides, it got others talking about their rifles, which is what this forum is all about! Info comes sooner or later.

What I need to do is e-mail CZ for the definitive answer (my manual said squat about torque specs). Still have to do that.
