Torque settings for attaching stock to barrel on Mosin?

Anyone out there have suggested torque setting to use when putting a 91/30 back together? I was just cranking the two screws down as tight as possible, but was told that it should be much lighter than that. Remington site factory specs are only 20 inch-pounds for some of their wooden stock guns.
Any advise would be appreciated.

Thanks,
Dave
 
Looks like some are barely on there - got this off a gunsmithing site.

Torque Settings for Wooden Stocks
Wooden stocks are the most easily damaged. The maximum torque that should be used on wooden stocked Remington 700 rifles is 15-inch per pound. This is more than enough torque to hold securely the action in place but not so much that the wood is cracked or otherwise damaged.

Torque Settings for Synthetic Stocks
Synthetic stocks are well known for their strength and durability. Because the synthetic material is custom fitted to the action and due in part to its high strength, action screws can be torqued much tighter than on a wooden stock. Forty-five inch per pound is recommended by Remington as the maximum torque for action screws on Model 700 rifles with synthetic stocks.

Torque Settings for Composite Stocks
Precision target and bench-rest rifles are generally outfitted with heavy composite stocks. These are some of the strongest stocks found on modern sporting rifles. As such, the actions on Model 700 rifles equipped with a composite stock can be tightly secured with a maximum torque of 65-inch per pound

As an Aircraft mechanic who uses a inch-lbs torque wrench daily, I can tell you 15 inch lbs is finger tight.
 
I wouldn't get too wrapped around the axle about torque values. For close to 40 yrs I've used a Chapman driver with a 3.5 inch shaft and a properly fitting tip to tighten a wide variety of military and civilian guard screws as tight as I can get by hand. They all stay where they should. No one in the military ever used a torque spec to tighten guard screws on these rifles.

Quite right. I was a gun plumber in the Canadian army. There was no such thing as a torque spec for this kind if stuff.

I wonder how many conscripts had to stop in the middle of battle to make sure their Mosins were screwed on just right...

'Not so tight, Ivan! You might damage the wood!'

This. Mosins were made to last in the hands of illiterate peasant conscripts fresh off the collective farm, at the end of a pretty sketchy support train, in Russian conditions. They are somewhat overbuilt.
 
The one history book I have states that each Russian platoon was accompanied by a highly trained armourer-tech, who carried the Tula torque wrench in a special ornate wooden pack frame that looked like a Faberge egg. You'd crack the egg in time of need, and the next nine layers in the storage box were all those little Ukranian "baba"wooden dolls, in progressively smaller sizes. The smallest inner doll held the torgue wrench. A dude who looked like Doctor Shivago, complete with fur hat and silver fox coat, would run across the battlefield, doing shoulder rolls into foxholes, to torque the wooden stocks on the Mosins. Sometimes there would also be bellalakka music playing.

Looks like the consensus here is to crank those two babies down, real good.
 
Tighten the screws with differing levels of intensity depending upon the quantity and quality of vodka consumed... But in reality isn't the pin tool provided with most of these rifles equipt with a small flat screw driver on the tip?

That's what I use to snug mine up with and no issues in almost 4 years of use by me and most likely the 70 years prior to my possession of the rifle. IIRC didn't the Finns have a tool that had a nice arctic birch handle which allowed you to get a better torque on the screw head?
 
The other big issue with guard screws is about selecting the proper screwdriver so that the screw slots don't get buggered as many are. Folks should look for a screwdriver tip with flat sides that fits the slot well. A common tapered side 'driver blade will tend to turn out and bugger the edges of the slot when torque is applied.

There are a number of gunsmith screwdriver sets with interchangeable tips available that do the job. I've used the Chapman set for many yrs and keep one set on the bench and another in my shooting box.
