Action screw tightening ?
Was watching a utube video tonight and the presenter was tightening his action screws while breaking in his rifle (accuracy international).
Anyone here do this on their bolt rifles as part of maintenance?

A torque driver is a very good tool, to have.
So yes, I do torque my action screws, just be advised not all actions and their screws are the same, goggle is your friend.

What he said.
I have found that if a stock is properly pillar bedded torque is static. If thats the case I am pretty consistent with 55 in/lbs.
Other than that, Google is your friend.

Note: on firearms with 3 action screw use caution on the middle screw. Firearms with aluminum trigger gaurds can be broken . They don't need to be torqued to the specs of the front and rear screw. A little locktite on it and " barely snug". ( techno term)

I don’t know why the utube demo would tighten the action screws while shooting a break-in?
I think about 60 inch/pounds is typical for action screws in non compressible stocks (aluminum block or pillar bedded). Some manufacturers have their own torque specs. I would never consider using loctite.

I'm under the impression the Rugers are 60+ on the front with that angled screw? They say tighter the better on that one.
It's sure snug I stopped at 50 maybe 55 I think on Ruger, back one maybe 30.
My Remington's are 40front/30rear. Rimfires are 20-25.

Try 60 in lbs on all 3 screws and let me know how that goes for ya....
Don't do this, you'll likely break the trigger guard.(3 screw set up)
The point is Mr 50bmg gave some absurdly un warrented advice.....

65 inch lbs only applies to the action on a Remington 700.

This is off of Brownell's website.
The main purpose for having a torque specification on an action screw is to offer the end user (who may not have the technical expertise or opportunity to verify that the action is properly seated in its stock) some sort of reference for the sake of expediency. If you consider the myriad of torque specs offered by the major firearms manufacturers this becomes obvious. Presently, Remington’ website is offering a spec of “no more than 45 in/lbs” on the action screws of the 700 VS and 10-15 in/lbs on the standard 700. In the past we have garnered guard screw specs from Weatherby (65 in/lbs), Winchester (25 in/lbs), and HS Precision (45 in/lbs). I expect that all of these specifications are potentially subject to change when production changes are made during any retooling or redesign. It has always been my opinion that having a consistent torque on the action screws is more important than the number of foot lbs.
As you can see, torque specs for different actions is all over the place.

It doesn’t take long to google it and save yourself some money

Beyond securing the action, the purpose of keeping torque within the limits is to avoid compressing a plastic or wood stock. Actions that sit on an aluminum bedding block that bottoms on the trigger plate or on pillars, are not suseptible to compression so can be snuggged tighter. I suspect that most manufacturer recommendations are based on ther production wood/plastic offerings. I generally stick with 40 inch pounds on the compressible stocks and 60 inch pounds if fitted with aluminum bedding block/pillars.

Hope this is t a derail
I just ordered an MDT Ess Chassis during there Black Friday sale. What are the torque specs for this with a Tikka T3?
I am jumping the "gun" a bit on this because I am guessing it hasn't even shipped but I am so excited about the purchase.
Are the torque specs based on the chassis specs or the action specs of the specific gun maker? If so why?

Mark i would email MDT and see what they recommend for torque.
